Preface
The Germplasm Improvement Subprogram organized a workshop and think-tank on management and use of international trial data for increasing breeding efficiency at Ciudad Obregon, Mexico on January 21-22, 1992. Participants included scientists from INIFAP (Mexican National Institute of Forestry, Agriculture, and Livestock Research), Cornell University, the University of Queensland (Australia), India, ICARDA, and CIMMYT.
The workshop explicitly recognized that data associated with germplasm are valuable resources that enhance the worth of germplasm for both plant scientists and farmers of the developing world. The Wheat Program's planned Data Management System embraces this principle and will organize information around the germplasm to which it refers, rather than by the source of the information (e.g., a specific trial).
Selected papers presented during the workshop and included in this Special Report provide a point of departure or bench mark for our future breeding strategies and planning as we strive to improve both CIMMYT and national wheat breeding programs. Selected discussion notes are included after each paper. Appendices 1-4 provide additional background and details about CIMMYT International Wheat Nurseries and the Data Management System that may not be detailed in the selected papers. Appendices 5 and 6 provide listings of cooperating locations for all nurseries and ISWYN genotypes of which we would appreciate assistance in making corrections.
This Wheat Special Report on the management and use of international trial data emphasizes the importance of shared knowledge. But please keep in mind the information in this report is disseminated with the understanding that it is not published in the sense of a refereed journal.

Initial Discussion
Rajaram: From a breeders' perspective, analysis of yield data is certainly required, but how much is too much? Historically, ingredients of the CIMMYT bread wheat breeding recipe have been:
• Shuttle breeding. • Knowledge of parents, adaptability, disease resistance, quality, etc. • Stability of performance over time and space. • Combining ability. • Average Coefficient of Infection for rust diseases. • Intuition. • Simple experimental designs and quick analyses.
Fischer: What has been the influence of notes coming back from the international� screening nurseries and yield trials on breeding decisions across mega-environments?� Rajaram: The yield nurseries have been the best. The ISWYN, for example, has� educated us on where our lines stand. In recent years the ESWYT has been helpful, but� without the ISWYN, we would have no idea of what breeders would need in Zimbabwe,� for example.�
Fischer: Have the international trials been more or less important over time?� Rajaram: Importance has remained about the same. Information related to yield has� always been very important. The major importance of the screening nurseries has been� the distribution of gennplasm to national programs.�
Abdalla: How do you feel about the mega-environment concept?� Rajaram: It is a natural evolution. That is not to say that gennplasm will not cross ME� boundaries.�

Shaping the Second Revolution--an Historical Perspective on International Trials

Summary
A revolution in wheat breeding occurred with germplasm exchange. The second revolution will exchange information related to germplasm, not only adding value to the germplasm, but also strengthening bonds between institutions and between scientists. We are on threshold of dramatic advances, limited only by our imaginations in using them. Positive dynamic feedback between genetics and environmental information will provide unprecedented insights into crop adaptation.
Introduction
Norman Borlaug spoke of a revolution in wheat breeding brought about by germplasm exchange. I foreshadow a second revolution driven by exchange of information relating to germplasm. The international nursery system will provide the cornerstone of this revolution, which will increase breeding efficiency, with the major beneficiaries being farmers in developing countries. Further expansion of the nursery network is unlikely, but major advances in efficiency must occur.
The international nursery system is user-driven with CIMMYT managing, on behalf of cooperators, the associated data that are freely available and will become increasingly accessible with CD-ROM and other technologies.
Small Leaps Forward
Mechanization, computerization, and robotics Although this workshop focuses on data exploration, it would be unsound to forget the related areas of experimental design and mechanization of nursery preparation, including robotics, in the overall international nursery scenario.
International feedback loop International nursery data provide feedback to CIMMYT breeders. There is an element of recurrent selection in the process of distributing elite germplasm from Mexico and recrossing or discarding this material in subsequent cycles, on the basis of international performance. Anyone who has planned crosses in Obregon will attest to the fact that overall yields in international testing and less formal data, such as notes from outreach staff, are used extensively. One of the challenges before us is to make the feedback loop, to CIMMYT and to others, more efficient. This will occur through:
• Better data exploration. • Quicker turnaround of data. • Better access to raw data, results of analyses and interpretative summaries.
Data exploration and breeding An extensive battery of techniques is available for data exploration and speakers will detail some. Such techniques complement but in no way replace the intimate field experience breeders have for their germplasm. I have a profound respect for breeders' knowledge of their germplasm, including an uncanny ability to identify superior crosses. In tandem to these skills, newer statistical methods are useful in identifying subtle
2�
differences among sister lines and in rapid assessments, from wide testing, of adaptation of new germplasm. Seri 82 appears the most broadly-adapted, high-yielding spring bread wheat and international data exploration forewarns breeders of the Achilles' Heel of such outstanding widely sown germplasm in a way that is impossible with national testing. For example, Seri 82's leaf rust resistance depends on Lr23 and Lr26 and its superiority is tending to decline in locations with heavy infection of BYD, septoria tritici blotch and Helminthosporium species. This warning allows timely initiation of corrective backcrossing and other measures.
Because different major stresses with time may be detected from the results of international nurseries, as a result of many random processes in play, we must be ready to use what surfaces. For example, identification of a cohesive group of locations subject to heat stress in ESWYT-9 allowed inferences about superior germplasm for such conditions, but different stresses emerged in the next year.
Time-lag problem The ESWYT-lO bulletin provides some of the flavors to come in the area of data exploration. These analyses, however, do not attack the time-lag problem, but a joint ITYN-21 and -22 bulletin is planned for this year to bring the dissemination of the second year's analysis forward, while, at the same time, providing a prototype for future desk-top publishing initiatives for international nurseries.
Short-term versus long-term analyses To date, the lead in newer analyses in the ESWYTs has given year-specific results, but moving from short-term considerations to long-term ones is the theme of a major analysis of ISWYN data, to be presented by another speaker. Long-term relationships among locations will be important in refining the definitions of mega-environments.
Analysis or pathological data Multivariate exploration of disease data has been largely ignored and correction of foliar scores for height and maturity to better identify genetic sources of resistance has been infrequent.
Adding value to seed through data Where possible, CIMMYT should distribute existing data with nurseries to aid in the selection efficiency of clients. For example, there is much information on bread making quality generated before germplasm is distributed in an ESWYT.
Impact and singing for our supper CIMMYT will increasingly have to sing for its supper. To this end, the next impact study for germplasm will be facilitated by arranging our proposed databases to store the origins of wheats (especially with respect to CIMMYT's contribution) according to the system used in the recent impact study.
Great Leaps Forward
I have spoken of small improvements of an evolutionary nature in nursery analysis and reporting. However, relational database technology heralds the great leap on which the Wheat Pedigree Management System (WPMS) is based and on which the Data Management System (OMS) will follow. I refer to other speakers and Appendix 1, which outlines OMS and its query structure.
3
Removing barriers to association WPMS overcame barriers to association by uniquely identifying wheat germplasm. The line Siete Cerros was represented no less than 14 different ways in ISWYN bulletins and one had to know a lot about wheat (and a little Spanish) to realize that all the associated data related to the same wheat.
Crossing data frontiers WPMS overcomes such ambiguities and redundancies and lays the foundation for DMS, which will integrate information from different sources around the germplasm to which it pertains. DMS will make possible many powerful associations between genetic information and performance data. This interface was seldom crossed because of problems in association of data from different sources. Detailed genetic information generated in laboratory studies was seldom coupled to field performance data for several reasons. One was a different scale of operations. Thousands of lines might be evaluated in the field with the resultant data eventually finding their way to a dingy end on a series of flat files on magnetic tapes. The results from the more intensive laboratory test on a limited number of genotypes might be committed to paper. Even if the researchers involved in the separate efforts were aware of each other's work, combining the data was never considered because there would have been so many gaps in the intensive laboratory information if combined with the field data in a flat file. Relational databases make cross referencing these types of information feasible and efficient. Today, decisions on which types data should be stored are less critical. As data storage becomes increasingly cheaper relative to data generation, the question becomes: on which characteristics do we require rapid querying?
The scope of DMS will ultimately embrace data from international trials, national trials, the Wheat Germplasm Bank, quality and pathology laboratories, and research in molecular biology, as well as hopefully interfacing to a recent Canadian initiative for a directory of elite germplasm for studies of plant mineral nutrition.

Genes and the environment: dynamic feedback� Here is an example of how data integration might function. If we knew the genetics of� boron tolerance of only one or two entries in our database, but could extract international� performance data on them, implications about the distribution of boron related problems� could be made. Conversely, better knowledge of the environment facilitates typing� germplasm (Figure 1).�
Integration of isolated rust research� Other powerful new associations may be possible by enhanced integration of rust data.� The existing international nursery data system accommodates Modified Cobb Scales and� for this reason has under-utilized a wealth of data generated on seedling reactions, many� of which relate to known races. McIntosh in Australia and Smit and co-workers in South� Africa regularly return such meticulously recorded information and they are generated by� CIMMYT's own pathologists. While imputing rust genes from field scores may be� possible by multivariate analysis of field scores alone, by extrapolation from responses of� known genotypes to responses of uncharacterized germplasm, integrating such trends� with seedling reactions will strengthen the process.�
Discussion Notes�
van Ginkel: Is it possible to identify 10 key locations so that we can get data back� quickly?� Fox: We should not be getting data back from key sites only. We are not bogged down� necessarily on the return of data, but on how CIMMYT processes it.�
Rajaram: We can't blame delays on the cooperators. We take 2 years to process the� data.� Fox: I agree, that's what I'm saying. We are going to desktop publish some key nurseries� as a prototype and thus circumvent the old bulletin generation system.�
van Ginkel: The best cooperators will send the best data early. What do we gain by� waiting?� Fox: The Southern Hemisphere is 11 months behind anyway.�
Abdalla: Bulletins are not the only means of sending information to cooperators. There� are other ways, such as visitations, etc. Maybe we need to consider other means.� Fox: Send information, such as quality data, with the seed.�
Yau: How can we go about getting better disease data? Cooperators use different scales� and even then can one trust the data?� Fox: This is not much of a problem anymore--at least for CIMMYT--since our Outreach� staff has been working hard to gain standardization across national programs.�

Statistical Analysis of International Yield Trial Data in ICARDA's Cereal Program
S.K. Yau� International Center for Agricultural Research�
in the Dry Areas (ICARDA)�
This presentation provides: 1) a brief introduction about ICARDA's international/regional cereal nurseries, especially yield trials, and 2) an explanation of the approach and procedures used by ICARDA to extract information on entry response and adaptability and site similarity.
When ICARDA was established in 1977, an international nursery system based on CIMMYT's experience was already in place. Initially, there were segregating populations, observation nurseries, and yield trials. In 1978, the crossing blocks were added. Recently, trait-specific nurseries and gerrnplasm pools for disease resistance were established. These six types of nurseries cover the requirements of most national programs.
In 1978, there were only three yield trials: 1) barley, 2) bread wheat, and 3) bread and durum wheats for rainfed areas. A yield trial for durum wheat was added in 1979. ICARDA now has a joint mandate with CIMMYT for wheat improvement in West Asia and North Africa (WANA). As experience has accumulated, it became apparent that the WANA is a heterogeneous region. So for the benefits of the national programs, the yield trials were gradually divided and targeted to one of the region's three mega-environments (Le., high altitude, lowland with low rainfall, and lowland with moderate rainfall). In 1991, there were four barley, three durum wheat, and two bread wheat yield trials.
About two-thirds (more for wheat, less for barley) of the yield trials are sent upon request to cooperators in the WANA. Asia and Mediterranean Europe receive some trials, while the rest of the world receives a few. Following the recent agreement between CIMMYT and ICARDA, the joint wheat yield trials will not be sent outside WANA in the coming season. The total number of sets sent to national programs increased from 99 in 1978 to 572 in 1986. Since then the numbers have declined to 443 in 1991 as seed requests are now better scrutinized to ensure that a nursery is appropriate for the area making the request.
All of the yield trials were/are of the same design--lattice (RCB before 1990), three replicates (four before 1988), six rows of 2.5 m spaced 30 em apart, and 24 entries (including a local check, a long-term check, and two or three other checks). Many entries and growing sites are different each year. There is no individual randomization for each site.
Although the international nursery system was established in 1977, it was not until 1984 that a scientist was placed in charge of the operation full-time. The main emphasis of that first scientist was to computerize the annual reporting and the development of computer programs. When I acquired the position in the summer of 1986, I felt that my challenge would be to provide better statistical analysis for each year's nurseries/trials and to conduct in-depth analysis of the vast amount of data collected over the years.
Since 1987, the following analyses have been conducted and reported on in the annual nursery reports: 1) nonparametric adaptability, 2) relative yield, 3) regression, and 4) clustering.
6
.For nonparametric adaptability analysis, we use a visual display consisting of locations (rows) and entries (columns). In 'each row, entries with a rank of five or less for grain yield are highlighted. The total number of times the entry is among the top five yielders is shown at the bottom of the display and provides an indication of the adaptability of the entry. Since the locations are grouped by regions, one can also observe whether an entry has specific adaptation to a particular region or not.
The exercise is repeated to show which entries are significantly higher yielding than the long-term, improved and local checks at each location. The comparison with the local check is of particular importance. It draws attention to those locations where the local check performs very well or very poorly. Investigation of these locations is suggested.
The use of entry mean yield across locations with contrasting yields often gives bias to entries that perform well in high-yielding location. However, using relative yield, i.e., site mean coding by expressing entry yield relative to location mean yield give equal weight to each location and converts the simple variance of entry yield across locations from a biological to an agronomic type of stability measure (Yau 1991). So in the nursery reports, mean relative yields and standard deviations (based on relative yields) of entries are calculated for each region. High relative mean yields and low standard deviations indicate good adaptability.
The use of nonparametric analysis and relative yield is simple and fast for indicating adaptability of the test entries. It would be useful for routine analyses of multienvironment trials conducted by plant breeders.
Although the joint regression analysis is carried out for each trial, the usefulness of the method for highly selected entries is doubtful. Analyses over four seasons of the Regional Bread Wheat Yield Trial on rainfed locations showed that heterogeneity of regression accounted for less than 3% of the interaction variance and was not significant, but deviation from regression was highly significant.
For better understanding of the GxE interaction, a multi-variate technique is needed. After reviewing different multi-variate procedures, I chose cluster analysis. Since 1987, we have clustered trial entries and locations on mean entry yields for each location. Yields are standardized within a location before cluster analysis is done. Centroid linkage was used in the early years, but the group-average linkage is being used at the moment.
Examples of the usefulness of cluster analysis were presented on entry as well as location grouping in Yau et al. (1989, 1991).
The Additive Main-Effect and Multiplicative Interaction (AMMI) model has been suggested to be a powerful tool for analyzing GxE interaction. The postdictive model has been tried on some data sets, but the results were not encouraging. The predictive mode will be tried as soon as we obtain the program.
Besides the routine analyses carried out for each year's yield trials, greater use of the international nurseries as a research tool for more penetrating analyses of GxE interaction is being attempted. The possibilities to work collaboratively with CIMMYT, advanced institutions and scientists working on agro-ecological characterization are being explored.

AMMI Analysis of Yield Trials
Hugh G. Gauch, Jr. Cornell University Ithaca, New York
In order for Additive Main Effects and Multiplicative Interaction (AMMI) to be applicable to a given data set, two structural requirements must be met:
• The data must be organized in a two-way table, with or without replication.
• The data matrix must contain one kind of measurement and units, such as kg/ha.
The usual application in agriculture is a regional yield trial organized as a genotypes by environments table, where the "environments" are actually site-year combinations. Basic AMMI modeling is possible without replication, but rigorous assessments of predictive accuracy (using data splitting and validation) and of postdictive accuracy (using F-tests) require replication. An expectation maximization algorithm, EM-AMMI, can tolerate and impute missing data. Also, the smallest allowable matrix size is 3x3, but genuinely interesting results require a larger size of at least 5x5 or preferably 5xlO. It is not allowed for different matrix rows (or columns) to contain different units, such as soil nutrient concentrations, average monthly temperatures, and average annual rainfall. Also the management must be quantitative, not qualitative (such as the flower colors white, pink, and purple).
In order for AMMI to be truly useful, two additional conditions are required:
• The data structure must conform, to a substantial degree, with the AMMI model. When data exhibit significant main effects and significant interaction effects-which is the most common case encountered in yield trials--then AMMI is usually effective.
• Research purposes must call for parameters, estimates, error reduction, tables, graphs, or insights of the sort provided by AMMI. This condition is almost always met because AMMI serves a remarkably rich variety of purposes.
Violation of one more of the four conditions discussed above means that AMMI is not appropriate and some other statistical model should be used. AMMI is not applicable to data in a one-way factorial, nor in a three-way or higher factorial design. For example, a set of genotypes tested in one site for 1 year constitutes a one-way factorial design. However, if these genotypes have an underlying two-way design arising from, say, a diallel cross, then AMMI is applicable. Likewise, a single trial could have an underlying factorial structure in its environmental component, such as a single genotype tested in a single site and year, but with fertilizers formulated in a two-way factorial design having five levels of nitrogen and five levels of phosphorus. On the other hand, an experiment most naturally regarded as a three-way or higher factorial can often be structured or decomposed into one or more two-way subproblems. The most common instance is an experiment most naturally regarded as a genotypes by sites by years three-way factorial design, structured as a genotypes by environments two-way design, where environments are site and year combinations. Especially when experimental sites change from year to year, this can be a fruitful approach because the original three-way perspective would generate an enormous number of missing cells.
9
For a data matrix with different units in each row (or column), the additive portion of AMMI is meaningless, so other analyses are required. Popular candidates involve first standardizing each matrix row to mean zero and variance one, and then applying Principal Component Analysis (PCA), factor analysis, or some other clustering procedure such as incremental sums of squares. More fundamentally, agricultural experiments often generate data structures other than a single two-way matrix. Sometimes multiple observations are made for each cell of a two-way design, such as a genotypes by environments design with measurements of yield, height, and insect infestation. AMMI can analyze each measurement separately, but exploration of their joint structure requires other methods. Sometimes, agricultural experiments generate two or more two-way matrices, most commonly a genotypes by environments matrix of yields and a factors by environments matrix of environmental factors (such as soil nutrient concentrations, temperatures, and rainfall). The joint structure between the two matrices must be explored by other multivariate methods, such as canonical correlation analysis and redundancy analysis. However, AMMI may be useful to summarize the matrix of environmental data in terms of a few vectors, and likewise standardized PCA may summarize the matrix of environmental data. Then simple methods like multiple regression can explore relationships between these two sets of vectors.
The AMMI literature has emphasized the usefulness of the AMMI biplot for model diagnosis (Bradu and Gabriel 1978; Technometrics 20:47-68). If only the additive effects are significant or sizeable, then the analysis of variance (ANOVA) submodel is diagnosed. Likewise, if only the interaction is significant, then the PCA submodel is diagnosed. If the interaction has some special, simple structure--such as FinlayWilkinson linear regressions, or an even simpler joint regression (concurrence)-inspection of the biplot makes the diagnosis evident. If the main effects or the interaction of both has some cluster structure, this will also be apparent. Hence, even when AMMI is not the most appropriate model, nevertheless an initial AMMI analysis may offer the easiest means for diagnosing the appropriate other model or submodel.
If the best research purpose is to classify the sites (or genotypes) into, say, five groups, then it may be best to use a classification method instead of AMMI. Nevertheless, particularly when the inherent variability of the material is continuous rather than naturally clustered, an informal subdivision of the material based upon an AMMI biplot may work about as well as anything.
Although invented in 1952, the AMMI analysis is relatively new to agriculturists. It will take time to assess its usefulness for various kinds of yield trials and various research purposes, particularly in comparison to other available analyses. Nevertheless, a few comments seem in order.
Yield trials with relatively elite genotypes tested in relatively favorable (highly productive) environments typically have most of the sum of squares in environments, then interaction, and finally genotypes. More diverse material tested in more diverse environments tends to have the interaction predominate. In either situation, both of the main effects and also the interaction are all significant, so AMMI is usually effective.
Interaction and main effects present the breeder with very different problems and decisions. Exactly for this reason, there is an implicit wisdom in the venerable tradition of distinguishing and separating main effects from interaction. Interaction disturbs genotype rankings from environment to environment; main effects do not. Hence, it is helpful to have an AMMI biplot show main effects along one axis, and interactions along another axis, thereby showing whether any two genotypes (or two environments) differ in main effects, interaction effects, both, or neither. In other words, the usual decomposition
10�
of the data into genotypes, environments, and genotype-environment interaction is not only a nice statistical model, but also matches up with distinguishable agricultural problems and opportunities. Of course, a slight modification of many other statistical analyses could allow them to make this same distinction. For example, besides applying a clustering alogrithm to the original yield data, one might also analyze the interactions.
Increasing selection gains and containing research costs both demand experimental efficiency. AMMI often gives free extra replications of 1 to 3 times the actual physical replications, whereas blocking typically gives 0.2 to 0.4, so this neglected opportunity to partition the treatment design into a model and residual is often more effective than is the usual analysis of the experimental design. However, since the treatment and experimental designs are orthogonal, both strategies can be employed. These offer remarkably costeffective means for gaining accuracy, which in turn improves selection gain.
A deeper understanding of interactions can clarify the target mega-environments, reveal the implications of interaction for breeding gains, and show the consequences (intended or not) of past breeding policies for the present populations.
The entire subject of heritability, from definitions to analyses, is based upon simplistic additive or linear models. Something new might emerge from revisiting this subject with thinking that better handles interaction.
Without interaction, a single wheat or maize variety would flourish planet-wide. In many ways, interaction is the problem that breeders face. In retrospect, it may seem that breeders' greatest successes (apart from disease resistances) largely concern favorable situations (mega-environment one) in which interaction is mostly sidestepped. But further progress may have more to do with handling interaction head-on.
Summary
Agronomists and breeders frequently collect yield data for a number of genotypes in a number of environments (site-years), resulting in a two-way data table--usually replicated, but sometimes not. The AMMI model combines regular ANOVA for additive main effects with peA for multiplicative structure within the interaction (i.e., within the residual from ANOVA).
AMMI is effective for:
• Understanding genotype x environment (GxE) interaction, particularly with a biplot graph showing both main effects and interaction effects for both genotypes and environments.
• Improving the accuracy of yield estimates, offering an orthogonal and additional error-control strategy to the usual strategy of replicating and blocking.
• Increasing the probability of successfully selecting genotypes with the highest yields, as quantified through order statistics calculations.
• Imputing missing data with the expectation maximization algorithm, EMAMMI.
• Increasing the flexibility and efficiency of experimental designs.
11
Ultimately, these advantages imply larger selection gains in breeding research and more reliable recommendations in agronomic research. AMMI is ordinarily the statistical method of choice when main effects and interaction are both important, which is the most common case encountered in yield trial research.
The calculation for AMMI can be done conveniently by the MATMODEL program (which resides in the CIMMYT VAX computer; see Dr. Jose Crossa for details). For information on this program as well as citations of recent literature, see Gauch and Furnas (1991, Agronomy Journal 83:916-920).
Discussion Notes
Fox: How do we divide resources between better design and better analysis?� Gauch: Generally, one should have fewer reps and more treatments. In an extreme� example, with CIMMYr's connections to a few large centers and many smaller sites, 5�10% of the trial could get you 80-90% of the information.�
Pfeiffer: We gain more if we consider the environment and have the appropriate number� of reps accordingly...also change the size of the plot.� Gauch: It is true that we gain accuracy by enlarging plot size or increasing reps, however� AMMI is an extraordinarily cost-effective way to gain accuracy with fewer reps and� smaller plot sizes.�
Fischer: A lot of our yield performance is based on information from one site in 1 year.� We are confident that performance at CIANO is representative, but do we know that it is� the best predictor of the overall ISWYN mean? In other words, is it the best site?� Gauch: You should be able to use AMMI to find out.
Fischer: Perhaps we should do yield tests at other sites as advanced yield trials, for example, two reps at CIANO and two reps somewhere else in Mexico--would this mean anything to the rest of the world? Gauch: The key word is perhaps.
Fischer: Noise is more than error, in fact it can be biologically useful. For example, say we have 60 sites, but one site has a unique boron problem--this would re-rank the genotypes and AMMI would drop the atypical site out.

Long-Term Similarity of Environments in the ISWYN
Ian DeLacy� University of Queensland�
Australia�
Table 1 presents preliminary results of a manuscript in preparation for Euphytica. Here the locations are divided into 15 relatively homogeneous groups, based on their longtenn genotypic performance. The final study will be conducted on standardized deviations from location mean yield, such that each location-year combination has a mean of zero and phenotypic standard deviation of one. Such a data manipulation ensures that clustering depends largely on genotypic rank changes among environments.
Within each of the 15 groups, locations have been re-ordered in numerical order with respect to their new proposed identifiers. The alternative would have been to leave all location identifiers in their order from the complete dendrogram, i.e., the untruncated dendrogram extended to the level at which each of the locations was a single member group. Either way, advantages of the new location numbering system become apparent. For example, the 23 locations in group 265 are all from Africa, as shown by the fact that their identifiers commence with the digit one. Similarly, the six members of group 313 are from Europe (including the former USSR), indicated by the first digit being a three. Group 339, however, comprises members from Africa, Asia (start with 2), Europe, the North American Continent (4), Oceania (5) and South America (6).

Discussion Notes
DeLacy: The correlation between the yield of a set of adapted lines in a single yield trial and the long-term performance in the farmer's field is essentially "zero"--no matter what you do.
Singh: Should we do analysis on a regular basis or just every 10 years or so? DeLacy: Add new data as they come in to the historical set and see where they fit.
Fischer: There is something about the optimum environment that gives good predictability (Obregon, Giza, Israel, etc.). We were really lucky that we were making all of our selections in Obregon.

Using the Shifted Multiplicative Model (SHMM) to Identify Subsets of� Environments without Genotypic Rank Change:�
II. Clustering Method�

Introduction
In plant breeding, genotype x environment interaction is critical only if it involves significant crossover interaction (COl) (Baker 1990), i.e., significant reversal in genotypic rank across environments. Gregorius and Namkoong (1986) defined "separability of genotypic effects from environmental effects". Such separability implies absence of significant genotypic rank-change. The shifted multiplicative model (SHMM), developed by Seyedsadr and Cornelius (1991b) provides a powerful analytical tool for studying COL The general relationships between the multiplicative terms of the SHMM model and Gregorius and Namkoong's definition of separability are described by Cornelius and Seyedsadr (1991). Conditions considered sufficient for the absence of statistically significant COl were:
• SHMM1 is an adequate model for fitting the data.
• "Primary effects" of environments have the same sign.
Cornelius and Seyedsadr (1991) used an exploratory method for identifying subsets of environments that possess separability of genotypic effects.
In most crop breeding trials, genotype x environment interaction is complex and separability of genotypic effects may not occur. In this situation, it would be useful to have a methodology for finding subsets of environments in which separability of genotypic effects holds. The objectives of this study were to present a cluster methodology for finding subsets of environments with separability of genotypic effects, and to examine the success of the cluster method in reducing the number of significant COl within each final group of environments.
Materials and Methods
Yield data (kglha) from an international maize variety trial conducted in 1987 were analyzed. The trial had eight genotypes grown in 59 locations.
SHMM statistical analysis The SHMM model with t multiplicative terms (SHMMt) is:
Yij = S + ~tk=l "'kaikYjk + eij (Seyedsadr and Cornelius 1991b)
where Yij is the yield of the ith genotype in the jth environment,
S is the shift parameter,
Ak is the singular value for the axis k,
15
ai1 and Yj 1 are the "primary effects" of the ith genotype and the jth environment,
ai2 and Yj2 are their "secondary effects", and eij is a random error.
When the SHMM1 values are plotted against primary effects of environments or genotypes, the diagram shows a set of concurrent regression lines which intersect at yield level y = 13. If SHMM1 is an adequate model and the phenotypic values are located either all to the left or all to the right of the point of concurrence, then genotypic effects are "separable" from environmental effects. Otherwise, there is rank-change on opposite sides of the concurrence point and effects are "nonseparable". If SHMM1 is inadequate, statistically significant secondary effects are an almost sure indicator of nonseparability even if primary effects have the desired pattern.
Finding subsets of sites for which SHMMt fits adequately:� clustering method, distance measures, and dichotomous split procedure� Distance measure (d) between two sites is defined as:�
d = residual sum of squares, RSS(SHMM 1) if the fitted� SHMM1 does not show genotypic crossover and otherwise�
d= min[~gi=1(Yi1-Y.1)2, ~gi=1(Yi2 - Y.2)2].
The latter chooses the RSS of the better of the two possible SHMM1 solutions constrained to not show rank-change, namely, either 13 = Y.1 or 13 = Y.2.
Once d is obtained, clustering is done by the complete linkage method. SHMM analyses are then done on the last two cluster groups (end of the dendrogram) to determine if SHMM1 without genotypic crossover is an adequate model. If this fails for either cluster, this cluster is dichotomously split into two smaller clusters suggested by the next lower branch of the tree in its portion of the dendrogram. This process continues until satisfactory clusters are identified.
Assessing the adequacy of SHMMt Adequacy of SHMM1 for modelling a subset of data was assessed using the following tests:
• Approximate tests, F1 and FGHl, against a pooled error (Cornelius et al. 1992).
• The Seyedsadr and Cornelius (1991a) (SC) test.
• The Seyedsadr and Cornelius/Schott-Marasinghe (SCISM) test (Cornelius et al. 1992).
• A test constructed by analogy to the test of Yochmowitz and Cornell (1978) (YC) for Additive Main effects and Multiplicative Interaction (AMMI) models.
Statistical tests for assessing significance of COl The following tests (Cornelius et al. 1992, Crossa et al. 1992) were used to assess COl among and within subsets:
• Test 1, which requires calulating differences between all possible pairs of genotypes in all possible pairs of environments.
• Test 2, which uses a t-test with a comparison-wise error rate (a) of 0.05.
16
• Test 3, which is a t-test with a defined interaction-wise Type I error rate, i.e., error rate per 2 x 2 subtable tested for COls.
Results and Discussion
Grouping sites with separable genotypic effects SHMMI is not an adequate model for the entire data set because secondary and tertiary effects were significant (Table 1), so we proceed to look for satisfactory subsets of sites. SHMM1 is also an inadequate model in both of the two major groups of sites (A and B) identified in the dendrogram (Figure 1), since secondary and tertiary effects are large and significant in both of these groups (Table 2). The next split fonns groups A1, A2, B1, and B2. SHHM1 is adequate for Al (nonsignificant secondary effect) but not for A2, which is then subdivided into A3 and A4 (Figure 1). SHMM1 is adequate for group A3, but not for group A4 where mean squares owing to secondary and tertiary effects (172 and 141, respectively) are significant by the F1 test. Because site 33 joins the rest of the sites late in the dendrogram, its exclusion from A4 to form group AS improves the fit of SHMM1 (mean square of secondary effects is 111 and not significant). Site 33 is left as an ungrouped site. SHMM1 is satisfactory for fitting group B1 due to the large value of the pooled error variance (301; mean square error of sites 6 and 17 were 263 and 339, respectively). SHMM1 is satisfactory for group B2 (only primary effects are significant).
The cluster analysis has identified five final groups of sites (A1, A3, AS, Bl, and B2) for which a SHMMI that does not display genotypic crossover (Figure 2) is an adequate model.
Significant COl among and within groups Table 3 gives all possible 2 x 2 interactions (I), crossover interactions (COl), and significant COls obtained by Test 1, Test 2, and Test 3 for sites in different groups and for sites in the same final group. The number of all possible interactions between any two genotypes with any two environments is 47,908; 41% of them (19,713) had a COl pattern, Le., with genotypic rank change (Table 3). Of the possible within-group interactions, 34% (4,339) had a COl pattern, while 44% (15,374) of the possible amonggroup interactions had a COl pattern (Table 3).
The percentage of COl that was significant by Test 3 (the most liberal one) was 8% (352) within groups and 16% (2,482) among groups. As percentages of all possible interactions, these are 2.8% and 7.1 %, respectively. These results indicate the effectiveness of the distance measure used in the cluster analysis in reducing the number of significant COls\ with genotypic rank changes within the final groups of sites.
Conclusions
The cluster analysis based on the proposed distance measure appears to do an excellent job of allowing the user to identify groups of environments in which genotypic rankchange interactions are negligible relative to those between groups. This procedure can be effectively used for grouping environments with genotypic separability.

Analysis of International Nursery Data--�Results and Implications for International Nursery Design�
Wolfgang H. Pfeiffer� CIMMYT Wheat Program�
Introduction
"... virtually all phenotypic effects are not related to the gene in any simple way. Rather they result from a chain of physico-chemical reactions and interactions initiated by genes but leading through complex chains of events, controlled or modified by other genes and the external environment, to the final phenotype" (Allard 1960).
The nearly infinite number of these genotype x environment (GE) interactions constitutes a major challenge for plant breeders; selection of high yielding germplasm with consistent performance is based largely on phenotypic traits, without knowledge of the causal biochemical, physiological and morphological relationships. Identification of elite gerrnplasm is further complicated by the dependency of genotypic and environmental effects, and scientist are "... plagued ... by the disturbing feeling that each genotype may have its own characteristic response" (Sprague 1955).
Although fluctuations in performance caused by GE are "masking" genetic breeding values and force breeders to evaluate germplasm over a range environments, the capitalization on specific GE interactions and resulting response pattern in crop improvement is a major source of genetic progress, particularly if the underlying biological factors of GE can be identified. Consequently, the critical importance of GE in crop enhancement has been emphasized. However, opinions have widely differed regarding the methods to evaluate GE, the level of knowledge on biochemical and physiological "pathways" and associated traits required to make "real" progress, and the application of trait/marker oriented versus empirical approaches in breeding programs. A wider acceptance of integrated crop improvement strategies that consider biological and practical, empirical approaches as complementary, rather than alternative, reflects a new trend in breeding and increased knowledge and availability of tools for both approaches.
Since CIMMYT's cereal breeding programs have gradually shifted towards integrated approaches, the role of CIMMYT's International Nurseries in this altered scenario needs to be revised.
Objectives
This paper discusses different types of international yield nursery analysis in the context of applied breeding and the integration of different types of analysis in CIMMYT's breeding concept and strategy.
GE-Interaction Concepts and Approaches
CIMMYT's breeding operations focus on the development of high-yielding, widelyadapted gerrnplasm with built-in spatial, temporal, and system-independent yield stability. Wide adaptation is a key issue in breeding efforts, since this prerequisite facilitates the access and transfer of genetic systems to local germplasm or a direct release. In this context, adaptation can be defined as the ability of a variety to produce consistent high yields over a range of environments (wide adaptation), or over a specific, narrowly defined environment (specific adaptation). In CIMMYT's breeding hypothesis, adaptation is considered as a quantitative character related with yield per se; yield
23�
stability can be defined for spatial, temporal, and system dependent yield fluctuations of adapted genotypes.
The most important prerequisite of adaptation on the genotype level is yield per se and its components. Change in components related with yield per se will, in general, not alter adaptation. Other components of adaptation such as tolerance or resistance to biotic (e.g., resistance to single/multiple pathogens and races of a pathogen) and abiotic stresses (e.g., tolerance to drought and thermal stress) affect environmental yield potential, but also adaptation and yield stability. Incorporation or modification of such a buffering mechanism can increase the realized environmental yield potential as well as yield stability and the range of adaptation. Hence, increasing specific adaptation can increase wide adaptation and vice versa. In contrast to photoperiod insensitivity, which contributes to wide adaptation, photoperiod sensitivity contributes to both yield potential and specific adaptation, but decreases the range of adaptation.
Hence, the information required by breeders involves both genotypes and environments: the evaluation and quantification of genetic yield potential, adaptation, and yield stability of genotypes, as well a characterization of similarities among test sites as defined megaenvironments. Once such mega-environments are defined in terms of GE, the underlying biotic and abiotic determinants should be identified. With stresses recognized, traitoriented selection could reinforce breeding for both broad and specific adaptation.
Based on this concept, data from multilocational international yield nurseries have been analyzed in the past to generate information for the various themes. However, the nurseries were not specifically designed for research purposes and served as germplasm distribution tools.
ISWYN Analysis--Results and Implications
Genotypes The early, more common statistical approach entailed an evaluation of the "total" environment, by analysis of variance of yield data, without identifying the specific environmental factors which determine GE. This approach provided relevant results on adaptive pattern, spatial, and temporal yield stability, genotypic response to increasing levels of productivity, similarities among genotypes and was used to compare locally developed and so-called high yielding germplasm (Pfeiffer 1984, Pfeiffer and Braun 1989). Further, the results permitted conclusions on underlying biological factors of germplasm performance particularly if biotic stresses were involved. The conditionality of the results, Le., their association with the particular set of genotypes and test sites included in the nursery, caused a certain bias and difficulties in their interpretation. Estimates for regression response, stability, repeatability of stability parameters, heritability estimates, and components of variance in the stability analysis are likely to be overestimated due to the extreme diversity of the genotypes and test sites included in the ISWYN. The linear approach largely failed to differentiate among genetically closely related germplasm, e.g., sister lines from the same cross. Problems of a more statistical nature, such as very low portions of "explainable" GE, overestimation of deviations from the regression due to similar or identical site means, etc. are discussed in detail by Freeman (1973) and Pfeiffer (1984).
Test sites Other objectives of the ISWYN analysis were:
• The description and quantification of the selection ability (SA) of test sites--test sites with high SA allow discrimination among genotypes are representative for a
24�
given target area, and repeatable in different growing cycles in terms of their environmental conditions.
• The grouping of the test sites into agroecological zones.
• The identification of key sites with high SA on a global level and within agroecological zones--based on the assumption that selection at those locations should maximize genetic gains.
• Identification of the underlying biological factors of SA and agroecological groupings.
The results and methods of this study have been published by Braun (1983) and Braun et a1. (1992). The regression technique used to estimate genotypic response was used in a reverse manner: the regression of the entry grain yields at a test site on the entry means across test sites can be used to describe the discrimination among entry mean yields--the higher the regression coefficient, the better the discrimination. The deviations from this regression can be used to describe the accuracy and should be small. Other parameters used to describe SA are the heritability of a test site, and the correlation between the entry grain yields at a test site and the entry mean yields across test sites for all test sites included or subgroups of test sites. All these parameters can be combined in one measure (Vtz 1972, Wricke 1971). Since this analysis was based on the same linear model and data as the analysis to estimate parameters for genotypes, the restrictions, problems, and limitations remained the same. The estimates provided a fairly rough picture of SA, clusters of test sites, and underlying biological factors, however, lack of orthogonality and the small number of test sites within the different clusters allowed detailed analysis only for a limited number of major groupings. In general, it was not possible to obtain applicable results for groups of marginal abiotic stress environments with low grain yields in absolute terms, low variability among entry grain yields, low heritabilities, and high error variances. The generation of data with a certain accuracy at such environments may have required a different experimental design and larger plot size; however, the problem of similar site means would have remained. Another major problem encountered was the grouping of locations itself. By using several parameters--correlations among test sites, site mean yields, regression slopes of test sites, disease scores, and heritability, variance and error estimates--a meaningful grouping of the test sites was possible. The procedure and the interpretation of the results are too time consuming for general application--e.g., correlation matrices for a single year can reach dimensions of 80 x 80, with 3160 correlation coefficients to be grouped in an unknown number of clusters or predefined number of clusters.
IWWPN Analysis--Results and implications
Based on the experience with the ISWYN data, multivariate analysis appeared to be the more appropriate technique to analyze 17 years of IWWPN (International Winter Wheat Performance Nursery) data (Peterson and Pfeiffer 1989). Multivariate analysis, such as cluster and factor analysis, consider genotypic response as multidimensional, with each dimension representing a test environment. Conversely, they can characterize similarities among environments in terms of performance of genotypes grown. Thus, both genotypes and environments can be described in terms of GE (Peterson and Pfeiffer 1989, Pfeiffer and Fox 1991).
A parallel study using cluster analysis resulted in very similar groupings. Further, the� grouping of test sites into regional and subregional divisions was facilitated by the� relatively high orthogonality of test sites over years.�

Discussion
CIMMYT's Wheat Program distributes different types of nurseries with different objectives:
• Germplasm distribution nurseries for early segregating (F2) and intermediate products (F3, F4) without request to return data.
• Unreplicated screening nurseries primarily for germplasm dissemination with a secondary function as germplasm screening mechanism (e.g., IBWSN, IDSN, ITSN).
• Replicated yield nurseries primarily to quantify adaptive pattern of genotypes with a secondary germplasm dissemination function (e.g., ISWYN, ESWYT, IDYN,ITYN).
• Specially designed, replicated investigative yield nurseries, such as the International Drought Trial have been distributed occasionally on a irregular base.
Some of the suggestions that resulted from the ISWYN analysis have been implemented: 1) the shift from RCB to lattice design for international yield trials; 2) the use of improved, new methods for analysis such as AMMI, cluster, and factor analysis, which are easily interpretable by breeders and provide additional information on environmental similarities and adaptive pattern of the genotypes; and 3) focus on mega-environments by separate screening and yield nurseries for different agroecological zones with a set of genotypes adapted to the environmental conditions of the mega-environment and standards common to different nurseries.
However, the information potential of international nurseries has not been exploited. The inclusion of differentials for particular abiotic (e.g., trace element deficiency or toxicity) or biotic stress (e.g., nematodes) in screening nurseries with specific instructions for note taking could be used to detect actual or potential production constraints. Once such environmental constraints have been identified, they can be quantified in specifically designed investigative nurseries with plot size, for example, adjusted to environmental variability. The International Drought Trial may have yielded more information for moisture stress situations than several years of ISWYN data: it was distributed to relatively few selected cooperators who recorded additional information on genotypes and environmental parameters; additional information was generated in line source testing and breeders trials. Hence, this allows scientists at CIMMYT base to evaluate the representativity of their selection and testing environments, modify testing environments and methodologies accordingly, and target basic research. Further, expanded multilocational yield testing during intermediate and/or final stages of germplasm development in Mexico maYI result in higher selection gains and substitute for part of the international yield testing with higher overall resource efficiency. Past experience has shown that international cooperators adopt CIMMYT's methodologies and procedures, e.g., new experimental designs. Hence, investigative nurseries can play an important role in human resource development in developing countries. Further, efforts from CIMMYT to distribute germplasm together with data and information, e.g., on milling and baking quality or leaf rust genes, will facilitate selection and increase efficiency in NARCs.

Discussion Notes
Rajaram: In the screening nurseries, maybe we should reduce the load on cooperators by asking them to provide information only on lines that are useful to them. Pfeiffer: Cooperators should take notes for all entries. They should report what lines they selected as soon as possible...Perhaps we should supply data with seed. Singh: Ifwe follow through on Rajaram's suggestion, we would not know why a particular line was not selected--it would be interesting to know if a disease was involved.

Update on The Data Management System (DMS) for the Wheat Program
Henrik Schou and Hector Sanchez� Systems and Computing Services�
Note: For additional background on the Wheat Program's Data Management System, See Appendices 1 and 2.
This paper reports on the findings of a DMS survey conducted by SCS concerning problems and deficiencies involving the management of evaluation data in the Wheat Program. The aim of this study was to identify:
• Current user procedures. • Deficiencies to overcome. • Goals of the new system. • Scope of the DMS project. • Acceptable scenarios for completing the project. • Suggestions for a possible project plan.
Current User Procedures
In this section, we list current user procedures, i.e., the daily operations performed by Wheat Program staff. The aim of analyzing these procedures is not to get a complete picture of the Wheat Program's way of working, but to get a feel for the work flow so that appropriate decisions can be made relative to setting up a functional and userfriendly data management system.
Below is a list of the day-to-day operations done in various sections of the Wheat Program. The codes mean the use of the following:
• S = Special package. • WPFBS = The field book system. • M =No system. • WINS = The WINS system. • WGB = The wheat germplasm bank system. • WSGSS/WSGYS = WSGSS and WSGYS. • FIBOS =The FIBOS system. • EXTRACT =The extract program.� • * = Operations to be considered by the DMS project.�

Data Management System
In this section current deficiencies and new system goals for operations 3, 4, 5, 13, 14, 15, 16, 17, and 18 above are discussed.
Current deficiencies to overcome Deficiencies of the current system expressed by members of the user community in the survey are listed below:.
1) Evaluation data are not always stored.
2) It is not possible to retrieve information.
3) In order to facilitate research on wheat data, a lot of "donkey work" to organize the data must be done.
4) New traits can not be analyzed.
5) It is tedious to make a LOTUS or MSTAT report because the data needed are only available on tape.
New system goals Operations 3, 4, 5, 13, 14, 15, 16, 17, and 18 are supposed to be affected by DMS and the new system goals include the following:
1) All the wheat data should be accessible.
2) Evaluation data must be stored in a format that facilitates researching.
3) It should be possible to add traits to evaluation data.
Acceptable scenarios A brief description is presented here of two possible systems that satisfy the new goals-VAX-PC integration and a VAX-PC network. It is important to realize that goal #1 implies a connection of the three Vax databases--the Pedigree Management System (PMS), Wheat Germplasm Bank (WGB), and the Wheat Program Field Book System (WPFBS)--and the evaluation database that has to be constructed as part of goal #2.
The VAX-PC integrated solution. The three systems--PMS, WGB, and WFPBS--that reside on the VAX and would be interconnected. The Evaluation database would also be VAX-based and connected to the others. Facilities to export data to the PCS for use in MSTAT, Lotus, or other packages would be available. Data would be entered on the VAX or on a PC and would reside in the common data repository on the VAX. Filtering would take place on the VAX.
The VAX-PC network solution. The three systems residing on the VAX would be interconnected, but the evaluation database would be PC-based and not physically connected to the VAX databases. The link to the VAX-based systems would maintained through cross and selection history.
Development, operational, and maintenance costs For either scenario, it is estimated that the whole project will take 4 programmer/analyst years. The Wheat Program will need to allocate resources for the acceptance test,
31�
acceptance test generation, and conversion of evaluation data. For the network solution, an additional network database package would have to be licensed and installed.
Operational costs are estimated to be less than those currently, but will include entry of evaluation data from about 1500 books per year, hardware maintenance, and costs of using standard software packages.
The network solution would have additional costs of keeping two separate databases consistent and of operating a network database.
Maintenance costs will involve fine tuning the system, including correction of minor errors.
Suggested Development Plan
SCS suggests that the project be broken down into units with each unit consisting of analysis, design, and implementation. Each product has to be accepted by the Wheat Program and upon delivery be able to generate acceptance tests and execute acceptance test cases.
Conclusion
The scope of the DMS project is limited to evaluation data from field books and international nurseries. A large part of the project will be the interconnection of PMS, WPFBS, and WGB. The other part concerns the design of a new database containing the evaluation data.
We suggest that a steering committee consisting of wheat scientists and SCS analyst/programmers agree on the steps of the development plan. Ideally, the project should be broken down into smaller units and as each unit is delivered, it should be approved and accepted by the Wheat Program.
Discussion Notes
Sanchez: The PMS conversion is the bottleneck--the Bank system cannot be linked to PMS until the PMS conversion is completed.
Fox: Certain tapes in SCS should not be put on the system--either too old or too expensive to convert.
Fischer: There is not much need to convert historical data. Conversion of new data will be an accomplishment.
DeLacy: Data for potential inclusion in the system should be treated on a case-by-case basis.
van Ginkel: Is it possible to include data from previous years in the fieldbooks? Schou: As long as the data are there, yes.
Fischer: Even if you have all the data at your fingertips, is it humanly possible to use it? It boggles the mind!

Use of Relational Databases in Wheat Breeding
John D. Corbett� CIMMYT Geographer�
"Data is a resource in much the same way that employees, products, natural resources, finances, and other materials are resources" (Relational Databases: Concepts, Design, and Administration, 1991, McGraw Hill)
Wheat breeders generate volumes of data for which the major limitation to use is access. Information access and information exchange offer mechanisms to enhance the efficiency of breeding efforts, if only through the better management of the data a breeder generates. There are two parts to this paper: First, some general characteristics of relational databases (RDB) and how such data management systems might directly affect CIMMYT. Second, I will present a practical or prototype example of how a relational database works (the interface) using data from the International Spring Wheat Yield Nursery (ISWYN). This example will be summarized through a simple listing of the example queries.
Introduction
For breeders, better efficiency can be found in expediting the access to annual trials and in access to historical data as well as germplasm data from other sources (namely PMS and the germplasm bank). One way in which CIMMYT contributes to its cooperators is in the form of seed (nurseries). We need these data. We also need to make the feedback to cooperators faster, more thorough, and more convenient and, thus, these data should be managed in a relational database environment. One possible effect of more timely feedback is the improvement of trial data returned from cooperators.
An untapped source of information is the academic community worldwide. If supplied with our data, the contributions from these off-CIMMYT sources may prove valuable.
A relational database means access to your data and ease of query of these same data.
Goals of the Relational Data Base:
• Access to "all" data--international trials, the germplasm bank, Pedigree Management System, genetic information, environmental data (climate, soils, meteorology), output from crop models, etc. Because there is no positional dependency between the relations, requests do not have to reflect any preferred structure and therefore can be nonprocedural.
• Simplicity: The end user is presented with a simple data model. Requests are formulated in terms of the information content and do not reflect any complexities caused by system-oriented aspects. A relational data model is what the users see, but it is not necessarily what will be implemented physically.
• Application program independence. Data which are accessed by a relational database can be extracted so that it is in a form suitable for many applications (e.g., SAS and other statistical package input files, ASCII text, etc.).
33
• Consistency through use of same data by all researchers.
• Reduction in application development, storage, and processing costs.
CIMMYT can be thought of as an information-driven enterprise. Access to and use of our data is paramount to the success of our enterprise.
Potential users must know what data exists! Thus CIMMYT is actively seeking ways to publish our data in such ways as to maximize utility. CD-ROMs (Read Only Access) offer great potential.
Part 1: The Relational Database
RDBs link "entities": An entity is a uniquely identifiable thing such as a person, place, genotype, or concept about which we desire to record information.
An entity is a logical object, whereas a table is a relational object that can be mapped by a database into physical datasets stored on disk.
An entity can be thought of as a ROWand each entity has some unique identifier (primary key) and attributes (columns, also called fields) and through the keys, some relation with other data.
The attributes of the logical entities will be implemented in relational tables as COLUMNS. Each column must be identified. One or more columns in each table will consist of the unique identifier, or primary key. Relationships and the corresponding foreign keys will also be implemented as columns in tables. Primary and foreign keys should be the only columns that appear in more than one table because they represent the only attributes that appear with more than one entity.
An attribute (also called a field and which appear as columns) is a data element.
A relation is a group of attributes.
Attributes are related through a key and describe some entity of interest.
The RDB begins with the translation of each entity into a relational table.
The RDB can be defined as a collection of interrelated data items that can be processed by one or more application systems. The RDB permits common data to be integrated and shared between corporate functional units and provides flexibility of data organization. It facilitates the addition of data to an existing ROB without modification of existing application programs. This data independence is achieved by removing the direct association between the application program and physical storage of data.
Final comments Our data become an asset that we can make available to NARSs and universities.
CIMMYT will have a distributed database system. Each group has direct control over its data (more efficient data processing =increased data integrity). A network allows for the sharing of such data and the relational database management system (DBMS) allows access to the data.
34
Note that for calculated fields, an ROB will not store the calculated field (Lotus and other spreadsheets do) as the numeric fields that created it are sufficient and are created at retrieval time. Scripts can be created which store the algorithm and these are easily accessed.
The data dictionary (DO) is the second most important tool in the ROB environment (after the DBMS itself). The DD is used to record facts about objects or events in the database environment in order to facilitate communication and provide a permanent record. The DO is based on giving information about the database itself, its contents, and its structure. The DO focuses on data related components: data elements or attributes; data groups, rows, tables; data structure; databases. CIMMYT will need to put resources into the development and design of the data dictionary.
In an ROB environment, the DO is a very important tool for systems design, documentation, data management, and data security. It can be used as a repository to collect the user requirements which are used as the primary input to the logical design phase of database development.
A note on data entry. The relational database and the DBMS use forms to assist with the entry of data. In this way, each bit of information entered into the database is checked for a range of possible values. Thus, yields would be flagged if entered as 10000 kg/ha.
Part 2: An example of possible queries: ISWYN
1) Select all data (germplasm type, rep, yield, disease scores) for all trials in which rainfall was less than 200 mm and yields were greater than 5000 kg/ha.
2) Select all data for cases where disease scores on stripe rust and head rust are high.
3) Select for all cases where Nand P fertilizer were used and yields were less than 3000 kg/ha.
4) Use the cross number for Bluebird (II23584) and find all occurrences of this cross and when grown in an ISWYN nursery.
5) Calculate the average yield of the repetitions for a given site in each ISWYN where it occurs.
6) Count the number of times a select germplasm is used.
7) Select stations used more than eight times and which occur in South America. Provide the latitude, longitude, and elevation of these stations.
Conclusion
The development of a relational database system at CIMMYT will require effort to clean historical data and to change the way in which we view the data we generate. In Appendices 5 and 6, we ask for your input to this process. Appendix 5 lists cooperating stations. Please update any errors you can identify. Appendix 6 provides the common name, a unique identifier, the cross and selection 10 (when known) for all germplasm that has been grown in the ISWYN trials. Please send any corrections to the first named editor. Provide a complete copy of the data in error along with a complete note on your corrections.

Discussion Notes
Corbett: Access to our own data should not be an issue...The Paradox package is very� user-friendly. We will be able to come up with a computer screen that looks like the� cooperators' forms. This will speed-up data input by secretaries and enable them to get� new data into the system as quickly as it is sent in by cooperators.� Fischer: That is the key. The breeders need all the new information (up to yesterday) at� crossing time--50% of the demand will be during this period.�
Sanchez: What about security?� Corbett: No problem, Paradox allows the files to be easily locked.�

Discussion on the Yield Trial System/� Inte~national Nursery Logistics�
B. Skovmand� Head, Wheat Germplasm Bank�
The present system for managing yield trials, ESCAM, is now outmoded and needs to be replaced. However, development of a new yield trial system is not foreseen until the development of the Data Management System (DMS) is completed. The yield trial system is inflexible in the sense that it is Randomized Complete Block Design (RCB) with number of entries and replications fixed. Further, the system cannot be integrated with our Wheat Pedigree Management System (WPMS), with the result that breeding programs cannot be totally converted.
A small change in program management of the yield trials can minimize the effect of not being able to connect the ESCAM to WPMS. Two types of fieldbooks are being produced in relation to yield trials:
• The actual randomized yield trial.
• A Parcella Chica (PC or small plot) book.
Traditionally, the yield trial books are produced first and the PC books generated from this list, which means that we have to get a list from WPMS, transfer this to the old fieldbook system (FlBGS) and in the end convert the PC list to WPMS. This is cumbersome and time consuming. If the breeding programs were to generate the PC list first and then use this list as input for producing the yield trial list, we could avoid the conversion back to WPMS and ESCAM could be utilized for the time being without causing extra work.
Discussion Notes
Rajaram: In bread wheat, there would be a problem to generate the PC list first.�
Fox: Regarding new experimental designs, the breeders will have to push for these or� there will be no sense of urgency.� DeLacy: Beware of the fact that you may end up with a system that can't handle the new� designs that will be coming along in the next 5-6 years.�
Rajaram: What is the cost of switching from RCB to alpha-lattice?� Fox: Major labor component is adding sticky labels to seed envelopes for the lattice.�
Rajaram: Smaller plots mean at least 15% higher yields and their use may mean we'll� start losing information--especially if there are germination problems like this year.� Jain: In India, we prefer 5 meters because 2.5 meters requires us to hand plant.� Yau: ICARDA, after some discussion, has decided to keep rows at 2.5 meters.� DeLacy: In Australia, we custom fit seed amounts to what cooperators want. This results� in better data, however, trying to fit local designs may be a bit radical for CIMMYT.� Fox: We need a larger sample of cooperator input before we make any changes.� Fischer: Then we need to do a cooperator survey. A concern I have is: are cooperators� following our instructions to trim the edge rows?�
37
Alcala: We sent 7.5 tons of seed to cooperators in 1991-92, averaging 12 grams/envelope...Seed washing for KB currently takes 3.5 months.
Abadalla: What is our current seed washing policy? Fischer: We want to reduce KB teliospores to the lowest level possible. We have extended the policy to Central Mexico. Until we find a location without teliospores in Mexico or can prove that the teliospores do not present a risk, we will have to continue to wash the seed. We are currently installing washing equipment on the International Nurseries bodega roof at El Batan.
Rajaram: 40% of the seed weight is currently with the Yield Trials. For the total weight to remain the same, we must reduce the number of entries and sets if we add any new nurseries.
38�
General Discussion/Conclusions/Actions to Be Taken
Discussion
Rajaram: There is some risk in selecting crossing material from the PYT and YTs...Give� F2s to cooperators who request them, but reserve the right to regulate when necessary� what we give them.�
Fischer: Is there anything to be gained by testing in two locations in the Yaqui Valley?� How well do the artificial environments fit the targeted ones?� Sayre: ENET is a potential data base for determining if more locations in Mexico are� needed.� DeLacy: Before making a change in such <Lsuccessful system, you need the data to show� that a significant improvement is likely.�
Fox: As I understand it, the policy is that the SNs are our major germplasm distribution� tool; the yield nurseries (YNs) for research. The YNs are the only ones that distribute� non-CIMMYT material; could such material be distributed in the SNs?�
van Ginkel: Screening nurseries (SNs) provide the major flow of information for the� crossing programs.� Rajaram: We are looking primarily at disease resistance of ±250 lines; not all that� interested in yield in the SNs.� Delacy: I think that yield data in the SNs are useful and should be recorded even though� 2-row unreplicated.� Singh: I also agree that yield data are useful in the SNs.� Fischer: Looks like there are a number of votes that yield in the SNs is useful.�
Crossa: Suggest going to an alpha lattice design.� Fox: All five YNs will be going to this design soon.� Fischer: What are the additional costs of such a move?� Fox: We'll need some kind of machine to attach the sticky labels...The important thing is� that we must know now if we are to move to lattice for the next cycle as we prepare the� seed shipments� Fischer: Before we decide we need to involve the national programs in the decision.� We've gone long enough without any feedback from them. Perhaps delay the lattice� decision for a year during which time we do cooperator survey.� Fox: National programs are very passive--not all that many complain about any changes� we make. It is almost frightening how cooperators accept the way we do things and the� responsibility implied...However, I believe the lattice design will be an important� technology transfer mechanism for national programs to test their own varieties.� CIMMYT is often the only contact for such technology transfer. Most national programs� are not keeping up with developments in the literature.� Fischer: CIMMYT needs to develop some sort of user-friendly training manual for yield� testing.�
Fox: Perhaps distribute data with seed if DMS turns out to be the efficient and rapid tool� it is purported to be.� Fischer: There is a possibility that too much data will distract our attention.� Fox: Is there a risk in going from three to two reps? We need to decide if we are going to� do it--it will cut the number of envelope by one-third.� DeLacy: More varieties and fewer reps is the way to go for selection. Newer designs� (lattice, AMMI) are more efficient and only require two reps. However, telling� cooperators you are going to two reps is not the same as convincing them.�
39
Gauch: Two vs three reps regarding AMMI: take historical data using two reps and use the third rep to validate.
Workshop Conclusions
Although we have had tremendous impact in the past with the old system, changes are coming. Broad adaptation across several environments will not carry us too much further into the future, especially with shrinking resources. We will be moving to specific environments with more analysis.
Some major points:
• Yield testing within Mexico--no consensus that there be any major changes at the moment. Although we should consider using smaller plots, testing on beds to save resources, and analyzing the ENET.
• Screening nurseries--Consensus that the SNs are important for disease resistance; no consensus on whether yield data are important. Need to look at Australian infonnation on the subject. Need to streamline data collection and speed up its turnaround.
• Yield trials--consensus on the following:
1) Go from three to two reps--notwithstanding the problems in the national� programs.� 2) Do not increase site numbers, perhaps even reduce number of sites due to� the quality of data from certain sites.� 3) Upgrade the statistical analyses (to AMMI, etc.) being used.�
• Infonnation for NARSs--CIMMYT has important technology transfer and training roles. Need to design guidelines for experimental design and yield testing, e.g., include a chapter on biometrics in the Training Manual being put together by Villareal and Rajaram and develop a training manual for yield testing. Need to consult with NARSs on anticipated changes.
• Data Management System--After seeing what can be done during the demonstrations at this workshop, the breeders agree on its value. However, DMS is only part of the challenge--how to extract the wisdom is the rest of the challenge. There is a lot of infonnation on how to do it, but not so much on why to do it.
Specific Actions to Be Taken
The following actions are planned in the near future:
• In 1993-94, ISWYN, ESWYT, EDYT, IDYN, and ITYN will be distributed internationally with two replicates instead of three. This is possible because of gains from the alpha-lattice design. The savings may allow a modest increase in numbers of entries in subsequent years when new protocols for seed washing become routine and automated.
• The CIMMYT Wheat Program and the Biometrics Unit will fund a consultancy to address Spatial Analysis of field experiments and trial design.
40
• The scope of coverage of general nurseries, such as ISWYN, will not change, but others will be more specifically targeted.
• The first product of the Wheat DMS Project will focus on fast feedback to CIMMYT breeders for making crossing decisions.

Appendix i--The Wheat Program's Data Management System (OMS)
P.N. Fox� International Wheat Nurseries�
February 1992�
"What is needed here [nursery reportsJ is the compilation of international trial data in a desktop-computer-database file that can be provided instead of the hardcopy and allow for query and data retrieval according to the user's whims." A. Blum, Volcani Institute.
Introduction
Norman Borlaug once said that international testing "broke down a psychological barrier which had tended to keep the efforts of each wheat researcher isolated. The new testing led to an unexpected acceleration of wheat breeding around the world." This revolution brought about by germplasm sharing will be paralleled by another revolution driven by information exchange and lead by OMS.
Objectives of OMS
A.� To provide a secure, flexible system for the storage of important data on wheat, triticale and barley germplasm.
B.� To provide an integrated set of user-friendly tools for entering, filtering, transforming and accessing data.
Justification
Efficiency, Research, Serving NARSs and Policy Making.
A.� The Wheat Program handles data each year from international trials as well as breeders' trials in Mexico and from activities in laboratories, greenhouses and the Germplasm Bank. Important genetic information is also generated outside of CIMMYT operations. Because much of these data are not stored in an organized fashion, integration of laboratory and field data, for example, is impossible. The increased use of PCS, more decentralized research programs, and personnel changes raise the risk of a fragmented database, part of which may become lost or inaccessible in the future without a more systematic approach to data storage.
B.� Wheat Program scientists require a more accessible database. DMS would furnish convenient read-only data access to program scientists, while . guaranteeing the integrity of the master database.
C.� International trial data coordinated by CIMMYT is under-utilized. Storing agroclimatic and crop management information together with genetic information and plot data will facilitate partitioning and aggregation of data in new and potentially revealing ways.
O.� OMS is viewed as part of a larger system that will include flexible options for trial design, statistical analysis and reporting, and graphic presentation. Together these components will result in more timely and better quality information for CIMMYT scientists and cooperators.

Some History
International nursery bulletins are produced using software written in FORTRAN in the early 1970s, when CIMMYf wheat staff with the computing system division of the RCA company in Mexico City and Dr. Abel Mexas from the Ford Foundation designed and implemented RAPID (Rapid Analysis Program for International Data). Modifications and additions were found to be extremely difficult. However, in 1978-79 LISA (Laboratory for Infonnation Science in Agriculture) from Colorado State University reviewed the system and made some limited modifications to accommodate new requirements of the rapidly expanding testing program. Since that time, the software has been used without significant changes. The resulting software systems (SGYS and SGSS) were never designed as data management tools. Their function was solely generation of international nursery bulletins and they only became a type of default data management system, when the program EXTRACf was written by Neal Bredin to access data from SGYS/SGSS.
. However, data from trials conducted with advanced lines in Mexico, the stage before lines enter international nurseries, are not included. EXTRACf is unwieldy and requires intervention of SCS personnel.
A system for the "corporate data", maize and wheat, was assigned a high priority at a special meeting of the MAC on 12 June 1989.
During 1990, "Data Management System: System Requirements," aimed at a common relational database system for Maize and Wheat was produced.
It was considered by the Wheat Program that, at least initially, agronomic trials would not be considered by DMS. We will prime DMS with international nurseries data, adding data from other field, laboratory and Gennplasm Bank operations later (Appendix 2 covers the status of definition of traits, as well as genetic and environmental descriptors, to be stored or accessed by DMS).
In 1991, a Memorandum of Understanding was signed by the CIMMYf Maize Program and Michigan State University (MSU) for software development. The MSU option was not chosen by the Wheat Program for a number of reasons:
• SCS has delivered the Pedigree Management System (PMS) and has an intimate appreciation of the Wheat Program. By contracting outside, we would lose this considerable in-house expertise, placing all strategic Wheat systems in jeopardy. PMS is the core of the Wheat Program's systems strategy.
• Because of this expertise and the good working relations established between Wheat and SCS, we believe we will get a better return on every dollar invested inhouse compared with outside.
• Problems of communication over distance.
• The Maize Program is seeking much more than a Data Management System. The Wheat Program has many of these additional elements available through PMS.
The Wheat and Maize Programs will remain in contact on the progress of their separate systems. It may prove possible to share certain specific operational functions peripheral to DMS, such as nursery shipment control, automatic generation of phytosanitary certificates and spatial analysis of field trials.
43
Pedigree Management System (PMS)
This section draws from Neal Bredin's "PMS/NWFB Consultancy Report" of December 1990. PMS and associated functions have been developed in SYSTEM 1032 on a VAX computer under the VMS operating system.
The benefits realized via PMS can be attributed to:
• Unique identification of germplasm and
• Accessible pedigree relationships.
Why is unique identification important? If one wishes to share information about something, one has to identify it. Although this sounds simple, it is not always straight forward. Consider how germplasm is identified at CIMMYT. A cross name and selection history constitute primary identifiers. These identifiers are not always unique, the same germplasm may be known by several different names (e.g., VEE#5, KVZ/BUHO/IKAL/BB, CM33027-F-15M-500Y-OM, etc.). It is not obvious that one of these names may be equivalent to another.
This 'failure to associate' is a barrier to effective information sharing. This barrier has prevented the Wheat Program from developing more than a collection of isolated software systems supporting specific tasks. SGYS/SGSS, Breeders Seed Inventory System and the old Field book System (FIBOS) are examples of systems that are self contained, serve a useful function and will never be able to effectively interchange the information they manage.
Information has been managed by how and where it was collected rather than by identifying the germplasm to which it is associated. To illustrate this consider how one would request information about a specific li ne. The questioning procedure in a source oriented system proceeds as follows:
• Which data collection systems record the type of data in which I'm interested (e.g., SGSS, SGYS)?
• Within the confines of that system, which trials (information sources) are potentially interesting?
• Did the line in which I'm interested appear in any of those trials?
Were we to associate information directly to the germplasm to which it relates, the search for information would proceed as follows:
• In what trials (information sources) did the line occur?
• Of these, which are potentially interesting?
In the first scenario, we were faced with the task of reducing the number of places to look even before establishing that the line of interest is in one of those places. Consequently many potential sources of information are overlooked.
In the second scenario, we started from a position of knowing what data were available;� we only had to choose those sources that were potentially interesting.�
44
The data-germplasm association provides a more effective information system than a source-data system. The key to developing a data-germplasm association is the ability to uniquely identify the germplasm:
PMS implements a system to identify germplasm uniquely. The cross identifier (CID) uniquely identifies each cross. The selection identifier (SID) uniquely identifies among the progeny of a cross. Together the CID and SID uniquely identify any germplasm. Already, the 'ability to associate' of PMS has proved a powerful and versatile tool in unexpected areas. For example, the cytoplasmic diversity of CIMMYT bread wheats was examined. From PMS we have the potential to develop a highly integrated data management system, linked to the Wheat Germplasm Bank. DMS will enhance the 'ability to associate', providing the capacity to associate data on germplasm with combinations of latitude, altitude, diseases, country, mega-environment, available moisture and other environmental parameters.
Some examples of what DMS will and won't do
DMS could ask for:
• A list of all sites where international bread wheat, durum wheat and triticale trials have been grown in the same season with less than 350 rom of available water.
• A list of instances where variety X, to be released by a national program, occurs in the database and a second sublist in which all instances of susceptible reactions to five major diseases for the variety are reported.
DMS will not:
• Produce balanced data sets from unbalanced ones, by estimating missing variety by site combinations.
• Provide yield data for all trials sprayed with ILOXAN.
Final Comment
CIMMYT itself must become an exemplary cooperator in the network and take the lead� in returning data.�

Appendix 2--Proposed New Versions orE, GE, and G Data
P.N. Fox� International Wheat Nurseries�
February 1992�
A. General Notes to Be Taken (E Data)
We are asking for more than in the past. We must see the changes from the cooperators' point of view and guard against undue complexity, which could prove counter-productive in efforts to manage data more usefully.
It has been suggested that the proposed detail on water availability is out of proportion with for instance, crop stand where we solicit "poor, fair or good". However, crop stand is also considered as a per plot observation under GE data. Cooperators should also be encouraged to score characters 16 to 21 (below) on a per plot basis when observations are in the moderate to heavy range.
The question of temperature data was raised. Our thinking was that temperature, as opposed to rainfall, is relatively stable across years. Nonetheless, extreme deviations from the norm could be accommodated in 23, a general comment on weather. Screening nurseries may require less ennvironmental data than replicated yield nurseries. There is opportunity to revise these questions.

We do not expect all traits to be recorded by all cooperators. Currently international nursery fieldbooks list the following traits to be recorded: the three rusts, powdery mildew, loose smut, net blotch, scald, BYD, days to heading, height, yield and "others". The current software, Small Grain Yield System (SGYS) and Small Grain Screening System (SGSS) can, however, manipulate 80 fixed traits. Should we remove this biasing factor towards given traits in fieldbooks and stress that cooperators return data on the traits important at their sites? * DENOTES KEY TRAITS.

Key pathological traits have to be defined. Also lacking are transformations for the Modified Cobb Scale and the 00-99 scale. These are required for averaging across replicates and over sites. The 00-99 scale is described in Septoria disease manual (Eyal et al. 1987, page 24). The first digit 0 to 9 is the percent height of the plant, up to where infection has occurred (flag leaf height = 9), and the second digit 0 to 9 estimates the percentage of the foliar area covered with the disease within that height. A new version of "Instructions for the management and reporting of results for the CIMMYT wheat program international nurseries"--including all Latin names for each disease--is required for implementation of DMS.

Appendix 3--1989 Position Paper on CIMMYT International Wheat Nurseries
P.N. Fox� International Wheat Nurseries�
We at CIP learned fast that if we do not gather relevant data to set priorities someone else will gladly assume that role.
--Robert E. Rhoades, Potatoes and Our Fragile Earth
Agroecological Research at CIP
... the panel recommends that: * CIMMYT overhauls its international testing program of nurseries to take better advantage of new technology and trial designs and thus make more relevant the experimental and analytical components of this important effort. Greater economy and efficiency should be possible from the testing programme if it were concentrated in selected sites in each mega-environment. ...
--Report of the third external program review of CIMMYT, 1988.
Aim of this Paper
This document was written in 1989 to provoke, rather than to propose definite solutions and to stimulate thinking on the future use of International Nurseries. Flaws in the system are mentioned only to describe where we are, before addressing where we are going.
Summary
Readers should consider the following points:
• There is danger of throwing away the baby with the bath water in a "key site" approach because the chance of accumulating genes for undiagnosed stresses is minimized. A key site system must complement and link to the existing nursery network. Any initiative involving key sites should strengthen the efficiency and increase the relevance of our major research tool--the current network.
• "Aberrant sites" may be more useful than "key sites", especially when underlying biological explanations for abnormal behavior are revealed.
• Large data sets risk including unreliable sites that are, at worst, random noise. Our experience shows that inclusion of such "unreliable" sites hardly influences across-site analyses of yield data. Discarding such sites, however, may result in the loss of valuable information.
• International nursery yield data are notoriously noisy, but methods, especially the Additive Main Effects and Multiplicative Interactive (AMMI) analysis, are currently being applied to this problem at CIMMYT.
• International yield nursery data are under-rated as a research tool. However, integration of results and feedback to cooperators must be improved. The quality
53�
of the tool will be improved with a data management system and current implementation of more efficient trial designs.
• Any trial design improvements for yield data analysis should have positive spinoffs for disease as well. Analysis of disease data requires in-depth revision and more staff input.
• CIMMYT could become a center of excellence for analysis of large biological data sets. Our comparative advantage is in the huge data bases collected and awaiting analysis, combined with in-house biological experience for interpretation.
• CIMMYT must move rapidly towards giving cooperators the choice of receiving field books on diskette or paper and must be ready to receive data from cooperators on diskette.
• International Nurseries must be linked to the Pedigree Management System (PMS) to take full advantage of its management capabilities and to input valuable information to the proposed and urgently required Data Management System (OMS).
• International nursery bulletins are still produced by software from the early 19708. Bulletin formats desperately need overhauling and the best option appears to be building an interface between OMS and an off-the-shelf statistical package.
• Implementation of the recommendations discussed in this position paper will require a strong and explicit commitment from the Wheat Program and a dynamic Systems and Computing Services (SCS).
Sites, Sacraments, and Serendipity
A science fiction film revolved round the theme of election of the u.S. President. Instead of the unjustifiable expense of today's electoral process, the one person who most closely represented the feeling of the entire U.S. population was identified to individually select the President. Perhaps the theme has elements in common with the "key site" approach to germplasm testing.
It is beyond dispute that CIMMYT's wheat breeding efforts would benefit from more detailed characterization of environments. Judicious selection of sites for this process could form a subset of II key sites" to improve understanding of genotype by environment interaction. However, such a system must complement and link to the ISWYN/ESWYT/lDYN/EDYT/lTYN network so that we know some points in the environmental spectrum covered by international trials with greater accuracy than the remainder of sites. This should facilitate extrapolation, with respect to limiting environmental factors, from key sites to other testing sites. Any "key site" initiative should strengthen the efficiency and increase the relevance of the existing International Nurseries network and not be an independent thrust. Similarly, special research efforts, like the three crop stress trial distributed in 1987, should link to the major network. Unusual results (referred to below in the section on discarding sites from analyses) from the ISWYN21 at Quito were interpretable mainly because an acid soil indicator set of varieties was also sown. This provides an example of the general principle that detailed physiological or environmental observations or special trials and regular international nurseries, should complement each other.
54
Key sites should strengthen the current system's scope and not restrict it. Against a global current of more sites and less replication it appears somewhat ironical that forces seem to be pushing CIMMYT in the opposite direction. Efficiency aside, the potential political repercussions of denying more cooperators yield nurseries cannot be overlooked.
The word "key" has become somewhat emotionally charged in the English language. The media also love this star player of the world of scientific grantsmanship. Once the label is attached, "key" information is superior to other information.
Analysis of scientists' conceptions of what constitutes a key site generally indicates environmental conditions which are stable over years. The factors responsible for discrimination of germplasm are repeatable and thus more readily identified than in highly unpredictable sites. Examples of key sites include:
• CIANO (Mexico) and some locations in the Punjab (India and Pakistan) for yield potential and leaf rust resistance,
• Quito (Ecuador) for stripe rust, and
• Passo Fundo (Brazil) for acid soils.
The information may be no more accurate than from any other site, but interpretation is neater. However, the idea that key sites will provide the same information as extensive wide testing is an illusion in which generally large genotype by site by year interactions are not considered. These interactions may preclude finding key locations for such elusive traits as drought tolerance.
One thrust for moving towards a key site approach may be the fact that we did relatively little that was innovative or adventurous in reporting the huge volume of International Nurseries results to cooperators. At the same time a shotgun distribution approach which served CIMMYT breeders fairly well was not coherently and rationally defended.
Inexplicably, external pressure to reduce the scale of international testing by focusing on "key sites" seems stronger than pressure to use available data more intelligently. Maybe this pressure stems from scientific reductionism which is an approach also commonly used by some nuclear physicists to tackle complex problems in their field. If it is difficult to study complex interactions between subatomic particles, they often decided to take on only one or two dimensions of the problem at a time. As Mitchell J. Feigenbaum said in describing the flaws of such methodology: "There's a fundamental presumption in physics that the way you understand the world is that you understand the stuff that you think is truly fundamental. Then you presume that the other things that you don't understand are details. The assumption is that there are a small number of principles that you can discern by looking at things in their pure state--this is the true analytic notion-and then somehow you put these things together in more complicated ways when you want to solve more dirty problems. If you can. In the end you have to change gears. You have to reassemble how you conceive of the important things that are going on." Is genetics any different? It is relatively straightforward to interpret varietal performance when dominated by reactions to stripe rust, but not as the function of complex interactions between genes for dwarfing, photoperiod, vernalization, undetected soilborne diseases, several foliar diseases and abiotic stresses which occur unpredictably at different stages of the growing cycle.
55
The international testing system is perhaps conceived of, especially with pre-computer thinking, as too large, too random and too difficult to manage. It is true that careful scrutiny of data from five sites is more useful than cursory review of data from 50. So why not just look at a small manageable "key site" data set? This attitude comes through loud and strong in Abraham Blum's book Plant Breeding for Stress Environments. Blum affirms that "while CIMMYT may perform some 90 wheat variety trials throughout the world in 1 year, no one will take seriously a unified biometrical analysis of all these tests." However, it must be acknowledged that at least "Heredity" took one such analysis seriously, with the analysis of ISWYNlO data by Byth et al. becoming a landmark article on multivariate characterization of locations and genotypes. While it is not clear what constitutes a unified biometrical analysis, Blum does have a point about generalization over an extremely large environmental range. However, Byth's pattern analysis approach addresses exactly this point in attempting to subdivide the ecological spectrum into more homogeneous subgroups. Pattern analysis of large data sets may be seen as a tool for generating hypotheses which can be tested, perhaps at key sites using more conventional, and possibly more rigorous, statistics.
A strict "key site" approach to germplasm testing may unwittingly discard screening sites which expose germplasm to unrecognized stresses. Experience with tolerance to two nematode species which attack wheat in Australia is pertinent in this context. Heterodera avenae, the "eelworm" nematode, whose economic implications were almost ignored until the 19705, has probably been in southern Australia since the last century. The variety 'Festiguay' had become popular in some areas of South Australia through its moderate resistance to stem rust during epidemics in 1973 and 1974. When fields cropped to Festiguay in 1974 and 1975 were resown to wheat in 1978 after rotation, spectacular cleaning effects were recognized through failure of the eelworm to reproduce on Festiguay during the previous wheat cycle, reports South Australian breeder Tony Rathjen. The fortuitous resistance of Festiguay to eelworm resulted in this variety representing 50% of grain deliveries to some silos in the early 1980s, despite inherently low yield. It is now believed that eelworm was responsible for average production losses of about 15% in South Australia. CIMMYT lines 'Pitic 62' and 'Mexico 120' both have a high degree of tolerance to this pest. Data presented as examples of intractable genotype x environment interactions were subsequently explainable by tolerance introduced unknowingly to Australian breeding programs in 1963. By 1978 the tolerance was common in advanced lines and is now a feature of some varieties. In the state of Queensland, testing sites which had been regarded as "aberrant" because of their unexplained variability were found to be heavily infested with the nematode Pratylenchus thomei and are now considered important screening sites for the pest. CIMMYT line 'Potam' is a source of tolerance.
An "aberrant site" approach could be the other side of the "key site" coin. Maybe the next breakthroughs will come from "aberrant" rather than "key" sites. The very aberrance may be due to important but still unrecognized factors. It should be underlined that this phenomenon has already occurred for CIMMYT. Before aluminium tolerance was recognized as an important constraint, Passo Fundo appeared to be a miserable location characterIzed by high Coefficients of Variation (CVs) and low heritability. With accumulation of higher levels of aluminium tolerance in the gene pool, it became a key location for screening aluminium tolerance. E.J. Kahn Jr. in The Staffs of Life describes how Portuguese Jesuits persevered with wheat in the highly unfavorable environment of colonial Brazil to produce communion wafers. Today's legacy is a number of key sites and levels of aluminium tolerance which are useful in many parts of the world.
56
Discarding Sites from Analyses
In general for large data sets, the risk of including unreliable sites which are at worst random noise is less than the risk of discarding them. Our experience shows that inclusion of "unreliable" sites barely influences across-site analyses. However, discarding such sites may result in loss of valuable information, once an underlying biological explanation for the abnormal behavior is found. ISWYN21 data from Quito, Ecuador, were nearly excluded from reports, until the differential genotypic response could be associated with soil acidity. CIMMYT Mexico was uneasy with the pattern of yields exemplified by 'Thornbird' and 'Siete Cerros', 5.2 tlha and 37 kg/ha, respectively. At the opposite extreme, New Zealand data have been questioned as being atypically high for Australasia, even though New Zealand held world spring wheat yield records in the 50s.
The examples from New Zealand and Ecuador highlight pitfalls of discarding trials on subjective bases. However, objective methods may cause more problems. The time honored CV, the ratio of the square root of the error mean square to the trial mean, is a poor criterion for discarding trial data. Environments with low yields and large error terms are unduly penalized, although often providing valuable discrimination of germplasm. Disease and other stresses may produce high CVs--and very useful information. For plant breeding purposes, the per experiment heritability or the statistical significance of the genotypic variation is more meaningful than the CV.
The following table provides an extreme example of how genetic parameters may be biased by site selection.
ISWYN 17 No. of sites a 2g
2 age
54 7 46 33* 17 37
* excluding sites from nthn. USA and nthn. Europe
Sites from northern USA and northern Europe may differentiate germplasm in a different manner than sites in developing countries (for which CIMMYT is primarily working). Being generally high yielding and with fewer environmental constraints to differentiate germplasm, these northern sites reduced the apparent genetic variance. They increased the genotype by environment interaction largely by the interaction between those sites as a group ve~us the rest of the world as another group. While this explanation may be debated, the effect of the subdivision on the genetic parameters is irrefutable and alarming.
Trial Design and Analytical Methods for Yield
International yield data are notoriously noisy, but methods, especially AMMI analysis, are currently being applied to this problem at CIMMYT. Other statistical approaches, including Neighbor methods, may also be useful in reducing noise. Generalized Lattices should result in more useful information through greater trial accuracy. For this reason, ITYN21 for 1989/90 was distributed using a Generalized Lattice design and independent randomizations at each location. However, the inflexibility of the existing nursery reporting system will come home to roost with a vengeance when the output from lattice analyses has to be spliced into a bulletin. Immediate decisions have to be taken on such
57�
issues and the policy determined for 1990/91 international yield nurseries. Rowand Column and other designs may be considered in the future.
The recent initiative of ICARDA to improve across-site analysis, using cluster analysis is to be commended. While CIMMYf is considering similar options, we are largely hamstrung by the inflexibility of the processing software for international data. Simple, coherent explanations of newer analytical techniques are essential to make them useful to cooperators. For example, a well-explained dendrogram of inter-site relationships should allow some cooperators to begin to make their own inferences over time about their environment with respect to other regions of the world.
To increase the utility of international nursery data, the question of long term checks should be addressed.
Analysis of Disease Data
Processing and analysis of disease data is complex and trial design improvements should have positive spin-offs for disease screening. As disease notes are to a degree subjective, judgements on cooperators' scoring ability are inevitable and make the issue somewhat delicate. Our ability to analyze disease data lags behind that for yield, but indications are that more filtering and manipulation is needed. Leon van Beuningen's studies on correction of foliar blight scores for height and maturity provide a useful starting point. The Global Disease Monitoring Project will complement this work. The justification for a "key site" approach is stronger for disease screening, where unreliable data are more influential, than for yield.
Biotechnology and Upstream International Nurseries
If biotechnology plays a role in wheat breeding, it will probably have the biggest impact in the highly reliable conditions which characterize "key sites". For instance, known genes to match known environmental conditions could be monitored by RFLP techniques. If this thesis is accepted, it follows that traditional statistically oriented testing should concentrate more on marginal and unpredictable environments at the expense of key sites, which become increasingly the gene jockeys' domain.
In passing upstream, CIMMYf could become a center of excellence for analysis of large biological data sets. Our competitive advantage is in having huge data bases already collected, combined with on-tap biological experience required for interpretation. Computing hardware facilities would generally be sufficient if the current tempo of upgrading were maintained. Maybe the time is now ripe to consider at least Postdoctoral positions in analysis of international wheat data.
The relationship between observed phenotypic diversity for adaptation and its underlying genetic base is largely unexplored, except for more simple examples where adaptation is grossly affected by disease susceptibility. The scope of the CIMMYf testing programme combined with modem cytogenetic and transformation techniques, for single gene insertion, might provide powerful insights.
Germplasm Distribution Mechanism, Research Tool and Catalyst
Norman Borlaug once said that international testing "broke down a psychological barrier which had tended to keep the efforts of each wheat researcher isolated. The new testing led to an unexpected acceleration of wheat breeding around the world."
58
It is perceived that screening nurseries have been a much more potent agent for gennplasm distribution than replicated yield nurseries, which have provided a generally under-rated research tool. Some of the studies which have been conducted largely in isolation are listed below. All but the penultimate were conducted on yield nursery data.

The ISWYN10 study, which suggested a dramatic narrowing in the genetic base since ISWYN4, was not well received by CIMMYT. The authors themselves acknowledge that they perhaps ignored the influence of discarding very poor germplasm between ISWYNs 4 and 10. All parties involved would have benefitted from a more open discussion of the findings.
The research function of yield nurseries will be significantly improved with improved trial design and analyses. However, priority setting will be required to affect such changes and tradeoffs will have to be made. Use of CIMMYT-managed international data by others should be actively encouraged. Slow response to requests for data amounts to passive discouragement. Independent analyses can be safeguards against CIMMYT biases. More importantly, the more heads working on international data the better, and the greater the chance of detecting trends with implications for breeders.
Electronic Media
CIMMYT must move rapidly towards giving cooperators the choice of receiving field books on disk or paper and must be ready to receive data from cooperators on disk. Our more advanced cooperators, who have the greatest capacity to return results of more sophisticated genetic and other analyses, are frustrated by CIMMYT's adherence to the paper medium. The International Nurseries data base should be freely available on COROM to stimulate its use. Because of the size of the data base, other fonns of distribution are unwieldy.
59
Glasnost in Reporting
A degree of "glasnost ll in international nursery reporting should be encouraged. For example, germination problems associated with new seed dressings could be shared openly with cooperators, as could discussion of different sowing rates used by CIMMYT and ICARDA in international testing. Cooperators would also benefit from guidance from CIMMYT for issues such as in which circumstances they might expect problems from sticky dough associated with the 1B/1R translocation.
Bulletin Formats
International nursery bulletins are produced using software written in the early 1970s, when CIMMYT wheat staff with the computing system division of the RCA company in Mexico City and Dr. Abel Mexas from the Ford Foundation designed and implemented RAPID (Rapid Analysis Program for International Data). Modifications and additions were found to be extremely difficult. However, in 1978-79 LISA (Laboratory for Information Science in Agriculture) from Colorado State University reviewed the system and made some limited modifications to accommodate new requirements of the rapidly expanding testing program. Since that time, the software has been used without significant changes. The extremely rapid growth of the nursery network in the 70s precluded detailed attention to the finer points of reporting. The immediate issues were to pack and despatch increasing quantities of seed and to input incoming data, whose growth paralleled the growth in seed tonnage. In 1988, the CIMMYT wheat program shipped 2961 sets of seed.
CIMMYT now suffers some degree of credibility problem from the reporting format. Close cooperators may accept shortcomings, but the wider scientific community will become increasingly critical. It is time for improvements. For example:
• Sometimes, CIMMYT sites do not report sowing and harvest dates as well as other basic information. Immediate attention should be paid to this.
• LSDs and CVs are produced for sites that return unreplicated data.
• Many latitudes are incorrect e.g. 28°N for Cordoba, Spain.
• Correlations greater than one sometimes appear.
• Many small details, in themselves not major, collectively detract from the bulletins. For instance, 'BYD', not 'BYDV', should be used for field symptoms and many place names are misspelled.
One wonders why there is so little reaction from cooperators to less trivial errors. Their silence is worrying and begs the question "Are the reports read?"
The international botanical system for dates, day/month/year with the day and year in arabic numerals and the month in roman numerals, should be considered to avoid confusion between the commonly used date conventions of Latin America and Europe on one hand and USA and Canada on the other.
Refinements in headings of individual location tables could be made. The almost universal "cereal staff' in the tables is not useful. Abbreviations N, P20S and K for fertilizer applications could reduce cluttering, as would a default convention for seasonal
60
conditions (whereby II normal conditions II would disappear from most tables, with only atypical factors reported).
Ancillary Environmental Data
It would be useful to maintain a detailed data base for sites, bringing together many valuable ancillary data, such as soil tests. This would not be published in bulletins, but would be available for research.
The Next Step
The Pedigree Management System (PMS) will become the core of the Wheat Program's computerized plant breeding and germplasm management systems in Mexico. International Nurseries must also be linked to PMS to take full advantage of its management capabilities and to input valuable infonnation to the proposed DMS-envisaged as an extension of PMS. PMS was designed basically to manage the bookkeeping in breeding, but has also shown its worth as a powerful and versatile research tool in unexpected areas. For example, it was determined extremely rapidly using PMS that the majority of CIMMYT bread wheats have one of three dominant cytoplasms.
Of possible strategies for overhauling nursery bulletin format, the best appears to be through an interface from DMS to an off-the-shelf package such as SAS or GENSTAT for bulletin generation. The question is, does CIMMYT have available expertise to implement this option rapidly? The most optimistic estimate is that DMS will be at least one and a half years in development.
It would be fruitful to consider how other international centers handle reporting and analysis of data.

Appendix 4--Survey of CIMMYT Staff on International Nurseries Reporting
In 1989, twenty-one scientific staff--less than 50% of the Wheat Program--responded,� though of these, not all responded to all questions. Eleven replies came from outreach.�
Ql: Is more, or less, information about the origin of entries required, for instance� the name and type of the institution producing each entry?� Four respondents felt that no more infonnation was required, while 13 suggested� additions, the most common being credit for the breeding institution. It was also� suggested that for large countries it is useful to know the region of origin.�
Q2: Is the complete pedigree for all entries required?� YES, 15; NO, 2. '�
Q3: In ISWYN21, one site reported protein and another falling number. Would� more information on quality from the CIMMYT laboratory, for instance� sedimentation values from Obregon and Toluca samples, be useful?� Two thought that more information would not be useful and fourteen thought to the� contrary. However, it was suggested that depending on the heritability of the characters� involved, some parameters might be misleading for certain locations. Two people� suggested that the earlier practice of providing a general description of quality and� agronomic characteristics had been most useful. Greater effort to obtain and compile� more quality data generated by cooperators was advocated. Pigment content, protein� percentage and microsedimentation values for durums should be considered.�
Q4: For whom should CIMMYT be producing nursery reports? Cooperators? The� wider scientific community? CIMMYT staff? Other? Why?� The majority felt we should be addressing principally cooperators and CIMMYT staff.� Six expressed the need also to cover the wider scientific community. Additionally, two� people replied that for targets beyond CIMMYT staff and cooperators, a different� reporting medium should be considered.�
Q5: Do you find them useful?� Thirteen indicated finding the reports useful, while two suggested limited value for� reasons including generally high CVs, inadequate synthesis of data and failure to explain� abnormal yields.�
Q6: Is it necessary to repeat the variety or cross in each table?� YES, 12; NO, 6.�
Q7: Is it necessary to repeat the origin of each entry in each table?� YES, 3; NO, 15.�
Q8: In your opinion which of the variables being returned can be considered as� reliable data and which are unreliable?� This question elicited a strong and useful response. There was general agreement that� much useful data is returned, qualified by the idea that direct measurements were more� reliable than readings, for instance for diseases. Within the disease field, several felt that� rust scores are usually reliable, but foliar blight scores are more doubtful, depending to a� large degree on the cooperators and the representativeness of locations. The need for case� by case evaluation was a common response, with a plea from one staff member for better� communication between International Nurseries and outreach. Two suggested that the� variability of traits should guide us with respect to their utility, although this would be� difficult for unreplicated data. Interestingly, no one stated explicitly that yield data were�
62�
unreliable, although the opinion was expressed that the relative variety yields were more useful than the yields themselves. One reply doubted the utility of yield data from screening nurseries. Another took the ISWYN21 variables and rated days to maturity, stripe rust in the head, lodging %, scab %, falling no., protein %, tan spot and BYD as unreliable. In retrospect, this may have been an easier way for everyone to respond. Other responses supported this reply with respect to maturity and lodging. Careful examination of disease data was recommended as was the recording of the date of observation. One reply suggested that yield components were often badly taken.
Q9: Should we be more discriminating with respect to which data are included in across-site summary statistics? YES, 12; NO, 2. If so, how? This had been handled to a degree in the previous question. Of three suggesting generally more screening of data, one explicitly advocated "pre-screening" in the appropriate outreach offices. Two suggested a minimum level of infection for disease data. LSDs and CVs for yield data were again mentioned twice as was the idea that summaries from a very few sites are a waste. More training of cooperators was mentioned along with tact to avoid offence to cooperators when discarding data.
QI0: Is the information presented at the top of tables for individual locations insufficient, adequate or excessive? The majority opinion (13) was adequate, but some of these were qualified by "adequate if all information supplied correctly" and the question was asked why CIANO and Toluca are generally the worst offenders in this respect. Three suggested that the information was insufficient, in one case in relation to soil fertility and in the others with respect to moisture supply. The necessity for a clear statement of both precipitation and irrigation, preferably including number of irrigations, was highlighted. Otherwise, it appears that Kafr EI Sheikh grew 6 tons of wheat on 52 mm moisture!
Qll: Could the above information (QI0) be presented in another part of the bulletin? YES, 7; YES, BUT INADVISABLE, 2; YES IF COMPRISES SUMMARY ADDITIONAL TO RESULTS PRESENTED FOR EACH SITE, 1; NO, 6.
Q12: Should we solicit data on pH, soil depth and soil texture from cooperators? Eleven replies were in favour of seeking this additional information, with two suggesting that the data might aid in mega-environment definition. One answer suggested that we only solicit such information from reliable cooperators, another suggested key sites only. Adding which chemicals are applied as well as identifying problem weeds was suggested. It was pointed out that the information we may seek is not always available. Three other replies recommended requesting pH, while another favoured soil texture. Three staff felt we should not solicit these data, with one suggesting the effort would better directed to obtaining more important meteorological data.
Q13: Would more across-site statistical analyses be useful? YES, 14; YES BUT ONLY FOR INTERNAL USE, 1; NO, 2. If so, which kind? Why? Five specifically mentioned cluster analysis, usually in the context of grouping like sites and sometimes like genotypes. Others mentioned the need to group like sites without suggesting a method. Some suggested multivariate methods in general. The need to analyze across sites with similar stresses was mentioned along with the necessity for some across-year analysis. Three indicated that stability analyses should be employed. Some felt that across-region analyses would be useful, while others expressed
63
reservations about the present regional groupings and the use of clustering was advocated� to derive biologically meaningful site groups, for which different gene pools could be� developed. One suggested weighting sites by their error terms before clustering. Parallel� analyses across regions and also across mega-environments was suggested. Identification� of key sites was given as a goal of across-site analysis. One reply specifically drew� attention to the need for more across-site analysis for disease data.�
Q14: Would more within-site statistical analyses be useful?� YES, 8; NO, 7.� If so, which kind? Why?� Suggestions embrace better qualitative and quantitative description of disease� development, broad sense heritabilities, a 7 x 7 lattice design for the ISWYN, more� attention to randomization to overcome interplot interference and presentation of yields� as percent of the top yield and percent of local check.� Should the local check and check varieties of other species be included in the� analyses?� YES, 3; NO, 2; SAME SPECIES YES & OTHERS NO, 2. One reply also indicated that� other species should not be included in the analyses of variance, but yield could be� expressed as a percentage of other species when they represent the top yield. One reply� questioned the practice of including more than one species in a trial.�
Q15: Are the correlations presented for each location useful and valid?� YES, 4; NO, 3; DOUBTFUL, 5; IF DATA GOOD CORRELATIONS USEFUL, 2. One� of these last two replies included the comment that correlations should not be presented� automatically and especially not when there a large number of missing or zero values.�
Q16: Are the regional summary tables useful?� YES, 12; NO, 2; BETTER DEFINITION REQUIRED, 3 (2 SUGGESTING MEGA�ENVIRONMENTS). Many replies referred to question 13.�
Q17: Should we differentiate individual location tables, regional summaries and� overall summaries using different colored paper?� YES, 7; NO, 8; IF INEXPENSIVE, 4.�
Q18: With increasing mechanization, will we, or should we, have to prepare seed for cooperators who wish to sow non-standard plot lengths? YES, 6; NO, 10. One reply suggested that we supply the amount of seed for each entry that the cooperator requires along with empty sets of envelopes for sowing. Another had serious doubts concerning edge effects and our standard yield plot.
Q19: Any other specific comments on entries, layout or analyses?* Include more basic information such as quality characteristics, Rht genes and�
resistance genes for entries.� * CVs are too high. Can we use Nearest Neighbor analyses? * CIMMYT managed locations should be exemplary, not the least well documented. * Large tables should be laser printed for better reproduction. * Some disease scales need modification. * Indicate which lines are not significantly different from the top yielder. * Implement new designs such as Nearest Neighbor and lattices. * Plot yields of each entry across locations. * Make more use of ranking, as in ICARDA reports. * Produce bulletins faster to increase their utility.
64
Q20: BROADER ISSUES RAISED FOR INPUT. We suggest that there is a fundamental conflict between producing rapid superficial analyses for mass circulation and answering more detailed questions relating to CIMMYT's breeding and selection methodology.
Currently international nurseries fulfill two quite separate functions, namely to distribute germplasm worldwide and to obtain yield, agronomic and disease data for feedback to CIMMYT. The reliability of data and the question of whether the two functions in one trial are compatible should be addressed.
There is a trade-otT to be examined between large global data sets with little reliable environmental data and detailed yield, disease and physical data collection at key locations where more sophisticated experimental design may be feasible.
It was suggested that: * analysis of key locations and the broader data set is quite feasible. Better analysis
will serve both goals as well as widen the audience range. * The ISWYN be discontinued and the IBWSN improved with a subset of entries
maintained for three years. Base staff to brainstorm the question and advise outreach.
* More discussion is needed. * ISWYN could be upgraded and distributed to "good" or "useful" locations, with
germplasm dissemination left to screening nurseries. * Data returned is better than 10 years ago. * Questions related to CIMMYT's methodology are not relevant for bulletins. * International Nurseries staff should know "mega-environments", stations and�
statistical procedures.� * Key locations can grow special as well as general trials. More sophisticated testing
should be conducted in addition to, not instead of, routine testing. * Rapidly disseminated data can also be more exhaustively analyzed for�
methodological purposes.� * Meteorological and disease data must be improved. * Additional data from mega-environments using (specially?) selected germplasm is
required.* ISWYN is useful for initial observations, but special material and areas selected for
CIMMYT long range breeding strategy are needed. * Multivariate analyses of both physical and biological data are required to�
characterize test sites and mega-environments.�

B. CIMMYT Wheat Program Cooperating Locations, March 1992
The list of cooperating locations beginning on page 71 uses country abbreviations accepted by the ISO system. The list represents CIMMYT's first attempts to convert the old location system file (COOP.LIS) to a new sortable system that refers to geographic locations alone without considering management factors and other location descriptions. Such information, however, will be linked to location codes in DMS (e.g., see Table 1 on page 13).
The first digit indicates one of six major world zones. Together, the first three digits uniquely indentify countries. The fourth and fifth digits then identify locations, defined by latitude and longitude, within countries.
Duplication and errors remain. Please advise the first named editor of errors. Please supply the complete record as it appears in the list and then how it should appear. We would also greatly appreciate hearing of the multiple station numbers that refer to what should be considered one single location.
