SUMMARY. Databases are commonly used to coordinate and summarize researchfrom multiple projects. The potato (Solan urn tuberosurn) research community hasinvested significant resources in collecting data from multiple states and provinces,and we have developed a web-based database format for the use of researchers,farmers, and consumers. The northeast regional potato variety development project(NE1031) is a U.S. Department of Agriculture, Cooperative State Research,Education, and Extension Service (USDA-CSREES) regional project focused ondeveloping and evaluating the suitability of new varieties and advanced clones frommultiple breeding programs for a range of environments. This multistate projectand its predecessors have been in existence for more than two decades, and they haveresulted in the collection of a significant amount of standardized potato trial data.We have developed an interactive potato variety database that allows researchers andend-users to access and obtain potato variety trial results in one centralized site. Thedatabase is populated with the results of potato variety trials conducted in eightstates (Florida, Maine, New Jersey, New York, North Carolina, Ohio, Pennsylvania,and Virginia) and two Canadian provinces (Prince Edward Island and Quebec).It currently contains over 35 data features and was developed primarily forscientists interested in potato variety development, growers, and allied industrymembers. Hypertext mark-up language (HTML) and hypertext preprocessor(PHP) were used to develop the database interface.
T
lie USDA-CSREES NE1031project entitled "Develop-ment of New Potato Clones
for Improved Pest Resistance, Mar-ketability, and Sustainahi]iry in theEast" is a project that addresses theneeds of the potato industry ofthe eastern United States througha coordinated process of potatobreeding, selection, evaluation, andvariety development. Potato breedingand gerniplasm improvement in this
Canada. The overall goal of the projectis to develop an array of attractive,nutritious, high- yielding, disease- andinsect-resistant potato varieties thatcan be emplo yed by small and largepotato producers to enhance market-ing opportunities, farm sustainabilitv,and grower profits.
Breeding, selection, and develop-ment of adapted, chipping, French fry,specialty-type, and fresh market varie-ties are emphasized in this project.Selection procedures for processinglines emphasize high dry matter, ac-ceptable fm-v color, and freedom frominternal defects. Fresh market selec-tion and evaluation emphasize excel-lent appearance, sensory, andnutritional qualities. Development ofvarieties with durable, multiple resis-tances to important pathogens andpests, such as late blight (Phvtoplithoi-tiinfestruis), verticilliuni wilt ( Verticil-hum dabltae), earl y blight (Altcrnaricjso/an i), common scab (Strcptomyce.cSlap.), Fusarium dry rot (Fusariu;nspp.), golden nematode (Hctcrodcrarostochiensis), and colorado potatobeetle (Leptinotarci-i decemhincata) re-sistance are long-term priorities.
The NE1031 project is highlycollaborative and takes advantageof' the multiple potato breedingand variety development programslocated in the eastern United States.The project has established a mecha-nism for sharing and exchanginggermpl asm and research results be-tween eight participating states andtwo Canadian provinces. To ficilitateeasy access of key information, wehave developed a web-based, user-friendl y potato variety database tofacilitate data management and accessfor the NEI 031 project and the entirepotato research community . This va-rictv database site was designed pri-manl y with the interests and needs ofthe potato research community inmind, but it can be accessed easilyby farmers, seed brokers, and homegardeners interested in obtainingtimel y information on regionalregional po-tato performance. The primary goalwhen constructing the database wasto condense and distill the manyvariety trials that the NE103I projectconducts into a format that was Stan-dardized for key data, such as totaland marketable yield, tuber appear-ance, plant maturit y, and specificgravity . However, it was also designedto store unique data collected by
project arc conducted by four potatobreeding programs (University ofMaine, Cornell University, North (,ar-olina State University, and USDA-Ag-ricultural Research Service- Bcltsville,MD). Earl y generation multisite selec-tion, subsequent advanced clone eval-uations, and variety trialing are thencoordinated across eight eastern states,with collaborative research effortsextending to trial cooperators acrossthe United States and into eastern

Materials and methodsDATABASE DESIGN. The database
runs on a Mac OS X Server (version10.4.10; Apple Computers, Cuper-tino, CA) with a dual 2.7 GHzPowerPC CS processor. This isa stand-alone server located atNCSU, VGJREC. The data are sub-mitted by collaborators in Excel(Microsoft, Redmond, WA) spread-sheet format (Fig. 1) and convertedinto two text files where various char-acters are used to delimit clones andclone elements (Figs. 2 and 3). Theclone elements consist of descriptorssuch as year, trial, and trial location,and data specific to the performanceof a clone. Using the Terminal soft-ware package provided on the MacOS X Server, the elements of the twotext files are imported into tables ina format recognized by MvSQI.®(MvSQL®, Cupertino, CA), whichis an open source relational data-base management system based onstructured query language (SQL)(Techlerms.com , 2007). A relationaldatabase is a collection of tables thatrefer to each other through a commonset of parameters identified in eachtable (Meloni, 2002). In the easternpotato variety development database,
we chose to have three sets of com-mon data elements consisting ofa combination of five specific ele-ments. These elements consist ofthe variety name (or clone number),the state (or province), the county,the trial designation, and the year. Forexample, the first identifier containsall five data points, the second consistsof the variety, trial designation, andyear, and the final has only the varietyand year. The purpose of havingmultiple identifiers is to allow dataretrieval at varying levels ofspecificitv.Data points related to specific loca-tions not collected by each coopera-tor are handled easily by theMvSQL® engine provided if themissing data are coded as missingand not zeros. When calculating anaverage, it will ignore all data that hasa "." in place of the data point. Alldata are encapsulated in quotationmarks (" "), fields arc delimited bythe vertical bar character (1), and theend of an entry is denoted by threecolons ( :::). The preceding delimitersused for coding are arbitrarily desig-nated by the administrator and aredictated to the processor to define thedata points. Each of the files is alsocoded with the statement: NOWO,two times at the head of the entry.The NOW() statement is an SQLderived command that dates each
entry . The first statement stamps thedate of upload to the database, theother records the last date the entrywas altered.
INTERNET INTERFACE DESIGN.
The original interface for theNE 1031 eastern potato variety de-velopment database was patternedafter a database developed b y S.R.James (Oregon State Universit y ) thatused HTML coding. This site is nolonger operational. To make a moreuser-friendl y interface, we migratedto a combination of PHP and HTMLweb programming, which allowsusers to more narrowl y define theavailable list of varieties and advancedlines. The web interface allows visitorsto limit performance of searches byvariety release status, tuber color, andor plant maturity. Any combinationof these three traits can be used tolimit the output of lines displayedfor each search. Our latest designchanges have also incorporated a stan-dardized layout using Dreamveaver(version 8.0; Macromedia, San Fran-cisco, CA), giving the vebsite a moreprofessional appearance.
After a user decides which typeof clones he/she is interested in (e.g.,by tuber color: red, white, purple,and/or by maturity : early, midseason,late), the list is reduced to a specific setof clones, and the output can then be

further constrained by selecting loca-tions, traits, and years of interest (Fig.4). Before clicking the submit button,the user can also choose how the dataare sorted and the formatting of thesummaries printed. The output is pre-sented in a tabular form and is expressedusing PHP and HTML (Fig. 5).
A second interface was con-structed to allow users to builda one-page summary (Fig. 6) to com-pare a variety of interest with
a standard variety that can also beselected by the user. The summaryincludes yield, color, maturity , chip-ping scores, intended use, and knowndisease, insect, and virus resistances. Ifavailable, an image of the variety isshown on the summary.
Results and discussionTo date, individuals from 26
countries, five continents, 26
American states, and live Canadianprovinces have used the database.The average length of visit is between1 and 2 mm, and the longest hit lasted62 mm (ActiveMeter, Calgary , AB,Canada). The database users havebeen diverse, ranging from govern-ment agencies and universities togrowers and individuals from urbanareas.
Future improvements for the da-tabase include building another

interface that will allow the compari-son of multiple varieties for a set ofuser-defined parameters. New fea-tures will be added to the existinginterfaces to allow a user to search forvarieties with resistance to specificvirus, bacterial, fungal, and/or insectpests. This will increase the overallusefulness of the database.
The utilitvofthe NE1031 easternpotato variety development databasehas lead to some discussion regardingthe development of a national or
North American potato variety trialdatabase. This is a good goal; however,a major impediment to implementingsuch a resource relates to the diverse setof evaluation criteria collected by theindividual potato research groups andregions across the country. One of thekey factors enabling the developmentofthe NE 1031 potato variety databasewas that all regional potato coopera-tors agreed to evaluate our materialsusing a standardized set of evaluationdescriptors.
