Extension Tobacco

Flue-Cured Tobacco Variety Information for 2000

C. A. Wilkinson, T. D. Reed, C. S. Johnson, and J. L. Jones*

Seed of five new varieties will be available to tobacco producers in 2000. OX 414 NF and Sp. G-179 met the chemical and physical standards established by the Regional Variety Evaluation Committee in 1997. Both raw and pelleted seed of these two varieties will be available. RG H51, PVH03, and PVH09 met the standards in 1998, are male sterile hybrids, and only pelleted seed will be available. Information on parents used to develop a hybrid is not released. All five new varieties are resistant to the common races of the root knot nematode. OX 414 NF, Sp. G-179, and RG H51 are susceptible to tobacco mosaic virus whereas PVH03 and PVH09 are resistant to tobacco mosaic virus. Growers should consider planting a limited acreage of any new variety until more information and experience is available from a wider range of soil and climatic conditions.

OX 414 NF (tested as OX 4142 NF) was developed by North Carolina State University from a cross of NC 37 NF x K 346. Seed will be available from RG Seed Company. OX 414 NF is a non-flowering variety whose yield is similar to NC 27 NF and greater than NC 37 NF. It has a moderate level of resistance to black shank and a low level of resistance to Granville wilt.

Sp. G-179 (tested as Speight 179) was developed by Speight Seed Farms from a cross of Coker 371 Gold x Sp. G-28. Sp. G-179 has a field type similar to Sp. G-28. It has a very high level of resistance to black shank and a high level of resistance to Granville wilt.

RG HSI (tested as RGSH-17) was developed by RG Seed Company. Seed will be available from F. W. Rickard Seed Company. RG H51 is a moderate yielding hybrid with good quality. It has a very high level of resistance to black shank and a low level of resistance to Granville wilt.

PVH03 (tested· as PVH03) and PVH09 (tested as PVH09) were developed by Profigen Inc. Seed will be produced and marketed by F. W. Rickard Seed Co. under the RG Seed Co. label. Both are moderate yielding. PVH03 has a low level of resistance to black shank and Granville wilt. PVH09 has a low level of resistance to black shank and a high level of resistance to Granville wilt.

Information is provided for widely grown and recently released varieties in Tables 1 to 5 of this publication. Results of fourteen varieties included in the 1999 Virginia Official Variety Tests (OVT) are shown in Table 1. These tests were conducted in Charlotte (Jamie Newcomb), Halifax (Wayne Palmer), Pittsylvania (Kevin Motley), and Nottoway (Southern Piedmont Agricultural Research and Extension Center) counties under the joint supervision of Extension Agents in the respective counties and Virginia Polytechnic Institute and State University research and Extension personnel. Testing in various locations throughout the production area makes it possible to evaluate varietal performance under the widely ranging soil and weather conditions existing in Virginia. Such a testing program also provides an opportunity for producers to observe different varieties under field conditions in their particular region. Contact the Extension agent in your county to arrange a visit to the on-farm variety test nearest you and to learn of tours of tobacco on-farm tests.

Data in Table 1 are for only one year and the results may not be indicative of what might be obtained in other years. There was some differential leaf drop among varieties in 1996 due to Hurricane Fran~ therefore, yield data from 1996 needs to be interpreted cautiously. Where available,

1 Harvest date for each priming was determined by the appearance of the tobacco at each location. The tobacco produced and the rate of removal were influenced by individual management and local soil and water conditions. 11

averages that include 1995 to 1999 data are also presented in Table 2.

Information on agronomic performance and disease resistance levels is given in Table 3. The use of disease resistant varieties is a very effective means of reducing losses due to certain diseases and nematodes. However, varietal resistance cannot be used alone. Any variety may suffer damage when nematodes and disease causing

organisms are present and when weather conditions favor their development. An effective pest management program will also include crop rotation (particularly with fescue and small grains) and other cultural control practices. Combining varietal resistance with crop rotation, early stalk and root destruction, and proper use of pesticides is the only way to achieve consistent, cost­effective disease and nematode control.
