Publication Number 436-417, Posted March 2002
One new variety will be commercially available to tobacco producers in 2002. NC 5 met the chemical and physical standards in the 1999 Regional Variety Evaluation Program. Growers are advised to plant only a limited acreage of any new variety until more information and experience is available from a wider range of soil and climatic conditions.
NC 5 (tested as NC 9806) was developed by North Carolina State University. It is a moderately yielding hybrid with resistance to tobacco mosaic virus, the virus complex (potato virus Y, tobacco etch virus, and tobacco vein mottling virus), wildfire, and root knot nematode. NC 5 has a high level of resistance to black root rot. It has a high level of resistance to race 0 black shank and a low to moderate level of resistance to race 1 black shank. Seed will be available from F. W. Rickard Seed Company.
Information is provided for widely grown and recently released varieties in Tables 1 to 4 of this publication. Average performance of twelve varieties in the 2001 Virginia Official Variety Tests (OVT) is shown in Table 1. These tests were conducted in Washington (B. Miller, Jr. farm, industrial park, and Southwest Virginia Agricultural Research and Extension Center) and Lee (H. Scott farm) 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 burley tobacco 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. Where available, averages that include 1997 to 2001 data are also presented in Table 2. Do not compare the average yield of varieties unless each variety was grown the same number of years.
Information on agronomic performance and disease resistance levels is given in Table 3. In addition to yield, quality potential, and ease of handling, the history of various disease problems on your farm should weigh into the decision of which variety is best suited to your production system. Varietal resistance alone cannot prevent losses to diseases. Any variety may suffer damage when disease causing organisms are present and when weather conditions favor their development. An effective pest management program will also include crop rotation and other cultural control practices. Combining varietal resistance with crop rotation, early root destruction, and proper use of labeled pesticides is the only way to achieve consistent, cost-effective pest control.
