Improved peanut varieties on horizon

Several new peanut varieties have been developed recently for the Southeastern market. Seed for these varieties will be very limited or not available for the 2007 production season.

For the University of Florida varieties, the first foundation seed was produced in 2006, and the first registered seed production will occur this year, so seed will be available on a limited basis beginning in 2008.

McCloud (tested as UF03326) is a University of Florida medium-maturity (135-day range) runner market-type release with a runner growth habit. It has shown good to excellent pod yields in Florida and other state tests with excellent grades. Seed of McCloud is larger than Georgia Green or ANorden. It has good resistance to tomato spotted wilt virus and is similar to Georgia Green in its resistance to other diseases. This peanut has high oleic (80-percent) oil chemistry. Flavor, blanching and processing traits are good to excellent.

Florida-07 (tested as UF04327) is a University of Florida medium-late (140-day range) runner market-type peanut with runner growth habit. It has shown excellent yield potential (7,000-plus pounds per acre) with good grades. Seed of Florida-07 is similar in size to C-99R and for this reason, gypsum is recommended. It has good to excellent resistance to tomato spotted wilt virus with some white mold resistance. It also has tolerance to leafspot. Florida-07 has high oleic (80-percent) oil chemistry with good to excellent roasting, blanching and processing characteristics.

York (tested as UF04321) is a University of Florida late-maturity (150 days) runner-type peanut with excellent yield potential and good grades. Seed size is similar to Georgia Green. It has excellent disease resistance to tomato spotted wilt virus, white mold and leafspot. The leafspot resistance of York is good enough to allow a reduction in fungicide sprays in a good rotation, and its white mold resistance is among the best available. York has high oleic (80-percent) oil chemistry with excellent flavor and processing traits.

AT-3081R is a new commercial release from AgraTech/Golden Peanut Company. This runner-type peanut has a 130 to 140-day maturity range in the Southeast. AT-3081R has high yield and grade potential and a spreading growth habit with a distinct main stem during the growing season. Seed size is similar to C-99R. This variety has excellent seedling emergence and seedling vigor. It also has excellent resistance to tomato spotted wilt virus.

Attaboy is a new, multiple pest-resistant, runner-type peanut variety planned for joint release in 2007 by the Georgia Agricultural Experiment Station and the United States Department of Agriculture. It is a composite of two sister lines. Attaboy is a late-maturity variety — 10 to 14 days later than Georgia Green and similar to C-99R in maturity range. It has resistance to tomato spotted wilt virus that is similar to C-99R and leafspot resistance similar to Georgia-01R. In addition, it has resistance to leaf hoppers, white mold resistance similar to Georgia-01R, and three-cornered alfalfa hopper resistance similar to AP-3. Attaboy has good yield stability across environments in the Southeast and performs well under conditions with reduced inputs relative to foliar diseases.

Georgia-05E is a new Virginia-type cultivar release from the University of Georgia. It has the best level of resistance to tomato spotted wilt virus of all Virginia-type cultivars. Maturity is slightly later than Georgia Green and it has high-oleic chemistry. Seed supply will be very limited in 2007.
