BOSTICK, LARRY W. WELLS, and BRIAN E. GAMBLE1 Introduction The number of peanut varieties available to Alabama growers has increased in recent years, thus placing greater need for unbiased performance data regarding varietal selection for production. Production and Discussion The 2004 tests were conducted at the Wiregrass Research and Extension Center in Headland, AL. Prior to 2000, comparisons were made only under irrigation. During 2004, 22 entries were evaluated under irrigation, 15 entries were evaluated dryland, and 10 entries were evaluated late-planted dryland. The experimental design for each test was a randomized complete block consisting of two-row plots, 20 feet long, replicated four times. The irrigated and dryland tests were planted on May 11. The late-planted dryland test was planted on June 23. All tests were planted with a cone planter at a rate of six seed per foot of row. Recommended agronomic practices were followed regarding fertility, disease, insect, and weed control in all tests. The irrigated test entries considered to be earlier than Florunner in maturity were dug on September 10. These entries included Andru II, Exp 215, and NC 7. All other entries were dug on September 21, except Georgia-02C (October 1), Tifrunner, C-99R, DP-1, Georgia01R, and Hull, which are considered later than Florunner and were dug on October 7. The dryland test entries considered to be earlier than Florunner were dug on September 10. These entries included Andru II and Exp 215. All other entries were dug on September 21, except Georgia-02C (October 1), Tifrunner, C-99, DP-1, and Georgia-01R, which are considered later than Florunner and were dug on October 7. In the late-planted dryland test, all entries were dug on November 5. Information concerning relative maturity for all test entries was provided by the plant breeder responsible for developing the variety. The information presented here represents data from three years at one location. Yield and disease occurrence data have been subjected to an analysis of variance. This statistical evaluation determined the overall averages for all varieties, coefficient of variation (CV) and the least significant differences (LSD). The LSD values represent the difference required for the averages of two varieties to be considered statistically different. The (.05) following the LSD value indicates that the LSD was calculated at the 95 percent level of confidence. The CV, which is expressed as a percentage, is a relative measure of variation within a set of data. CV values of 8-12 percent are generally considered acceptable for yield data of Bostick is an adjunct professor of the Auburn University Department of Agronomy and Soils and executive vice president of the Alabama Crop Improvement Association; Wells is superintendent and Gamble is associate superintendent of the Wiregrass Research and Extension Center. 1 5 agronomic crops. CV values in the disease data are considerably higher than this. However, this is expected due to random occurrence of disease in the field. Size and Grade Data Terms Data were collected and averaged on samples from replicates II, III, and IV for size and grade. The samples were graded following Federal-State Inspection Service procedures for grading farmer-stock peanuts. Terms Used SMKRS count/lb. (number per pound of sound mature kernels riding screen)—Number of sound whole mature kernels from 1 pound of the shelled sample riding a 15/64 x 1-inch slotted screen or a 16/64 x 3/4-inch slotted screen for Virginia or Runner varieties, respectively. Pct. SMKRS (sound mature kernels riding screen)—Portion of shelled sample as described above. Pct. SS (sound splits)—Portion of shelled sample split or broken but not damaged. Pct. TSMK (total sound mature kernels)—Portion of the shelled sample comprised of sound mature kernels plus sound splits. Pct. OK (other kernels)—Kernels that pass through a 15/64 x 1-inch slotted screen or 16/64 x 3/4-inch slotted screen for Virginia or Runner varieties, respectively. Pct. DK (damaged kernels)—Kernels that are moldy, decayed, affected by insects or weather conditions resulting in seed coat or cotyledon discoloration or deterioration. Pct. TK (total kernels)—All shelled sample kernels including TSMK, OK, and DK. Pct. Hulls —All hulls from the shelled sample. +21.0 (Generally considered as the Jumbo commercial grade)—Portion of SMKRS riding a 21/64 x 3/4-inch slotted screen. -21.0 + 18.0 (Generally considered as the Medium commercial grade)—Portion of the SMKRS falling through a 21/64 x 3/4-inch slotted screen and riding a 18/64 x 3/4-inch slotted screen. -18.0 + 16.0 (Generally considered as the No.1 commercial grade)—Portion of the SMKRS falling through a 18/64 x 3/4-inch slotted screen and riding a 16/64 x 3/4-inch slotted screen.

This line carries the high oleic trait and resistance to tomato spotted wilt virus. Exp. 3081B; 9. Exp. 3085A Advanced breeding lines developed by Dr. Ernest Harvey, Golden Peanut Company. These lines are similar to GK7 in growth habit with medium (135-140 days) maturity. Seed and pod size are also similar to GK7. They carry resistance to tomato spotted wilt virus and late leaf-spot. The high oleic trait is carried by 3085A. 10. Georgia-01R Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released under the 1994 Amendment of the Plant Variety Protection Act. Late maturity range with mid-oleic/linoleic fatty acid ratio with seed and pod size similar to C-99R. Resistant to tomato spotted wilt virus and carries tolerance to leaf spot and white mold. Observations have indicated less occurrence of cylindrocladium black rot and leafhopper damage than with more susceptible varieties. 11. Georgia-02C Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Maturity range medium but probably 7 to 10 days later than Florunner with seed and pod size slightly larger than Florunner. High oleic/linoleic fatty acid ratio with runner growth habit and vine growth more consistent with Florunner than Georgia Green. Resistant to tomato spotted wilt virus and cylindrocladium black rot. 12. Georgia-03L Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released under the 1994 amendment of the Plant Variety Protection Act. Mid-maturity range with normal oleic/linoleic fatty acid ratio with significantly larger pod and seed size than Georgia Green. Georgia-03L carries a high level of resistance to tomato spotted wilt virus and moderate resistance to white mold and CBR. Intermediate runner growth habit with pink seed coat color. 8. 13. Georgia Green Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released in 1995 and protected under the 1994 Amendment of the Plant Variety Protection Act. Same maturity range as Florunner with seed and pod size similar to or slightly more round than Florunner. Normal oleic/linoleic fatty acid ratio with intermediate growth habit and typically less vine growth than Florunner. Resistant to tomato spotted wilt virus, but carries no known insect resistance. 23 14. Georgia Hi-O/L Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released in 1999 under the 1994 Amendment of the Plant Variety Protection Act. Same maturity range as Florunner with larger seed and pod size, high oleic/linoleic acid ratio, and intermediate growth habit. Resistant to tomato spotted wilt virus. 15. Gregory Developed by Dr. Tom Isleib, North Carolina Agricultural Research Service. Released in 1997 under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is earlier than NC 7 with larger seed and pod size. Has normal oleic/linoleic fatty acid ratio and intermediate growth habit. The only known resistances of Gregory are to CBR (this is very slight: i.e., it is less susceptible than NC 7) and to tomato spotted wilt virus (6.5% infection rate compared with 9.2% for NC-V11). Like NC 7 and NC 12C, Gregory is extremely susceptible to sclerotinia blight. Gregory has a pink seed coat. Hull Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. Also carries a patent on the high oleic trait prohibiting non-licensed parties from saving seed for replanting. Hull is a later maturity (150+days) jumbo-runner seed-size, high oleic cultivar with multiple disease resistances. Hull has resistance to tomato spotted wilt virus and late leaf spot similar to C-99R (better than Georgia Green). It has white mold resistance equal to or better than C-99R (better than Georgia Green). Good resistance to cylindrocladium black rot and some root knot nematode resistance. Seed size is similar to C-99R, with somewhat less vine growth. 17. NC 7 Developed by North Carolina Agricultural Research Service. Released in 1978 and protected under the Plant Variety Protection Act. Has become the industry standard for Virginia variety development comparisons as Florunner has for Runner varieties. Maturity range is early compared with other Virginia varieties. Has normal oleic/linoleic fatty acid ratio and intermediate growth habit. Highly susceptible to early leafspot, CBR, and sclerotinia blight but has moderate tolerance to tomato spotted wilt virus. No known insect resistance. 18. NC-V11 Developed by North Carolina Agricultural Research Service, Virginia Agricultural Experiment Station, and USDA-ARS. Released in 1998 and protected under the Plant Variety Protection Act. Maturity range same as NC 7 with smaller seed and pod size, normal oleic/linoleic fatty acid ratio, and runner growth habit.
