The 1999 Alabama Performance Comparison of PeanutVarieties James P. Bostick, Larry W. Wells, and Brian E. Gamble' 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 The 1999 test was conducted at the Wiregrass Research and Extension Center in Headland, Alabama. The experi- mental design was a randomized complete block consisting of two-row plots, 20 feet long, replicated four times. The test was planted on May 4, 1999, 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. The test was conducted under irrigation. Entries considered to be earlier than Florunner in maturity were dug on September 3, 1999. These entries in- cluded AgraTech 1-1, AgraTech VC 2, Andru 93, NC 7, VA 93B, VA 92R, and ViruGard. All other entries except Southern Runner and Florida C99R were dug on September 14, 1999. Southern Runner and Florida C99R, consid- ered to be later in maturity, were dug on September 29, 1999. Information concerning relative maturity was provided by the plant breeder responsible for developing the variety. DISCUSSION The information presented here represents data from three years at a single location. Performance comparisons among varieties should be drawn judiciously under these circumstances. Yield and disease occurrence data have been subjected to an analysis of variance. This statistical evaluation determined the overall averages for all varieties, coef- ficient of variation (CV), and the least significant differences (LSD). The LSD values represent the difference re- quired 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 to 12 percent are generally considered acceptable for yield data of 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. 'Bostick is an adjunct professor of the Auburn University Department of Agronomy and Soils and executive secretary of the Alabama Crop Improvement Association; Wells is superintendent and Gamble is assistant superintendent of the Wiregrass Research and Extension Center. 2 ALABAMA AGRICULTURAL EXPERIMENT STATION Terms Used g/1100 SMKRS (grams per 100 sound mature kernels riding screen)-Weight in grams of 100 sound whole mature kernels from the shelled sample riding a 15/64 x 1-inch screen or a 16/64 x 3/4-inch slotted screen for Virginia or Runner varieties, respectively.

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. ACKNOWLEDGMENTS The authors express appreciation to Austin K. Hagan, Professor of Entomology and Plant Pathology, for provid- ing the disease evaluation data and to Glenn Wehtje, Professor of Agronomy and Soils, for the statistical analysis.

Released in 1997 with plant variety protection applied for 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. 12 ALABAMA AGRICULTURAL EXPERIMENT STATION 1999 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES 16. NC 7 Developed by North Carolina Agricultural Research Service. Released in 1978 and protected under the 1994 Amendment of 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. It is preferred for the in-shell export market due to its large pod and size. 17. NC 12C Developed by North Carolina Agricultural Research Service. Released in 1996 and protected under the 1994 Amend- ment of the Plant Variety Protection Act. Same maturity group as NC 7 with about the same seed and pod size, normal oleic/ linoleic fatty acid ratio, and intermediate growth habit. Intermediate resistance to CBR (similar to NC 10C), low level of resistance to early leafspot (similar to NC 6), low level of tolerance to tomato spotted wilt virus, and highly susceptible to sclerotinia blight. No known insect resistance. Pod and seed characteristics similar to NC 7. 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. Has field tolerance to tomato spotted wilt virus, low level of resistance to CBR, susceptible to early leafspot and sclerotinia blight. No known insect resistance. Bright shapely pods make NC-V 11 one of the three varieties preferred by VC area shellers (VA 93B first, NC 10C second, NC-V11 third). 19. Southern Runner Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 1986 and protected under the Plant Variety Protection Act. Matures 15 to 20 days later than Florunner with smaller seed and pod size. Has normal oleic/linoleic fatty acid ratio with runner growth habit. Has resistance to late leafspot, white mold, rust, and tomato spotted wilt virus. Possibly has some resistance to Southern corn rootworm, possibly more drought tolerant and usually lower LSK and less alfatoxin than Florunner. Tan seedcoat and prominent exterior hull venation. 20. SunOleic 97R Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 1997 and protected under the 1994 Amendment of the Plant Variety Protection Act. Same maturity group as Florunner, with about the same seed and pod size. High oleic/linoleic fatty acid ratio with typical runner growth habit. No known disease or insect resistance. Generally very similar to Sunrunner, but with high oleic oil chemistry. 21. Tamrun 98 Developed by Drs. Charles Simpson and the late O. D. Smith, Texas A & M University. Released in 1998 with plant variety protection applied for under the 1994 Amendment of the Plant Variety Protection Act. Similar to Florunner in maturity, seed and pod size, normal oleic/linoleic acid ratio, and runner growth habit. Primary reason for release was resistance to sclerotinia blight. 22. VA 93B Developed by Virginia Agricultural Experiment Station and USDA-ARS. Released in 1993 and protected under the Plant Variety Protection Act. Maturity range is earlier than NC 7 by about seven days in the VC area. Has smaller seed and pod size than NC 7, normal oleic/linoleic fatty acid ratio, and bunch growth habit. No known insect resis- tance and has a moderate resistance to sclerotinia blight. Bright, shapely, fancy pods made VA 93B the most preferred variety for in-shell products in the VC shelling industry. 13 23. VA 98R Developed by Virginia Agricultural Experiment Station and USDA-ARS. Released in 1998 with plant variety protection applied for under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is early, similar to NC 7 with smaller seed and pod size, normal oleic/linoleic fatty acid ratio, and runner growth habit. No known insect or disease resistance. However, early data indicate that it might be less susceptible to sclerotinia blight than some Virginia type varieties (NC 7, NC 10C, Gregory, and NC 12C). Other characteristics are high yield potential with excellent pod characteristics for in-shell processing (bright pod color and typical peanut shape). Its runner growth habit and prominent erect mainstem makes for easier digging with rows being easily determined. 24. VA-C 92R Developed by Virginia Agricultural Experiment Station, North Carolina Agricultural Research Service, and USDA- ARS. Released in 1992 and protected under the Plant Variety Protection Act. Maturity range same as NC 7 with smaller seed and pod size and normal oleic/linoleic fatty acid ratio. Has intermediate growth habit with moderate field tolerance to tomato spotted wilt virus, susceptible to early leafspot. Has uniform pink seed. Its high yield potential made it very popular in the VC area until area shellers voiced concerns over its relatively dark hulls. 25. ViruGard Developed by Dr. Ernest Harvey, AgraTech Seeds Inc. Released in 1997 under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is earlier than Florunner with larger seed and pod size, mid-level oleic/ linoleic fatty acid ratio, and intermediate growth habit. Generally smaller leaflet size than Florunner. No known insect resistance. Resistant to tomato spotted wilt virus. Seedcoat color lighter than Florunner. 14 ALABAMA AGRICULTURAL EXPERIMENT STATION Sources of Seed Dr. W. D.
