The 199 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. 0 P~DUCTION The 198 test was conducted at the Wiregrass 0 in Headland, Alabama. The experimental design was a randomize complete block consisting of two-row plots, 20 feet long, replicated four times. The test was planted on May , 199 , with a cone planter at a rate of six seed per foot of row. Recommended agronomic practices were PL follov~d regarding fertility, disease, insect, and weed control. The test was conducted under irrigation. Entries consideredtob rli tne a dug on September .1r-k499. These entries \ 6W include All other entries except Southern Runner and F/V) Florida hJl 8 were dug on 49.Southern Runner and Florida MDR 98, considered to be later in maturity, were dug on .. Information concerning relative 1 tii y was provided by the plant breeder responsible for developing the variety. j )'i DISCUSSION N't\Peformance comparisons among varieties should be drawn judiciously under these circumstances. Yield and disease occurrence data have been subjected to an analysis/variance. This statistical evaluation determined the overall averages for all varieties, coefficient of variation (C a d the least significant differences (LSD). The LSD values represent the difference required for the averages otjarieties 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 Substation. 2 ALABAMA AGRICULTURAL EXPERIMENT STATION Terms Used g/100 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. (Note: one ounce equals 28.4 grams) 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. ACKNOWLEDGMENTS 4J/ The authors express appreciation to Austin K. Hagan, Professor of lant Pathology, for providing the disease evaluation data and to Glenn Wehtje, Professor of Agronomy and Soils,1for the statistical analysis. Appreciation is also expressed to Sara Casey and Larry Savelle, WiregrassS.mtatiR, for their cooperation. 1998 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES3 TABLE 1.

Released in 1984 and protected under the Plant Variety Protection Act. Has slightly larger seed and pod size than Florunner and the same maturity range. Normal oleic/ linoleic fatty acid range with some tomato spotted wilt virus tolerance. No other known disease tolerance and no known insect resistance. Typical runner growth habit with an erect mainstem. 13. GK 7 High Oleic Developed by Dr. Kim Moore, AgraTech Seeds Inc. Released in 1997 and protected under the 1994 Amendment of the Plant Variety Protection Act. Maturity range similar to Florunner with seed and pod size slightly larger. High oleic/linoleic fatty acid ratio and some tolerance to tomato spotted wilt virus. No other known disease or insect resistance. Typical runner growth habit with erect mainstem. 14. 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. It is preferred for the in-shell export market due to its large pod and seed size. 15. NC-12C Developed by North Carolina Agricultural Research Service. Released in 1996 and protected under the 1994 Amendment 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.

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 make VA 93B the most preferred variety for in-shell products in the VC shelling industry. 21. 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.
