February 191F Agronomy and Soils Departmental Series No. 201 Alabama Agricultural Experiment Station James E. Marion, Director Auburn University, Alabama 1996 ALABAMA PERFORMANCE COMPARISON -OF PEANUT VARIETIES J.P. BOSTICK, L.W. WELLS, AND B.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 1996 test was conducted at the Wiregrass Substation, Headland, Alabama. The experimental design was a randomized complete block consisting of 2 row plots, 20 feet long, replicated 4 times. The test was planted on May 7, 1996 with a cone planter at a rate of six seed/ft. 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 20, 1996. These entries included AT. 120, Andru 93, NC 7 and NC Vl11. All other entries except Southern Runner were dug on September 26, 1996. Southern Runner, considered to be later in maturity, was dug on October 14, 1996. 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 between varieties should be drawn judiciously under these circumstances. Tomato spotted wilt virus occurrence and yield data have been subjected to an analysis of variance and means separated by using Duncan's Multiple Range Test. Means followed by the same letter (A-I) are not significantly different at the 0.05 level of probability. Data is not presented for white mold or limb diseases since visual evaluation revealed none or only slight occurrence. 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: 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 slotted screen or a 16/64 x 1 inch slotted screen for Virginia or Runner varieties respectively. Pct. SMKRS (sound mature kernels riding screen)-Portion of shelled sample as described above. 2 One ounce equals 28.4 grams. Pet. 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 kemels)-Kemels that pass through a 15/64 x 1 inch slotted screen or 16/64 x 1 inch slotted screen for Virginia or Runner varieties respectively. Pet. DK (damaged kernels)-Kemels which are moldy, decayed, affected by insects or weather conditions resulting in seed coat or cotyledon discoloration or deterioration. Pct. TK (total kemels)-All shelled sample kernels including TSMK, OK, DK. ACKNOWLEDGEMENTS The authors express appreciation to A.K. Hagan, Associate Professor of Plant Pathology for providing the disease evaluation data and to Glenn Wehtje, Associate Professor of Agronomy and Soils for the statistical analysis. Appreciation is also expressed to Sara Casey, Wiregrass Substation for her cooperation. Table 1.
