Department of Agronomy and Soils Departmental Series No. 193 Alabama Agricultural Experiment Station Auburn University Lowell T. Frobish, Director February 1996 be 1995 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES P. Bostick, H W. Ivey 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 1995 test was conducted at the Wiregrass Substation, Headland, Alabama. The experimental design was a randomized complete block consisting of two row plots, 20 feet long, replicated four times. The test was planted on April 27, 1995 with a cone planter at a rate of six seed/per foot. Reconmmended agronomic practices were followed regarding fertility, disease, ins ect, and weed control. The test was conducted under irrigation. Entries considered to be earlier than Florunner in maturity were dug on September 1, 1995. These entries included AT 120, Andru 93, Marc 1, NC 7, NC Vii1, and Southwest Runner. All other entries except Southern Runner and Georgia Browne were dug on September 8, 1995. Southern Runner and Georgia Browne, considered to be later in maturity, were dug on September 26, 1995. Information concerning relative maturity was provided by the plant breeder -1- 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 derivation of grade factors followed Federal-State Inspection Service procedures for grading farmer-stock peanuts. Terms Used: g/100 SMKRS (Grams 2 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 one - inch slotted screen or a 16/64 x one - inch slotted screen for Virginia or Runner varieties respectively. Pct. SMKRS (sound mature kernels riding screen)-Portion of shelled sample as described above. 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 kernels)-Kernels that pass through a 15/64 x one - inch slotted screen or 16/64 x one - inch slotted screen for Virginia or Runner varieties respectively. Pct. 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 kernels)-All shelled sample kernels including TSMK, OK, DK. z'One ounce equals 29 grams. -2- 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. Information contained herein is available to all persons regardless of race, color, sex or national origin. -3- TABLE 1.
