1994 ALABAMA PERFORMANCE COMPARISON PEANUT VARIETIES
J.P. Bostick, H.W. Ivey, and B.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 In 1994 the test was conducted at the Wiregrass Substation at Headland, Alabama. The experimental design for the test was a randomized complete block consisting of two row plots, 20 feet long replicated four times. The test was planted on May 5, 1994 with a cone planter at a rate of six seed/ft. Recommended agronomic procedures were followed regarding fertility, disease, and insect control. The test was conducted under irrigation. Entries considered to be earlier than Florunner in maturity were dug on September 7, 1994. These entries included Marc 1, AgraTech 127, and Andru 93. All other entries except Southern Runner and Georgia Browne were dug on September 13, 1994. Southern Runner and Georgia Browne, considered to be later in maturity, were dug on September 29, 1994. Information concerning relative maturity was provided by the plant breeder responsible for developing the variety.

Adjunct Professor of Agronomy and Soils and Executive Secretary of Alabama Crop Improvement Association; Superintendent and Assistant Superintendent, Wiregrass Substation, respectively.

DISCUSSION The information presented here represents data for three years, but only one 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-F) are not significantly different from each other 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 replication 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 (Gramsper 100 sound mature kernels ridingscreen)-Weight in grams of 100 sound whole mature kernelsfrom the shelled sample ridinga 15/64 x one- inch slotted screen or a 16/64 x one-inch slotted screenfor Virginia or Runner varietiesrespectively. Pct SMKRS (sound mature kernels riding screen)-Portion of shelled sample as describedabove. Pc SS (soundsplits)-Portionof shelled sample split or broken but not damaged. Pet TSMK (total sound mature kernels)-Portionof the shelled sample comprised of sound mature kernels plus sound splits. Pct OK (other kernels)-Kernels thatpass through a 15/64 x one-inch slotted screen or 16/64 x one-inch slotted screenfor Virginia or Runner varietiesrespectively.

Pt. DK (damagedkernels)-Kernels which are moldy, decayed, affected by insects or weather conditions resulting in seed coat or cotyledon discolorationor deterioration. Pc. TK (total kernels)-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.
