The 2007 Alabama Performance Comparison of Peanut Varieties
JAMES P. BOSTICK, LARRY W. WELLS, and BRIAN 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 and Discussion The 2007 tests were conducted at the Wiregrass Research and Extension Center in Headland, AL. During 2007, 24 entries were evaluated under irrigation and dryland. The experimental design for each test was a randomized complete block consisting of tworow plots, 20 feet long, replicated four times. The dryland tests were planted on May 8, and irrigated tests were planted on May 9. All tests were planted 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 in all tests. The irrigated test entry considered to be earlier than Florunner in maturity was dug on September 19. This entry was Andru II. Entries with maturity near the same as Florunner were dug on October 1. These entries were AP-4, AT 3081R, AT 3085RO, C 724-19-25, Carver, Exp 27-1516, Exp 31-1516, Florida Fancy, Georgia-03L, Georgia-06G, Georgia Green, Georgia Greener, and McCloud. Entries moderately later than Florunner, AP-3, C-99 R, Tifguard, CRSP 14, CRSP 910, Florida 07, Georgia-02C, and York, were dug on October 11. Entries CRSP 648 and CRSP 702 are considered later than Florunner, and were dug on October 18. The dryland test entry considered to be earlier than Florunner was dug on September 24. This entry was Andru II. Entries with maturity near the same as Florunner were dug on October 9. These entries were AP-4, AT 3081R, AT 3085RO, C 724-19-25, Carver, EXP 27-1516, Exp 31-1516, Florida Fancy, Georgia-03L, Georgia-06G, Georgia Green, Georgia Greener, and McCloud. Entries moderately later than Florunner, AP-3, C-99 R, Tifguard, CRSP 14, CRSP 910, Georgia-02C, Florida 07, and York were dug on October 15. Entries CRSP 648 and CRSP 702 are considered later than Florunner, and were dug on October 22. The information presented here represents data from three years at one location. Yield and disease occurrence data have been subjected to an analysis of variance. This statistical evaluation determined the overall averages for all varieties, coefficient of variation (CV) and the least significant differences (LSD). The LSD values represent the difference required 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 8-12 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. Terms Used SMKRS count/lb. (number per pound of sound mature kernels riding screen)—Number of sound whole mature kernels from 1 pound of the shelled sample riding a 15/64 x 1-inch slotted screen or a 16/64 x 3/4-inch slotted screen for Virginia or Runner varieties, respectively. 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.

Hagan, Professor of Plant Pathology, for providing the disease evaluation data and to Glenn Wehtje, Professor of Agronomy and Soils, for the statistical analysis.

Pounds of peanut seed at various seed count per pound required to plant 1 acre at five, six or seven seed per foot of row with single row width spacing. (For twin-rows at 36-inch centers, divide seed per foot for single row by two to determine seed per foot for each twin-row.) To determine pounds per acre at 36-inch row spacing, use the following formula: (A) Seed per foot x linear feet in 1 acre = pounds per acre Seed count per pound (B) To determine linear feet in one acre at 36-inch row spacing: 43,560 square feet per acre = 14,520 linear feet in 1 acre 3 square feet (C) Example: 6 seed per foot x 14,520 linear feet = 109 pounds per acre 800 seed per pound

Andru II has early maturity (130+ days) in Florida studies, but not quite as early as Andru 93 or ViruGard. It has excellent tomato spotted wilt virus resistance (equal to or better than Georgia Green), with excellent pod yields, good grades, and high oleic oil chemistry (80+% oleic fatty acid). Andru II has some white mold resistance equal to or better than Georgia Green. Its growth habit is intermediate to semirunner with seed size similar to Georgia Green. Its pod yields have been equal to Georgia Green. Andru II should be an excellent choice for southeastern U.S. production, being the most productive early maturity high oleic cultivar currently available.
