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 2006 tests to compare performance of peanut varieties were conducted at the Wiregrass Research and Extension Center in Headland, AL. Prior to 2000, comparisons were made only under irrigation. During 2006, 23 entries were evaluated under irrigation, and 21 entries were evaluated dryland. The experimental design for each test was a randomized complete block consisting of tworow plots, 20 feet long, replicated four times. The irrigated tests were planted on May 18, and dryland tests were planted on May 17. 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 22. This entry was Andru II. Entries with maturity near the same as Florunner were dug on October 3. These entries were ANorden, AT 3081R, C 724-19-25, Carver, AT 3085A, Exp 27-1516, Georgia-03L, Georgia Green, McCloud, Gregory, and NC-V11. Entries moderately later than Florunner, AP-3, C-99 R, C 724-19-15, Georgia-02C, Georgia05E, Tifrunner, and Florida 07, were dug on October 12. Entries CRSP 38, C 12-3-114-58, Georgia-01R, and York are considered later than Florunner and were dug on October 26. The dryland test entry considered to be earlier than Florunner was dug on October 3. This entry was Andru II. Entries with maturity near the same as Florunner were dug on October 12. These entries were ANorden, AT 3081R, C 724-19-25, Carver, AT 3085A, EXP 271516, Georgia-03L, Georgia Green, and McCloud. Entries moderately later than Florunner, AP-3, C-99 R, C 724-19-15, Georgia-02C, Georgia 05E, Tifrunner, and Florida 07 were dug on October25. Entries CRSP 38, C 12-3-114-58, Georgia-01R, and York are considered later than Florunner, and were dug on November 6. 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 Bostick is an adjunct professor of the Auburn University Department of Agronomy and Soils and executive Vice President of Alabama Crop Improvement Association; Wells is superintendent and Gamble is associate superintendent of the Wiregrass Research and Extension Center. 1 3 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.

(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 1 16 Tests Duration Daily Rainfall Data Recorded at the Wiregrass Research and Extension Center, Headland, Alabama 2006 DATE APR in MAY in JUNE in JULY in AUG in SEPT In OCT in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 1 0.11 0.10 0.16 0.66 0.05 0.30 0.25 1.12 0.17 1.20 0.25 1.37 1.13 0.02 0.12 0.18 1.24 0.02 0.04 1.16 0.02 2.25 0.05 0.07 1.73 0.23 0.23 1.05 0.43 0.31 0.12 0.33 0.10 0.28 0.02 0.19 0.55 0.23 0.02 0.05 0.19 0.43 0.01 0.61 1.57 0.06 0.06 0.11 0.01 0.38 0.33 0.22 0.01 0.67 0.02 TOTALS 1.88 4.08 2.64 2.61 3.48 4.58 3.26 1 Total daily rainfall from April through October, 2006 = 28.14 in; 2005 = 40.65 in; 2004 = 34.34 in . 17 Tests Duration Daily Maximum Temperatures Recorded at the Wiregrass Research and Extension Center, Headland, Alabama 2006 DATE APR °F MAY °F JUNE °F JULY °F AUG °F SEPT °F OCT °F 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 84 84 88 87 76 78 85 85 86 73 75 79 79 82 88 88 86 88 93 89 92 89 83 85 87 87 77 75 80 78 74 76 83 87 88 85 85 78 84 80 82 82 82 79 82 82 82 77 85 88 92 91 91 91 93 94 92 93 96 92 94 94 94 94 87 1 ---89 89 93 94 94 98 97 87 87 93 94 98 92 90 93 99 101 101 96 94 ---93 93 94 94 97 96 95 95 98 98 98 87 89 90 93 95 96 96 98 100 98 98 98 94 98 98 94 93 88 94 94 98 98 93 88 95 95 96 94 87 92 94 95 94 94 94 93 95 86 90 ---93 93 93 93 96 95 93 92 90 86 93 93 96 96 96 92 86 91 93 92 92 86 77 83 85 81 84 86 87 88 88 89 90 90 84 80 83 87 92 91 81 80 82 88 75 79 88 88 88 86 88 87 78 76 75 83 85 81 69 74 76 72 75 85 88 70 77 72 61 68 59 62 72 64 73 ---- 1 Data not collected 18 Tests Duration Daily Minimum Temperatures Recorded at the Wiregrass Research and Extension Center, Headland, Alabama 2006 DATE APR °F MAY °F JUNE °F JULY °F AUG °F SEPT °F OCT °F 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 60 61 64 50 41 46 51 56 42 48 48 51 53 54 59 60 66 64 64 65 65 63 58 61 63 64 56 50 51 58 54 56 58 63 67 60 73 68 65 63 64 53 53 57 63 51 51 58 51 52 66 64 64 64 64 64 72 71 69 69 69 69 69 68 63 1 ---66 60 60 60 60 67 70 70 67 67 67 66 66 65 66 66 75 72 71 71 ---70 70 70 67 68 74 72 74 75 73 72 68 68 71 70 70 70 70 70 74 74 73 73 71 71 71 72 71 72 71 73 71 70 72 70 70 71 71 74 74 78 74 76 71 71 71 71 74 7 73 ---73 74 72 71 74 72 73 72 72 71 72 72 73 76 73 72 71 71 69 69 71 71 67 67 67 70 69 69 68 65 65 65 72 72 59 56 56 65 72 67 57 55 55 54 51 57 58 58 51 60 55 57 52 54 55 58 58 54 45 48 58 58 70 64 65 48 48 42 41 41 47 53 53 45 46 ---- 1 Data not collected 19 DESCRIPTIONS OF 2006 PEANUT VARIETY TEST ENTRIES 1.
