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 The 2002 tests were conducted at the Wiregrass Research and Extension Center in Headland, Alabama. Prior to 2000, comparisons were made only under irrigation. During 2002, 22 entries were evaluated under irrigation, 16 entries were evaluated dryland, and 10 entries were evaluated late-planted dryland. The experimental design for each test was a randomized complete block consisting of two-row plots, 20 feet long, replicated four times. The irrigated test was planted on May 6, the dryland test was planted on May 17, and the lateplanted dryland test was planted on June 10. 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 entries considered to be earlier than Florunner in maturity were dug on September 13. These entries included Andru II, GP-1, VA-C 92R, and ViruGard. All other entries were dug on September 20, except for those that are considered later than Florunner—C34-24, C-99R, DP-1, Georgia-01R, Hull, and Southern Runner—which were dug on October 3. The dryland test entries considered to be earlier than Florunner were dug on September 20. These entries were Andru II, GP-1, and ViruGard. All other entries were dug on September 30, except for those entries that are considered later than Florunner—C34-24, C-99R, DP-1, Georgia-01R, Hull, and Southern Runner—which were dug on October 9. In the late-planted dryland test, Andru II and ViruGard were dug on October 23, and all other entries were dug on November 5. Information concerning relative maturity for all test entries was provided by the plant breeder responsible for developing the variety. DISCUSSION 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. Bostick is an adjunct professor of the Auburn University Department of Agronomy and Soils and executive secretary of the Alabama Crop Improvement Association; Wells is superintendent and Gamble is associate superintendent of the Wiregrass Research and Extension Center. 1 6 ALABAMA AGRICULTURAL EXPERIMENT STATION The CV, which is expressed as a percentage, is a relative measure of variation within a set of data. CV values of 8 to 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 3/4inch slotted screen and riding a 16/64 x 3/4-inch slotted screen. ACKNOWLEDGMENTS The authors express appreciation to Austin K. Hagan, professor of Entomology and Plant Pathology, for providing the disease evaluation data and to Glenn Wehtje, professor of Agronomy and Soils, for the statistical analysis. Appreciation is also expressed to Amy Folger and Larry Savelle, Wiregrass Research and Extension Center, for their cooperation. 2002 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES 7 AT THE TABLE 1.

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 2002 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES 19 AT THE TESTS DURATION DAILY R AINFALL D ATA R ECORDED WIREGRASS R ESEARCH AND E XTENSION CENTER , HEADLAND, ALABAMA, 2002 MAY in DATE APR in JUNE in JULY in AUG in SEPT in OCT in NOV in 1 — 0.05 — 0.30 — 0.09 — 2 — — — — 0.66 — — 3 — — — — 0.11 — — 4 — — 0.02 — — — — 5 — — 0.57 0.02 — — 0.38 6 — — — — — — — 7 — — 0.04 0.11 — 0.10 0.05 8 — — 0.06 — — — — 9 1.40 — 0.40 0.05 — — — 10 0.88 — — — — — — 11 — — — — — — — 12 0.22 0.73 — — — — — 13 0.12 — — 1.29 — 0.05 — 14 — 0.89 — — — 0.33 0.14 15 0.19 — 0.74 — 1.26 0.69 0.48 16 — — — — — — 0.71 17 — 0.25 0.49 — — — — 18 — 0.18 0.05 — — — — 19 — — — — — — — 20 — — — — 0.09 0.04 — 21 — — — 0.07 — — 0.70 22 — — 0.06 — 0.05 — — 23 — — 0.38 0.65 — — — 24 — — 0.02 0.14 — — 0.41 25 — — — 1.02 — 0.86 0.10 26 — — 0.05 0.10 — 0.15 0.05 27 — — 0.03 — 0.25 0.60 0.61 28 — — 0.03 0.24 0.07 — 0.10 29 — 0.51 0.97 0.29 — — 0.27 30 — — 0.03 0.08 0.02 — 0.26 31 — 0.25 — — 0.60 — — TOTALS1 3.35 2.86 3.94 4.15 3.11 2.91 4.26 1 Total daily rainfall from April through November, 2002 = 30.00 in; 2001 = 31.19 in; 2000 = 19.81 in. — — 0.03 0.16 0.12 0.40 — — — 0.43 0.10 3.20 0.05 — — 0.86 0.08 — — 0.02 — — — — — — — — — — — 5.45 20 ALABAMA AGRICULTURAL EXPERIMENT STATION AT THE T ESTS DURATION DAILY MAXIMUM TEMPERATURES RECORDED WIREGRASS RESEARCH AND EXTENSION CENTER, HEADLAND, A LABAMA, 2002 MAY o DATE APR o JUNE o JULY o AUG o SEPT o OCT o NOV o F F F F F F F F 1 82 2 75 3 83 4 86 5 74 6 73 7 70 8 79 9 79 10 68 11 74 12 76 13 77 14 80 15 83 16 83 17 85 18 89 19 90 20 91 21 90 22 89 23 86 24 82 25 88 26 88 27 72 28 88 29 90 30 88 31 1 Data not collected. 90 90 91 91 94 86 82 94 93 94 94 95 92 89 77 83 87 87 75 71 74 74 76 82 87 89 92 92 92 80 90 90 93 95 97 97 90 89 92 78 87 89 91 95 97 98 86 88 82 87 87 90 77 81 85 87 86 82 91 91 87 90 91 93 92 90 92 97 94 93 93 93 95 94 87 93 92 95 96 99 100 98 95 90 90 89 89 87 90 90 90 90 90 91 91 90 90 91 95 90 90 89 92 92 93 93 85 90 92 93 92 95 92 93 94 96 98 95 93 90 90 90 86 86 82 86 91 95 96 94 90 92 91 97 99 95 80 78 88 91 93 93 91 90 92 90 91 79 77 85 78 82 86 85 86 89 88 85 89 —1 — — — — — — — — — 72 71 73 79 82 79 80 70 75 — — — — 82 82 78 69 66 64 64 79 72 66 70 71 82 77 64 62 64 72 60 52 63 67 69 70 56 58 65 63 69 59 54 59 2002 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES 21 AT THE T ESTS DURATION DAILY M INIMUM TEMPERATURES RECORDED WIREGRASS R ESEARCH AND E XTENSION CENTER , HEADLAND, ALABAMA, 2002 MAY o DATE 1 APR o JUNE o JULY F 66 o AUG F 71 o SEPT F 69 o OCT F 67 o NOV F 41 o F 56 F 69 F 67 2 50 3 57 4 49 5 43 6 41 7 43 8 56 9 60 10 60 11 61 12 62 13 62 14 61 15 63 16 68 17 63 18 64 19 64 20 66 21 65 22 68 23 57 24 57 25 61 26 57 27 55 28 56 29 70 30 66 31 1 Data not collected 71 71 72 68 65 65 71 68 68 68 67 66 49 52 58 64 69 51 46 48 48 47 55 63 64 65 65 68 66 63 69 71 72 68 70 69 71 65 65 68 68 70 70 65 60 63 65 67 67 67 67 67 69 70 71 67 69 68 70 68 70 70 67 68 68 70 69 66 71 69 70 71 70 69 70 73 73 74 69 67 69 70 68 70 70 70 68 70 68 67 67 67 67 68 72 66 60 60 63 65 68 70 68 68 69 69 72 67 67 68 69 71 72 69 68 67 67 68 69 68 68 67 67 71 70 67 66 67 68 67 70 67 67 68 68 70 68 69 69 67 68 69 68 67 60 65 66 66 68 67 66 68 69 67 64 64 64 68 —1 — 68 66 62 44 45 45 45 60 70 70 67 69 60 62 62 65 73 47 41 42 56 55 50 37 40 47 52 66 56 38 36 45 51 39 33 37 49 50 43 29 32 38 35 38 27 27 41 22 ALABAMA AGRICULTURAL EXPERIMENT STATION DESCRIPTIONS OF 2002 PEANUT VARIETY TEST ENTRIES 1. AgraTech 201 Developed by Dr. Kim Moore, AgraTech Seeds Inc. Released in 1999 with variety protection to be applied for under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is same as Florunner with similar seed and pod size. The oleic/linoleic fatty acid ratio is high with typical runner growth habit with erect mainstem. Carries tolerance to tomato spotted wilt virus with thin hulls and dark green foliage. 2. Andru II Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. Also carries a patent on the high oleic trait prohibiting nonlicensed parties from saving seed for replanting. 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 semi-runner with seed size similar to Georgia Green. Its pod yields have been equal to Georgia Green. Andru II should be an excellent choice for SE production, being the most productive early maturity high oleic cultivar currently available. Anderson’s Peanut Company has the marketing contract on this variety. 3. C 34-24 An advanced breeding line developed by Dr. Corley Holbrook, USDA-ARS, Tifton, Georgia. Late maturity range with slightly larger seed and pod size than Florunner. Has runner growth habit with prominent main stem. Resistance to tomato spotted wilt virus, and early and late leaf spot. 4. C-99R Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 1999 with variety protection applied for under the 1994 Amendment of the Plant Variety Protection Act. The maturity range is 10 to 14 days later than Florunner with large seed and pod size and normal oleic/linoleic fatty acid ratio. Runner growth habit with resistance to late leafspot, white mold, and tomato spotted wilt virus. Other characteristics include good yields and grades with multiple disease resistance (as noted); similar to Florida MDR 98 but more normal oleic fatty acid content (55 to 59%) with somewhat darker green foliage. 5. C156-47 An unreleased advanced breeding line developed by Dr. Corley Holbrook, ARS-USDA, Tifton, Georgia. Same maturity range as Florunner with similar seed and pod size as Florunner. Has runner growth habit with fairly prominent mainstem. Good yield and grade potenial with resistance to tomato spotted wilt virus. 6. Carver Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. Carver has medium maturity (135 to 140 days), runner growth habit (prominent center stem), runner pod and seed size, with tomato spotted wilt virus and white mold resistance somewhat better than Georgia Green, and resistance to cylindrocladium black rot and Rhizoctonia limb rot. Carver has excellent yield potential with somewhat larger and elongated seed with normal oil chemistry. 7. DP-1 Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. DP-1 is a late maturity (150+days) cultivar with excellent disease resistance. DP-1 has the highest level of resistance to late leaf spot, tomato spotted wilt virus, and white mold currently available in a U.S. peanut cultivar. Yields of 4800 pounds per acre have been recorded in Florida tests with no fungicide applied for leaf spot control. DP-1 has normal oil chemistry and seed size similar to GK 7 and Florunner. It has somewhat less vine growth than C-99R. Seed will be marketed through Damascus Peanut Company. 8. Florunner Developed by Dr. Al Norden, University of Florida Agricultural Experiment Station. Released in 1969. Matures in approximately 135 days and has normal oleic/linoleic fatty acid ratio. Until the occurrence of tomato spotted wilt virus, 2002 ALABAMA PERFORMANCE COMPARISON OF PEANUT VARIETIES 23 Florunner had been the industry standard of comparison with respect to yield for runner varieties. It is still the standard of comparison for many milling characteristics for runner varieties. No known disease or insect resistance. 9. Georgia-01R Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released under the 1994 amendment of the Plant Variety Protection Act. Late maturity range with mid-oleic oleic/linoleic fatty acid ratio with seed and pod size similar to C-99R. Is resistant to tomato spotted wilt virus and carries tolerance to leaf spot and white mold. Observations have indicated less occurrence of cylindrocladium black rot and leaf hopper damage than more susceptible varieties. 10. Georgia -02C Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Same maturity range as Florunner with seed and pod size slightly larger than Florunner. High oleic/linoleic fatty acid ratio with runner growth habit and vine growth more consistent with Florunner than Georgia Green. Resistant to tomato spotted wilt virus and cylindrocladium black rot. 11. Georgia Green Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released in 1995 and protected under the 1994 Amendment of the Plant Variety Protection Act. Same maturity range as Florunner with seed and pod size similar to or slightly more round than Florunner. Normal oleic/linoleic fatty acid ratio with intermediate growth habit and considerably less vine growth than Florunner. Resistant to tomato spotted wilt virus, but carries no known insect resistance. Georgia Green has proven to have yield stability across a wide range of different environments under both irrigated and non-irrigated conditions and in both single and twin row patterns. 12. Georgia Hi-O/L Developed by Dr. Bill Branch, University of Georgia Agricultural Experiment Station. Released in 1999 with plant variety protection applied for under the 1994 Amendment of the Plant Variety Protection Act. Same maturity range as Florunner with larger seed and pod size, high oleic/linoleic acid ratio, and intermediate growth habit. Resistant to tomato spotted wilt virus. 13. Gregory Developed by Dr. Tom Isleib, North Carolina Agricultural Research Service. Released in 1997 with plant variety protection applied for under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is earlier than NC 7 with larger seed and pod size. Has normal oleic/linoleic fatty acid ratio and intermediate growth habit. The only known resistances of Gregory are to cylindrocladium black rot (this is very slight: i.e., it is less susceptible than NC 7) and to tomato spotted wilt virus (6.5% infection rate compared with 9.2% for NC-V11). Like NC 7 and NC 12C, Gregory is extremely susceptible to sclerotinia blight. Gregory has a pink seed coat. 14. GP-1 Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. Also carries a patent on the high oleic trait prohibiting nonlicensed parties from saving seed for replanting. GP-1 has early maturity (125-130 days) in Florida tests, with high oleic oil chemistry, runner seed size, and intermediate runner growth habit. GP-1 has some tomato spotted wilt virus resistance, but not quite as good as Georgia Green, being most suitable for lower tomato spotted wilt virus pressure situations. Pod yields have been equal to Georgia Green in low tomato spotted wilt virus pressure situations, but less where tomato spotted wilt virus was high. Seed size is somewhat larger than Georgia Green. FFSP has a marketing contract with Golden on this variety. 15. Hull Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. Also carries a patent on the high oleic trait prohibiting nonlicensed parties from saving seed for replanting. Hull is a later maturity (150+days) jumbo runner seed size, high oleic cultivar with excellent pod yields and multiple disease resistance. Hull has resistance to tomato spotted wilt virus and late leaf spot similar to C-99R (better than Georgia Green). It has white mold resistance equal to or better than C-99R (better than Georgia Green). Hull also has some good resistance to cylindrocladium black rot and some root knot nematode resistance. Its seed size is similar to C-99R, with somewhat less vine growth. 24 ALABAMA AGRICULTURAL EXPERIMENT STATION 16. NC-V11 Developed by North Carolina Agricultural Research Service, Virginia Agricultural Experiment Station, and USDAARS. Released in 1998 and protected under the Plant Variety Protection Act. Maturity range same as NC 7 with smaller seed and pod size, normal oleic/linoleic fatty acid ratio, and runner growth habit. Has field tolerance to tomato spotted wilt virus, low level of resistance to cylindrocladium black rot, and is susceptible to early leafspot and sclerotinia blight. No known insect resistance. Bright shapely pods make NC-V11 one of the three varieties preferred by VC area shellers (VA 93B first, NC 10C second, NC-V11 third). 17. Norden Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 2002 under the 1994 Amendment of the Plant Variety Protection Act. Also carries a patent on the high oleic trait prohibiting nonlicensed parties from saving seed for replanting. Norden is a medium maturity (135-140 days) variety, with runner growth habit (prominent center stem), runner size pods and seed, very good tomato spotted wilt virus resistance, and high oleic oil chemistry. It is a replacement for SunOleic 97R in FFSP program. Norden has shown pod yields and tomato spotted wilt virus resistance equal to or better than Georgia Green in Florida tests and a somewhat larger seed size. Norden has been equal to Georgia Green in resistance to white mold, leaf spot, and rhizoctonia disease. 18. Southern Runner Developed by Dr. Dan Gorbet, University of Florida Agricultural Experiment Station. Released in 1986 and protected under the Plant Variety Protection Act. Matures 15 to 20 days later than Florunner with smaller seed and pod size. Has normal oleic/linoleic fatty acid ratio with runner growth habit. Has resistance to late leafspot, white mold, rust, and tomato spotted wilt virus. Possibly has some resistance to Southern corn rootworm. Possibly has more drought tolerance and usually has lower LSK and less alfatoxin than Florunner. Tan seedcoat and prominent exterior hull venation. 19. VA 98R Developed by Virginia Agricultural Experiment Station and USDA-ARS. Released in 1998 with plant variety protection applied for under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is early, similar to NC 7 with smaller seed and pod size, normal oleic/linoleic fatty acid ratio, and runner growth habit. No known insect or disease resistance. However, early data indicate that it might be less susceptible to sclerotinia blight than some Virginia type varieties (NC 7, NC 10C, Gregory, and NC 12C). Other characteristics are high yield potential with excellent pod characteristics for in-shell processing (bright pod color and typical peanut shape). Its runner growth habit and prominent erect mainstem make for easier digging with rows being easily determined. 20. VA-C 92R Developed by Virginia Agricultural Experiment Station, North Carolina Agricultural Research Service, and USDAARS. Released in 1992 and protected under the Plant Variety Protection Act. Maturity range same as NC 7 with smaller seed and pod size and normal oleic/linoleic fatty acid ratio. Has moderate field tolerance to tomato spotted wilt virus and is susceptible to early leafspot. Has intermediate growth habit and uniform pink seed. Its high yield potential made it very popular in the VC area until area shellers voiced concerns over its relatively dark hulls. 21. ViruGard Developed by Dr. Ernest Harvey, AgraTech Seeds Inc. Released in 1997 under the 1994 Amendment of the Plant Variety Protection Act. Maturity range is earlier than Florunner with larger seed and pod size, mid-level oleic/linoleic fatty acid ratio, and intermediate growth habit. Generally smaller leaflet size than Florunner.
