DescriptionComparable or better resistance to early and late leafspots (Cercospora arachidicola and Cercosporidium personatum, respectively) and tomato spotted wilt virus (TSWV) as Southern Runner and Florida MDR 98. Produces significantly higher yields and dollar values without pesticides as compared to these other multiple resistant cultivars and when grown with recommended pesticides, found to be comparable to Georgia Green in TSWV resistance, pod yield, total sound mature kernel grade, and dollar value return per hectare. Preliminary field trials also shows moderate resistance to white mold and stem rot (Sclerotium rolfsii), Cylindrocladium black rot (Cylindrocladium parasiticum), leafhoppers (Empoasca fabae) and/or leaf scorch (Leptosphaerulina crassiasca). Spreading runner growth habit, tan testa color, and late maturity similar to Southern Runner, Florida MDR 98, and C-99R. Maturity approx. 2 to 3 weeks later compared to Georgia Green in south Georgia. Foliage dark green, prominent mainstem, and alternate branching pattern. Significantly greater pod bulk density (346 vs 316 kg m-3), more pronounced pod reticulation and constriction, approx. 10% more jumbo runner seed (riding a 8.33 by 19.05 mm slotted screen), significantly lower oil content (45% vs 49%), and significantly higher oleic to linoleic fatty acid ratio (3.1 vs 2.3) than C-99R. Not significantly different from C-99R in number of sound mature seed count, blanchability, protein content, and roasted peanut flavor scores.
