“…The high-oleic, small-seeded, runner-type peanut cultivar Georgia-13M had the highest dollar values at the two Georgia locations for both the four and five-years (Tables 4 and 7). The results from this study would suggest that Georgia-13M, Georgia-06G, and Georgia-12Y each have better combined disease resistance and drought tolerance than the other runner and virginia-type cultivars which agrees with a previous report for Georgia-06G having the greater dollar value return in both maximum and minimum tests (Branch and Fletcher, 2010). Performance of these three cultivars when grown with minimum-inputs and without irrigation should have major potential impact for dryland peanut production, and demonstrates significant improvement in cultivar development over an earlier report by Branch and Fletcher (2004).…”

With increasing production cost, southeast U.S. peanut (Arachis hypogaea L.) growers are continually seeking to lower inputs to enhance economical return and sustainability of their farming operation. Utilization of peanut cultivars with the best combination of disease resistance, drought tolerance, and greatest dollar value return would be beneficial. Fifteen peanut cultivars were evaluated for 5-years (2011–15) and seventeen cultivars were evaluated for 4-years (2012–15) with minimum inputs and without irrigation at two locations in Georgia. Each year, minimum inputs for disease control included only three fungicide sprays at recommended rates on a 28 d schedule beginning 37 d after planting. No insecticide, nematocides, miticides, or irrigation were applied during the growing seasons each year. ‘Georgia-06G', ‘Georgia-12Y', ‘Georgia-13M', ‘Georgia-14N', and Florida-EP ‘113’ had the lowest TSWV and total disease incidence (disease resistance) among the ten runner-type cultivars for both Georgia locations; whereas, ‘Bailey', ‘Georgia-08V', and ‘Georgia-11J' had the least disease incidence among the five virginia-type cultivars. Similarly, Georgia-13M, Georgia-06G, and Georgia-12Y had the greatest gross dollar value return per hectare (drought tolerance) among the runner-types; whereas, Georgia-08V and Georgia-11J had the greatest dollar values per hectare among the virginia-type cultivars at both Georgia locations in this four and five-year study, respectively.

“…These results agree with a previous 3-yr maximum and minimum production input study for TSWV disease resistance (Branch and Fletcher, 2010). Again at both mid and late-season, TSWV and CBR incidence was found to be the lowest with Georgia-07W, Georgia-06G, Georgia Greener, and Georgia-10T.…”

Cylindrocladium Black Rot (CBR) caused by Cylindrocladium parasiticum Crous, Wingfield, & Alfenas syn. C. crotalariae (Loos) Bell & Sobers is a major disease problem in southeast U.S. peanut (Arachis hypogaea L.) production. Field trials were conducted for two-years (2008-09) at a test site (Gibbs Farm) that has a long history of continuous peanut production near the Univ. of Georgia, Coastal Plain Expt. Station, Tifton, GA to evaluate for CBR resistance among new runner-type peanut cultivars. All plots were artificially inoculated with microsclerotia of C. parasiticum after planting each year. Significant differences (P≤0.05) were found among the cultivars and advanced breeding lines for both CBR resistance and tomato spotted wilt virus (TSWV) resistance which was also present each year, but the predominant disease was CBR. Georgia Greener, Georgia-06G, Georgia-07W, Georgia-02C, and Carver were consistently found to be the most CBR resistant; whereas, C-99R and Tifguard were the most susceptible each year. In separate CBR tests conducted in 2009 and 2010 at a different location (Blackshank Farm), Georgia Greener also had the least difference, and Tifguard had the greatest difference, between C. parasiticum inoculated versus non-inoculated plots for pod yield. These combined test results demonstrate that useful levels of CBR resistance are currently available in promising new runner-type peanut cultivars.

“…The performance results also show the benefit to growers from agronomic and economic improvement with many of the newly released peanut cultivars in Georgia. (W. D. Branch and S. M.

The project involves a mixed methods approach to the research as it involves field experimentation and will examine not only the quality of the plants but the quantity of the yield of several one acre plots, each sown with a different variety for a minimum of 2,000 pounds per acre without the use of growth promoting chemicals to include herbicides, pesticides and insecticides. Three different peanut varieties will be utilized in the study; GA-06G, GA-12Y, and Florrun 331.
