“…Okrun is a peanut cultivar that was released in 1980s [32] while ARSOK-R1 is an advanced breeding line under development for variety release [33]. Okrun, classified as the runner variety, results from the cross of Florunner and Spanhoma [32]. Both lines, Okrun and ARSOK-R1, were planted in the test plots of the Oklahoma State University Agricultural Experiment Station in Ft. Cobb, Oklahoma around May 15, 2006 and harvested around October 15, 2006.…”

This study has shown for the first time the suitability of CE with a partially aqueous electrolyte system for the analysis of free fatty acids (FFAs) in small portions of single peanut seeds. The partially aqueous electrolyte system consisted of 40 mM Tris, 2.5 mM adenosine-5'-monophosphate (AMP) and 7 mM alpha-CD in (N-methylformamide) NMF/dioxane/water (5:3:2 by volume) mixture, pH 8-9. While AMP served as the background UV absorber for indirect UV detection of the FFAs, the alpha-CD functioned as the selectivity modulator by affecting the relative effective electrophoretic mobilities of the various FFAs due to their differential association with alpha-CD. This CE method allowed the screening of peanut seeds for their content of oleic and linoleic acids, which is essential in breeding of peanuts of high-oleic acid content. The extraction method of FFAs from peanut seeds is very reproducible with a high recovery approaching quantitative yield (approximately 97% recovery).

“…Six runner peanut genotypes were used to compare the three inoculation methods: the resistant cultivar Georgia-03L (Branch, 2004;Woodward et al, 2006) and breeding line ARSOK-R35 Chamberlin, 2014, 2015); moderately resistant cultivars Red River Runner (Melouk et al, 2012) and Tamrun 96 (Smith et al, 1998); and susceptible cultivars Okrun (Banks et al, 1989) and Tamrun OL02 (Simpson et al, 2006). Two seeds each were planted into a commercial potting soil (Metro-Mix 350, Sun Gro Horticulture, Agawam, MA) in 11 cm diam.…”

Three Inoculation Methods for Evaluating Sclerotinia Blight Resistance in Peanut

2016

Laboratory-based assays for screening germplasm for resistance to Sclerotinia blight in peanuts can be conducted year-round, and thus may accelerate progress in breeding for resistant plants. Three previously proposed inoculation methods (using main stems of intact plants, detached main stems, or detached leaflets) were compared on six peanut genotypes known to represent range of resistance to Sclerotinia blight in the field or laboratory. The intact plant and detached main stem assays identified the most resistant and susceptible genotypes, but different results were obtained from either assay with Red River Runner, a cultivar with intermediate resistance to Sclerotinia blight. No differences among genotypes were observed with the detached leaflet assay. The sensitivity ratio was used to compare the three inoculation methods and identified the intact plant assay as the method with the smallest error variance. These results help identify the most efficient method for assaying physiological resistance to Sclerotinia blight in peanut.

“…Southwest Runner is a runner market-type peanut cultivar with moderate resistance to S. minor comparable to Tamspan 90 (Kirby et al, 1998). Okrun was included as a susceptible (Banks et al, 1989). Flavor Runner 458 is a Sclerotina blight susceptible high oleic runner type cultivar (Horn et al, 2001).…”

Planting Density Influences Disease Incidence and Severity of Sclerotinia Blight in Peanut

Sclerotinia blight, caused by Sclerotinia minor Jagger, has become one of the major limiting factors in peanut (Arachis hypogaea L.) production. The objectives of this research were to evaluate the effects of plant spacing on disease incidence and severity of Sclerotinia blight in peanut research plots, to measure the level of apparent resistance at different seeding rates, and to determine which methods would produce clearest selection criteria in space-planted breeding plots. Four peanut cultivars, Tamspan 90, Southwest Runner, Okrun, and Flavor Runner 458, were evaluated in field plots at four plant spacings (6, 15, 30, and 46 cm) in 2003 and 2004. Increased plant spacing improved sensitivity of disease incidence based determination of cultivar resistance but did not increase mean incidence significantly. Disease severity reached the highest level at the widest plant spacing. Final disease incidence provided excellent differentiation of genotypes with different levels of resistance and required the least amount of labor as compared with other methods of disease assessment.A.L.
