Resistance of Peanut Germplasm to Sclerotinia sclerotiorum¹

Authors: , ,


Several peanut cultivars, breeding lines, and plant introductions were screened in the field for susceptibility to Sclerotinia blight, caused by Sclerotinia sclerotiorum. Differences in susceptibility ranged from slight to severe. Of the cultivars screened, Florigiant appeared to be the most resistant to S. sclerotiorum. Florigiant and NC 17165 pod yields were significantly greater and plants were killed less frequently than plants of other cultivars. Breeding lines with Spanish and Valencia pedigrees were more resistant to S. sclerotiorum than Florigiant.
