Abstract:
... Sclerotinia blight caused by Sclerotinia minor (Jagger) is a significant threat to peanut production; therefore varietal improvement toward this disease is needed. To date, there have been no reported quantitative trait locus (QTL) associated with Sclerotinia blight resistance in peanut. Hence, the objective of this study was to identify QTLs for Sclerotinia blight resistance. A total of 90 F₂:₆ r ...
