Technical Abstract: Peanut acreage in Oklahoma has declined in recent years; however, peanuts remain an important economic crop for certain growers. Yield limiting factors such as diseases, adverse weather conditions, weeds, and insects can decrease yield. Managing irrigation, chemical applications, and tillage practices are some of the avenues used to mitigate these yield-limiting factors, but often become cost prohibitive. Our peanut breeding efforts are focusing on enhancing yield and quality through breeding for disease resistance. Sclerotinia blight of peanuts caused by Sclerotinia minor results in about a 10% loss annually if not treated. Currently, about 40% of peanut fields in Oklahoma experience some loss due to Sclerotinia blight.
