Abstract

Twelve peanut (Arachis hypogaea L.) genotypes of the Spanish botanical type and two of the Valencia botanical type were compared for reaction to the soil-borne pathogen, Cylindrocladium crotalariae (Loos) Bell & Sobers, that causes Cylindrocladium black rot (CBR) in peanuts. In Virginia, experiments were conducted in three fields (two in 1974 and one in 1975) with a history of severe CBR in previous peanut crops. The Spanish genotypes included all current cultivars grown commercially in the United States. Valencia genotypes (PI 355982 and 355987) were included as reference standards because of their known susceptibility to CBR.
