    Variation in Phytoalexin Production by Peanut Seed from Several Genotypes¹

Abstract

Evaluation of twenty peanut (Arachis hypogaea L.) genotypes for their phytoalexin producing ability showed wide variation in the amount and composition of phytoalexins produced. Some genotypes produced one major phytoalexin component while the other genotypes produced seven major phytoalexin components. In addition, high phytoalexin producing genotypes utilized more methionine-rich protein than the low phytoalexin producing genotypes suggesting that methionine-rich protein or its breakdown products may have a role in phytoalexin production.
