Abstract
Groundnut leaves, naturally infected in the field by C. arachidicola [Mycosphaerella arachidis] or artificially infected in the greenhouse with C. arachidicola or Puccinia arachidis, accumulated isoflavonoid phytoalexins. Major compounds included medicarpin, formononetin, demethylmedicarpin, 3 isoflavanones and the isoflavone daidzein. In both greenhouse and field experiments, cv. Egret was less susceptible than cv. P84/5/244 to both pathogens and accumulated phytoalexin (medicarpin) concn which were up to 3 times greater. Higher concn and greater variation of phytoalexins were detected when both cultivars were infected with M. arachidis than P. arachidis
