Abstract
The qualitative formation of pisatin by 58 named cultivars and nine numbered lines of P. sativum and P. arvense and three other species of Pisum following inoculation by Monilinia fructicola was established. Quantitative studies of pisatin formation using host[long dash]parasite combinations of several pea cultivars and several strains of Ascochyta pisi showed that where one strain of A. pisi was used to inoculate several cultivars of peas, the concentration of pisatin varied with the variety. On the other hand, where one pea cultivar was inoculated with several strains of A. pisi the concentration of pisatin was related to the strain of A. pisi.Keywords
