Studies on the susceptibility of peas and field peas cultivars to Phoma medicaginis var. pinodella (Jones) Boerema

Abstract

The aim of the work was to find the plants resistant to <i>Phoma medicaginis</i> var. <i>pinodella</i> causing leaf spot-pot of peas and field peas. Fourty five cultivars of peas and field peas and 6 breeding materials were tested in field in the period 1975-1978 on artificially inoculated field plots. Cultivars: Jubilat, Paloma, Proteus, Uladowskij Jubilejnyj, Fioletowa, Nieznanicka and Rosacrone were to be less susceptible. In laboratory and greenhouse conditions peas and field peas cultivars were examined for susceptible to pathotypes 3 and 5 of <i>Phoma medicaginis</i> var. <i>pinodella</i>. The results obtained proved that cultivars: Auralia, Finale, Flavanda, Jubilat, Paloma, Proteus, Uladowskij Jubilejnyj, Nieznanicka and Rosacrone were to be less susceptible to two pathotypes of <i>P. medicaginis</i> var. <i>pinodella</i>
