Peroxidase isozyme polymorphism in Cucurbita pepo cultivars with various morphotypes and different level of field resistance to powdery mildew.

Original language description

A set of 31 Cucurbita pepo L, commercial cultivars with different fruit shapes (morphotypes) was evaluated for resistance to powdery mildew of cucurbits (Erysiphe cichoracearum and Sphaerotheca fuliginea) under field conditions of a natural infection. During vegetative growth, the infection degree (ID) was assessed four times on leaves (L) and twice on stems and petioles (S). The 'Area below the: curve' values of the disease infection progress were calculated separately for leaves (ABC-L) and stems andpetioles (ABC-S). Data were subjected to one-way analyses of variance and mean separation was performed using LSD multiple range tests, Significant differences in field resistance were found between morphotypes. Cultivars with scallop and acorn fruit shapes were the most resistant. The straightneck, crookneck and ornamental gourd groups showed medium levels of field resistance. The zucchini, cocozelle, pumpkin and vegetable marrow groups of morphotypes were the most susceptible. Isozyme
