Race-specific response of Cucurbita germplasm to Pseudoperonospora cubensis

Popis výsledku v původním jazyce

The host range of Pseudoperonospora cubensis, the causal agent of cucurbit downy mildew, includes many taxa of the Cucurbitaceae. Little is known of the interactions of this pathogen with wild and weedy forms of Cucurbita, the genus encompassing two important crops, squash and pumpkin. Interactions of 97 germplasm accessions of wild and weedy Cucurbita spp. (gourd), derived from 10 species, with 11 P. cubensis isolates originating from Cucumis sativus were studied using a leaf-disc method under controlled conditions. Across the 97 accessions, 57 different reaction patterns were recorded; 15 accessions were resistant and 12 susceptible to all 11 pathogen isolates. A within accession, heterogeneous reaction was observed in only nine interactions. Of the 15 accessions resistant to all pathotypes, 13 were wild and weedy C. argyrosperma. Reactions of Cucurbita spp. to P. cubensis are race specific. The development of methodology for P. cubensis race determination and denomination should include a differential set of genotypes for each species separately. C. argyrosperma, which is partially cross-compatible with the economically important C. pepo, offers a potential source for breeding downy mildew-resistant squash and pumpkins.
