Interactions of Cucumis melo and Cucurbita spp. accessions with Pseudoperonospora cubensis are race- (pathotype-) specific

Popis výsledku v původním jazyce

Cucurbitaceous vegetables are seriously affected by Pseudoperonospora cubensis, the causal agent of cucurbit downy mildew. Experiments focused on deciphering variation in interaction of 115 accessions of Cucumis melo (melon) with 8 isolates of P. cubensis representing 8 distinct pathotypes, and of 97 accessions of wild and weedy Cucurbita spp. (gourd) to 11 P. cubensis isolates, were carried out under controlled conditions. Within the melons, 45 different reaction patterns were recorded. Most of the melon accessions (67) were highly susceptible to all isolates. The reaction of 46 accessions was clearly race- (pathotype-) specific. None of the screened melon accessions expressed complete resistance to all isolates. Accession PI 315410 from India was resistant to 5 isolates and incompletely resistant to 2 others. Within the melon populations from India and southern Africa, there are accessions completely or incompletely resistant to various European races of P. cubensis. Within the Cucurbita accessions (representing 10 species), 57 different reaction patterns were recorded; 13 accessions were completely resistant and 12 completely susceptible. Wild Cucurbita argyrosperma has potential field resistance to a number of races of P. cubensis. This study established the background for future development of methodology for P. cubensis racial determination and denomination.
