| dc.description.abstract | Forty isolates of Ascochyta rabiei collected in Saskatchewan Canada and 18 obtained from other countries were assessed for pathogenicity on eight chickpea differential lines/cultivars under controlled conditions. Each assessment was repeated once. Based on the differential by isolate interactions, 15 distinct pathotypes were identified among the isolates from Saskatchewan. This demonstrates that many races of A. rabiei are present in Saskatchewan. Formation of new virulent races through gene recombination is possible. This will have large impact on Ascochyta blight development and its control. Plant breeders should anticipate a highly diverse A. rabiei population with a high potential for change. | en_US |
