Abstract: (2369 Views)
Spot blotch disease of barley caused by Cochliobolus sativus, is an important barley disease which causes extensive grain yield losses. In order to understand the inheritance of resistance to the disease, an experiment was conducted using seven barley genotypes in partial diallel crosses. Parents and F1 crosses were planted in a randomized complete block design (RCBD) with three replicates. The severity of disease was recorded as the first signs of disease and then AUDPC was calculated. D and H components showed that both additive and dominance effects are effective in controlling the traits. Dominant alleles led to a reduction in the severity of disease and increased resistance to spot blotch disease. 67/110 and sahra genotypes have negative GCA and can take advantage of them as promising parents in breeding programs for resistance to the disease.
