Abstract: (2729 Views)
This study was performed to investigate and determine the virulence /avirulence spectra of five genes of wheat yellow rust disease collected from Karaj (174E158A +), Zarghan (103E16A +, Yr27), Sari (6E150A +), Sarakhs (Y72727 + A, Moghan (247E235A +). International standard and differential genotypes were used to determine the races of wheat yellow rust disease. Then, the response of 297 different bread wheat genotypes to these races was evaluated in a completely randomized design with two replications under greenhouse conditions and at a temperature of 15 ° C. In the study of correlation between different breeds, it was found that Sari (6E150A +) and Karaj (174E158A +) have the highest correlation. Also, simple analysis of variance for three traits of infection type, pustule size and pustule density showed high genetic diversity between the studied genotypes. Combined analysis of variance showed a significant effect of genotype, race and genotype-race interaction for infection type trait. The effect of genotype and race were also significant for pustule size and pustule density. The results of correlation analysis of traits in different races showed a significant and positive correlation between them. Cluster analysis divided the genotypes into three groups: resistant, semi-resistant (semi-susceptible) and susceptible, which confirmed the results of resistance reactions of wheat genotypes to different varieties of yellow rust. Based on cluster analysis, genotypes 6, 36, 39 and 44 had the lowest infection type (higher resistance) than all five races of yellow rust. The results of cluster analysis also showed the presence of commercial cultivars PARSI, KARAJ2, CHAMRAN2, PANJAMO62, MAHDAVI, PISHGAM, INIA66 and RIJAW in the group of resistant wheat, which can be obtained by using tree analysis to give the parent resistance to this disease.
