To study the heritability of resistance to stripe rust in bread wheat, F1, F2, BC1 and BC2 generations, derived from a cross between two wheat cultivars named Morvarid (resistant) and Bolani (susceptible) along with the parents, were evaluated under greenhouse condition, in a Randomized Complete Block Design (RCBD) with three replications. The seedlings were inoculated using the race 198E154A+ urediniospores. Components of resistance including infection type and latent period on single plants of generations were recorded. The results of weighted ANOVA showed that there were significant differences (p < 0.01) between the generations for two traits. Results of the generations mean analysis showed that additive; dominance and epistasis (especially additive × dominance and dominance × dominance) gene actions have a significant role in control of the traits. Furthermore, high broad-sense heritability was observed for these traits. The narrow-sense heritability was in an average range for infection type and was low for latent period. The number of segregating genes was estimated 1 - 2 for infection type and 1 - 3 for latent period.
