Abstract

Inheritance of resistance to YELLOW RUST disease in bread WHEAT was studied using a GENERATION MEAN ANALYSIS. The study material comprised six generations (susceptible and resistant parents, F1, F2, BC1 and BC2) in two crosses. Seedlings were grown in greenhouse until the first leaves were fully expanded and then inoculated with two path types (race) of YELLOW RUST (6E134A+ and 134E148A+) separately and infection type and latent period were recorded. Results of GENERATION MEAN ANALYSIS and segregation ratios in F2 population indicated the significance of non-allelic interactions beside additive and dominant gene effects in INHERITANCE of resistance to YELLOW RUST. Dominant and dominant x dominant gene effects were significant in genetic control of infection type. The direction of dominance for infection type was different depending on the cross and the race in the experiment. Broad-sense and narrow-sense heritability of infection type were medium to high and medium respectively. Additive gene effect was significant in genetic control of latent period. Broad-sense and narrow-sense heritability of latent period were medium.
