Abstract

Four advanced lines of WHEAT which had appeared to be resistant to YELLOW RUST in past years, along with the susceptible cultivar Bolani were intercrossed in one-way diallel cross. Seedlings were grown in greenhouse until the first leaves fully expanded and then inoculated with two pathotypes (race) 6E130A+and 166E42A+of YELLOW RUST, separately. INFECTION TYPEs were scored 18 days after inoculation. DIALLEL ANALYSIS was done by two methods of Griffing, and links and Hayman. Results of analysis of variance of Wr + Vr and Wr - Vr, regression analysis of Vr and Wr and estimates of genetic parameters indicated the importance of additive and dominance effects with pathotype 6E130A+ and importance of additive, dominance and epistatic effects with pathotype 166E42A+. Broad-sense and narrow-sense heritability of INFECTION TYPE were estimated 97% and 58% for pathotype 6E130A+and 99% and 81% for pathotype 166E42A+, respectively. Line M-78-16 possessed the greatest general combining ability to decrease INFECTION TYPE and therefore was suggested to be included in breeding programs for resistance to YELLOW RUST.
