The present study carried out with the objective to evaluate and identify stripe rust resistant bread wheat genotypes conducted using lattice design under natural epidemic conditions in 2021 main cropping season at Kulumsa and Meraro,South Eastern Ethiopia.Slow rusting resistance was assessed using both disease and yield and yield trait parameters. Highly significant(P<0.01) differences were noted among the 100 tested genotypes for most parameters noted above.Except genotype 231237(62.013q/ha),none of the rest tested genotypes sustained better disease reaction and grain yield than MR check Wane (61.012(q/ha).On the other hands,seven genotypes Kingbird (48.05qt/ha), 6883 (48.5qt/ha),235038 (50.21qt/ha), 231487 (49.99qt/ha), Huluka (48.47qt/ha), 20411 (44.49qt/ha, 226283(44.3qt/ha) over yielded MS check Dursa (43.88qt/ha .Genotypes with MR reaction and MS reaction and gave yield better than Dursa are recommended for yellow rust resistance breeding and yield improvement.
