Abstract

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.
