The field experiment was conducted in two locations i. e.Pawe and Assosa from 2016-2018 main cropping seasons withthe main objectives of identifying high yielding and disease resistant GSR lines in the lowland production system. A total of 20 genotypes including two checks were used for the study.The combined analysis revealed that no genotype significant difference than the standard check on grain yield. This revealed that the tested genotypes failed to give high grain yield than the standard check (KOMBOKA) and there is no genotype for wider adaptability. The mean grain yield ranged from 2730.30kgha-1(G7) to 3683.40 kg ha-1 (G13). Even though all tested genotypes failed on combined analysis for both locations, the separate location combined analysis revealed that there is a significant difference on grain yield and other agronomic characteristics than the standard check. The separate location combined analysis revealed that there is a significant difference on grain yield and other agronomic characteristics than the standard check. In Assosa, one genotype (G13) and in Pawe two genotypes (G14 and G1) revealed a significant differences than the standard check and gave grain yield advantage of 26.7%, 21.7% and 20.6%, respectively than the check.
