Tef (Eragrostis tef [Zucc.] Trotter) is a tiny-seeded cereal with huge importance in Ethiopia. Creation of variability by hybridization and the subsequent selection of RILs is very important towards variety development. In order to identify superior tef genotypes, evaluation of RILs was performed on eight environments using three times replicated randomized complete block design. The result revealed that genotypes (G), environments (E) and genotype-environment interaction (G×E) significantly (p
