Abstract

Genotype by environment interaction (G×E) obstructs breeding by persuading variations in genotype performance in different environments and thereby complicating selection. The aim of the present study was to determine the stability and yield performance of desi type chickpea varieties and advanced lines at multiple growing environments of western Ethiopia, using genotype-by-environment interaction (GGE) biplot analysis and AMMI model to find stable high yielding cultivar(s) and ratify for wider production. The experiment was laid out in a randomized complete block design with three replicates. The analysis of variance (ANOVA) indicated highly significant differences (P≤0.01) for environments, genotypes and importantly genotype by environment interaction (G×E). Additive main effects and multiplicative interactions (AMMI) and GGE biplot, AMMI Stability Value (ASV) and Genotype Selection Index (GSI) indices indicate that Natoli (G8) variety and DZ-2012-CK-20113-2-0042 (G16) advanced lines showed better grain yield with better stability across environments and thus are recommended for wider production in test locations and similarly agro-ecologies in Ethiopia.
