Abstract

Aim: The aim of this study was to determine the magnitude of G x E interaction and to identify high yielding and stable or specifically performed genotypes for target environment(s).

Materials and Methods: A total of 14 faba bean genotypes including the standard and local checks were evaluated at eight locations during main cropping season. The genotypes were arranged in Randomized Complete Block Design and replicated three times. Combined ANOVA, AMMI and GGE bi-plot models were used to analyze the data.

Results: AMMI and GGE biplot analyses result identified that genotypes (EH03071-1-2006) and (EH99005-2-2005) were declared as widely adapted genotypes with likewise recorded higher grain yield of 4.96 tons/ha and 4.90 tons/ha, respectively. Both genotypes EH03071-1-2006 and EH99005-2-2005 were superior to the standard checks with grain yield advantage of 18.66% and 17.22%.

Conclusion: It was concluded that genotype by environment interaction and stability measuring trials helps to identify genotypes with both high performance and grain yield stability.
