Title
Genotype environment interaction and stability of chickpea for seed yield at dry areas
Authors
Abstract
Chickpea (Cicer arietinum L.) is a valuable source of protein and has an important place in rotation
with cereals. Study on genotype enviroment interaction (GE) and stability of twenty two chickpea genotypes were conducted for grain yield at two locations during three successive years (2010-12). The objectives of the experiment were to determine the magnitude of GEI and stability of released and elite chickpea genotypes and thereby identify widely and/or specifically adapted genotypes under Kurdistan province conditions. There are strong significant (P≤0.01) environment, genotype and GEI effects, and environment and GEI captured larger portion of the total sum of squares, which reveals the influence of the two factors in evaluating chickpea genotypes and, hence, the need for stability analysis. Three most popular stability parameters were used for stability analysis. Two genotypes that had medium yield performance, ILC 482 and ILC 8617 were identified as stable genotypes for grain yield. The top yielding genotypes, Sel93Th24460 was found less stable and can be recommended for narrow adaptation to Saral district.
