Abstract :

The purpose of this study was to identify genotype of high yielding and stable types in different environmental conditions. The experiment was conducted using eighteen chickpea genotypes in randomized complete bloch design with three replications in four agricultural research stations i.e. lorestan Ilam,gachsaran and Gonbad ,two successive cropping seasons (2014-2016) in autumn planting under rainfed conditions. The highest average seed yield (2911.5 kg.ha-1) was obtained at Lorestan in 2015 -16 and the lowest (742.9 kg.ha-1) was at Ilam in 2014-15. The highest and lowest average seed yield obtained in G2(1509.4 kg.ha-1) and G13 (1266.3 kg.ha-1), genotypes, respectively.The contribution of E, G, and GEI to the total variation in seed yield was about 87.7%, 0.65 % and 11.64%, respectively. The GEI was partitioned using GGE biplot model. According to singular value partitioning, the first two principal components explained PC1=36.6% and PC2=19.5% of total variations in data of seed yield. On the basis of GGE biplots, G2, G6 and G12 had high seed yield and yield stability as compared to the other genotypes.Genotypes G2,G17,G12,G4 and G6 were stable genotypes .On the other hand , genotype G2 had higher seed yield and , on the other hand , showed higher yield stability and was showed to be superior genotype compared to other.
