A standard multi-factor analysis of variance showed the main effect due to years, locations and first order interactions (year x location) were highly significant. The main effect for genotype, first order interaction (varieties x locations), (variety x year) and second order interaction (varieties x locations x year) were highly significant. The highly significant interactions indicate that varieties need to be tested in severe years and locations in order to select stable variety. The IPCA 1 and IPCA 2 axes also found highly significant (P<0.01). Partitioning of the variance component (%) indicated that 14.21% due to varieties, 39.50% due to environments and 46.29% due to GEI. According to the AMMI stable value give, the chickpea varieties JG-226 (0.67), JG-130 (1.03) and Vaibhav (1.33) were the three most stable varieties with higher than grand mean yield, all these chickpea varieties were early maturing. Portrait shows the JG-14 (G4) exhibited specific adaptability for environments: E1, E2, E3, E7, E8 and E9 with grain yield less than mean. As the varieties and environments of first adaptive group have the same sign on the IPCA axis, their interaction were found positive. Varieties JG-63 (G6), JG-130 (G8), JG-226 (G9), Vaibhav (G10), JAKI-9218 (G11) and Vishal (G12) (adaptive group 2) revealed specific adaptation for environments E10, E11 and E12 with high grain yield, more than mean yield and positive interaction.
