Abstract
An investigation was conducted to evaluate the productivity of 11 chickpea genotypes alongside three checks, across three distinct locations within Chhattisgarh state i.e. Raipur, Kawardha and Ambikapur. Significantly varied responses were observed among the genotypes, environments and their interactions (GxE interaction), highlighting the substantial impact on yield outcomes. Utilizing stability parameters recommended by Eberhart and Russell, AMMI, GGE Biplot and WAASBY analysis, genotypes G11 (RG 2017-106) and G8 (RG 2017-36) were identified as stable performers with high yield potential across all locations. Kawardha location emerged as the most favourable location for these genotypes, followed by Raipur, while Ambikapur was concluded to be unfavourable location for these genotypes.
