Chickpea (Cicer arietinum L.) is generally grown-up underneath rainfed conditions inside the Barind space in Bangladesh, any place drought spell is that the principle production constraint. Genotype × Environment Interaction (GEI) was acclimated with making estimation of the grain yield and to get a handle on the G × E connection designs by analyzing the differential positioning of choice yields in multi-condition trials. Twelve chickpea genotypes were conveyed in a randomized block design with three replications in six conditions. The solidness of the evaluated genotypes utilizing three kinds of factual thoughts (variance and regression analyses), AMMI investigation and GGE biplot models were applied to get a reasonable comprehension of the connection and covering among the pre-owned soundness insights. The partition of the full aggregate of squares demonstrated that the mood result was a genuine gracefully of variation (64.84%) trailed by GE relations (24.88%) and germplasm result (10.29%). The genotype by environment collaboration biplot clear that genotype G4 is that the perfect genotype, though genotypes G6 and G8 were closest to the best genotype (the focal point of concentric circles); in this way, these genotypes square measure extra intriguing and perfect genotypes than various tested genotypes. Investigated condition ISD demonstrated reasonable segregating capacity and representativeness, making it the foremost perfect condition followed by GAZ. AMMI Stability Value (ASV) separated genotypes G2 (BCX 09010-9), G3 (BCX 09010-2) and G8 (BCX 01008-4) the steady accessions, respectively. GGE biplot investigation, AMMI and Eberhart and Russell model unconcealed that the GGE biplot examination results conjointly bolstered those got utilizing AMMI and various boundaries and ensure that G2 (BCX 09010-9) and G8 (BCX 01008-4) were the preeminent stable genotypes. G4 and G6 were conjointly high yielding, anyway incongruent and in this way should be suggested for affirmation and promising line for adjustment in specific environments. GGE biplot analysis, AMMI and Eberhart and Russell model unconcealed that the GGE biplot analysis result conjointly supported those obtained using AMMI and different parameters and make sure that G2 (BCX 09010-9) and G8 (BCX 01008-4) were the preeminent stable genotypes. G4 and G6 were conjointly high yielding, however incompatible and therefore ought to be recommended for confirmation and promising line for adaptation in specific environments.
