Forty-two lines of chickpea (Cicer arietinum Linn) including two checks grown during winter season (rabi) for three years 1988-89, 1989-90 and 1990-91 in twelve environments were evaluated for stability parameters of Chhotanapur regions. Pooled analysis of variance revealed that the mean sum of squares due to genotypes and environment for primary branches/plant, secondary branches/plant and grain yield/plant (g) found highly significant ( except primary branches /plant) indicating presence of high variability among the genotypes and environment. Environmental (Linear) was found highly significant for all the characters which indicated variation in weather condition of the location. The pooled deviation (non-Linear portion of the variance) was found highly significant for all the characters. The environment+ (Genotypes x environment) interaction were found highly significant, showing important role of environment and genotype x environment interaction to these characters. Considering all the characters the genotypes ICCL86309, ICC11141, ICCL84204, ICCL 85211, ICCL86211, ICCL87208, ICC5003,ICCL85307 having bi= 1 and S2 di = 0 found highly promising for average yielding environment. While genotypes ICCL 84303, ICC5003 having bi>1 and S2 di= 0 found promising for richer environment. For poor environment genotypes ICCL 86226, ICCL87233 having bi<1 and S2 di= 0 found promising.
