The present investigation was carried out with fifteen coloured capsicum genotypes grown at three locations during Kharif 2018. Pooled analysis of variance over three environments revealed highly significant differences among genotypes for all the characters. The environment E1 was the most favourable environment for the expression of all traits. The pooled analysis of variance for stability revealed significant variation among genotypes for all traits. Environments (linear) component of variance was significant for all traits. The linear component of genotype × environment was also significant for all traits. The estimates of regression coefficients for fifteen genotypes ranged from 0.46 to 2.16 for days to first flowering, 0.56 to 1.43 for days to first fruit set, 0.18 to 1.76 for days to first harvest, -0.26 to 3.05 for number of fruits plant-1, 0.24 to 1.91 for average fruit weight, 0.24 to 2.15 for average fruit yield plant^-1 and 0.23 to 2.13 for fruit yield plot^-1.
