Forty genotypes of egg-plant were tested, under six different environments for two seasons in a randomized block design with three replications, for their stability in performance for five different traits. To assess the stability of different genotypes, the models given by Finlay and Wilkinson and Eberhart and Russell were used. The mean squares for genotypes and genotype × environment interaction were significant for all the characters. The linear component of genotype × environment interaction for all the characters except the number of days taken to first flower was found to be significant. The deviations from linear response were found significant for all the characters except total yield and number of fruits per plant. High mean yields were given by the genotypes Barasati Round Selection, T-3, K.K.-3, Pusa Karanti, S-16, Rainy Round Purple, Japanese Long Maromarket Prize, S-373, R-34 and Early Long. The genotypes Barasati Round Selection and K.K.-3 proved to be most stable for total yield per plant. Genotype T-3 was found to be specifically suited to high yielding environments.
