Forty five hybrids of pigeonpea and their 18 parents were evaluated for stability analysis using Eberhart & Russell model. The mean square due to genotypes was highly significant for all the traits except branches per plant. This indicates presence of considerable genetic variability for most of the traits. The G x E interactions were significant for all the traits except protein content. This suggested that genotypes responded differently in changing environments. The mean square due to pooled deviation indicated that prediction of performance of genotypes over environments based on regression analysis might be unreliable. Parent ICPL 87119 and hybrid MCo 5 x P 185 and M 3783 x P 185 showed higher mean, unit regression and non-significant S'd, indicating their stable performance across environments
