Twelve promising varieties of groundnut (Arachis hypoqaea L.) were evaluated for stability of performance for pod yield over nm environments in Egypt. Highly signif j- cant coefficient was detected for genotype and genotye x environment interaction. Significant bi values were obtained for all genotypes and the slope of the regression lines did not deviate significantly from unity in the varie ties L 404, L 447, NA 128, NA 219, NA 297 and NA 299. The deviation from regression mean sqars (S’ di) were significant for NA 128, NA 219, NA 242 and Giza 4. The highest yielding genotypes were, L 447, NA 268, Giza 4 and L 262. The variety L 447 had average stability and high level of performance for pod yield and hence it seemed to be an ideal variety in the material under study.
