Abstract:
The phenotypic stability of nine recombinant inbreed lines of French bean were tested for growth and yield components by growing them in four different environments. Results revealed highly significant difference among the genotypes for all the traits studied except for pod weight, days to 50 percent flowering and days to maturity. Significant variation among the environments was observed for almost all the characters studied except for pod weight and days to maturity. Genotype x environmental interaction were significant for pod length, pod weight and green pod yield per plant, which indicates differential performance of genotypes under different environments. Among the recombinant inbreed lines tested for stability, inbreed line, 6-1 had maximum green pod yield per plant and is most stable over different environments with high mean values, regression coefficient around unity and non-significant deviation from regression.
