STABILITY IN SEED YIELD OF FRENCH BEAN (PHASEOLUS-VULGARIS) GENOTYPESIN HIGH-HILL, DRY TEMPERATE REGION OF NORTHWESTERN HIMALAYAS

A set of 24 genotypes of french bean (Phaseotus vulgaris L.) grown in 3 distinct environments (Sangla. Kukumseri and Leo) in dry temperate r egion for 2 years was studied for stability in yield. Stability perfor mance analysis in 6 environments revealed significant differences due to genotypes. environments and genotypes x environment (G x E) interac tions. Both linear and nea-linear components of G x E interaction were present, with predominance of the former component. The genotypes sho wing wide adaptability and specific adaptation were identified. 'KRC 5 '. 'KRC 8' and 'KRC 11' were observed high yielding, out of which 'KRC 8' proved widely adaptable.
