Phenotypic stability for seed yield in pigeonpea

Ten genotypes of short duration pigeonpea were grown in four environments and seed yield data analysed for stability parameters. Highly significant mean squares were observed for genotypes, genotype X environment interaction and environment (linear). ICPL 151 wu the most stable genotype under rainfed conditions of Doon Valley u it had high mean. regression coefficient not deviated from unity, and non significant minimum deviation from regression.
