Principal component analysis, genetic variability studies were performed in pigeon pea germplasm lines to study the genotypic responses, characters associations and environmental interactions towards transplanting responsiveness for yield and yield attributing traits. Short duration (120-145 days) photo insensitive types did not show significant differences on seed yield and attributing traits. Medium duration types (above 145 days) showed moderate to poor responses. Even in long duration types, perennial vegetable types, vegetable types showed greater levels of adaptation followed by grain types. Yield attributing traits like plant height, number of branches, number of pods, and number of seeds were highly associated with seed yield under transplanting responsiveness
