The presence of variation in a population is key to select desirable plants for further improvement. The experiment was done to assess the 135 germplasm derived from four crosses along with four checks GNIB-21, GNIB-22, V-19-154 and W-19-58 were grown in augmented block design. Analysis showed significant genotype mean square values for all the traits except pods per raceme. In the present investigation, based on per se performance V-19-78, V-19-107, V-19-111 and V-19-115 were identified as promising genotypes in the current study because they had higher grain yields per plant. Selection for determinate growth habit with high yield potential can help in mechanized harvesting in lablab bean. These genotypes could be further examined in order to identify attributes that lead to higher yields, early maturity and better yield. Based on all of the research, it can be said that racemes per plant is the most significant trait in Indian bean seed yield. As, this trait showed higher estimates of GCV, PCV, h2(bs) and GAM.

According to the studies mentioned above, racemes per plant, pods per raceme, pods per plant and seeds per pod are the most crucial component characters for increasing grain yield per plant; as a result, these traits should be taken into consideration when choosing parents for breeding programme aimed at increasing seed yield in Indian beans.
