Background: Redgram is an inexpensive source of protein for vegetarians that is grown in dry and semi-arid tropical regions around the world. Genetic improvement is mostly determined by the amount of genetic variability available in the population. To create an efficient breeding program, a breeder must first understand the extent of genotypic and phenotypic variation in the germplasm.

Methods: Sixteen Redgram genotypes were tested for variability in yield and yield-related characteristics. The experiment was carried out at the Agricultural Research Station in Darsi during 2024 to 2025 in a randomized block design with two replications.

Result: Given their average performance, TRG 47, TRG 59, LRG 721, and TRG 59 were recognized as elite genotypes for increasing yield and nutritional quality. The features with the highest PCV and GCV estimates were the number of primary branches per plant (21.61, 20.12%), the number of secondary branches per plant (36.70, 35.33%), and the yield per plot (27.81, 24.71%). This suggests that there is a significant degree of variation in these features, making selection of these traits successful. High heritability paired with high genetic progress was observed for the variables viz., number of primary branches per plant, number of secondary branches per plant, number of pods per plant, and yield per plot, showing the presence of additive gene action and can be improved by phenotypic selection. The traits initial plant height, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, and 100 seed weight all showed a significant positive relationship with yield, indicating that direct selection based on these traits would be beneficial for increasing yield in redgram.
