Abstract: Horse gram being highly drought tolerant crop and having nutritionally rich grains, plays major role in climate change resilient agriculture and forms potential food source for future. However, work on genetic improvement is meagre and it needs to be strengthened. Therefore, present investigation was carried out to assess the genetic variability, genetic diversity and associations among 111 horse gram germplasm lines for various qualitative and quantitative traits, and to study varietal differences for plant nitrogen content, and grain nutrients content (protein, calcium, iron and zinc) among 21 genotypes. Based on D2 values, the genotypes were grouped into 16 clusters. Cluster II was the largest comprising of 51 genotypes, followed by cluster I (21 genotypes), Cluster III (19 genotypes) and cluster XII (8 genotypes). The remaining 12 clusters were solitary. Inter cluster distances ranged from 3.77 to 24.89. Highest inter cluster distance was obtained between cluster III and IX. Among the traits, days to maturity contributed highest (71.20 %) towards the genetic divergence. The genotypes of solitary clusters which secured overall high ranking across thirteen characters were GPM 65, GPM-03, 12B, BHGM-26 and BHL-15. Genetic variability studies revealed high GCV and PCV estimates observed for number of pods per plant, high heritability and genetic advance for days to 50% flowering and days to maturity. Correlation analysis revealed positive and highly significant association of seed yield with pod weight per plant, 100 seed weight and pod length, and highly significant negative association with days to 50% flowering. Nutritional quality analysis revealed the range of values for grain micronutrients viz., calcium (38.43-104.812 mg/100g), iron (0.39-7.083mg/100g), zinc (0.966-5.467 mg/100g), and grain protein (17.21 to 25.63%) and plant nitrogen (0.69 to 1.33%) contents.
