Abstract: The research was conducted during Kharif (2013) at Crop Improvement Research Block of Uttarakhand University of Horticulture and Forestry, Ranichauri Campus with 54 diverse genotypes of grain amaranth. The 54 genotypes including four checks viz., Annapurna, Durga, PRA-2 and PRA-3 were planted in an augmented design during under rainfed condition. Genetic variability and genetic divergence was studied for characters viz., days to 50% flowering, days to maturity, plant height, inflorescence length, spikelet length, number of spikelets per plant, stem thickness, 1000 seed weight and seed yield per plant. Analysis of variance reviled that differences among the entries were highly significant for days to 50% flowering, days to maturity, plant height (cm), inflorescence length (cm), spikelet length (cm), number of spikelets per plant, stem thickness (mm) and non significant for 1000 seed weight (g) and seed yield per plant (g). Adjusted mean for earliest flowering (63.20 days) and maturity (128.00 days) minimum in Durga. The maximum plant height (148.00 cm) was noticed in IC-95339. The genotype IC-82625 recorded highest seed yield per plant (46.69 g). Using the Non-hierarchical Euclidean cluster analysis, the 54 genotypes were group into eight different non-overlapping clusters. The highest inter cluster distance was observed between cluster III and cluster VIII (67.39) followed by cluster IV and cluster VII (64.30) suggesting wide diversity among these groups. Considering cluster mean and genetic distance, crossing between genotypes of cluster IV (IC-82625 and IC-95247) with cluster VIII (Durga) were likely to recombine the genes for high seed yield in temperate conditions mid hills of Uttarakhand.
