Buckwheat is important indigenous crop of the Himalayan region because it can withstand cold temperature and acidic soil conditions. The present study was undertaken to assess the genetic variation, heritability, correlation, and direct and indirect effects of quantitative characters on seed yield in a set of diverse buckwheat genotypes during Kharif 2000 and 2001. Based on two years pooled data high PCV and GCV were observed for number of secondary branches, number of leaves and seed yield per plant and high heritability coupled with high genetic advance were observed for number of secondary branches, seed yield, number of leaves, number of primary branches and basal girth. Correlation as well as direct positive effect on seed yield, number of leaves, weight of 100 seeds, number of racemes, basal girth and days to maturity were the important yield contributing traits and hence could be relied upon as selection parameters for yield improvement in buckwheat.
