Tartary buckwheat (TB; Fagopyrum tataricum Gaertn.) is a nutritional, multigrain crop. Increasing population pressures, urbanization, and the dissolution of traditional culture have led to a sharp fall in Tartary buckwheat landrace coverage. Morphological and molecular diversity of 43 Tartary buckwheat genotypes were assessed based on 9 morphological traits of plants and 59 simple sequence repeat (SSR) markers, respectively. The analysis was done with standard statistical procedures, Mahalanobis D2 statistics and principal component analysis were used for the morphological analysis. Molecular analysis was done using NTSYS-pc software. Analysis of variance revealed that there is adequate genetic variation for all traits. High genotypic correlation coefficients (GCV) and phenotypic correlation coefficients (PCV) was observed for seed yield per plant. High heritability coupled with high genetic advance was observed for seed yield per plant. Correlation analysis revealed that seed yield per plant had positive correlation with days to 80 % maturity. Path analysis revealed that direct positive effects of plant stand at harvest followed by plant height towards seed yield per plant. Based on the polymorphism displayed by SSR markers, a dendrogram was developed and forty-three genotypes were grouped into four clusters. Data for diversity from the morphological and molecular analysis were found to be similar. On the basis of divergence studies, following genotypes viz., IC-329393, IC-42418 and IC-107605 were found most promising for future hybridization programs. On per se performance, the highest-yielding genotype was IC-42418, genotype IC-341591 had the highest crude protein content and the genotype IC-318859, was found to be superior for most of the traits.
