Abstract: The article presents results of studying a collection of determinant buckwheat (Fagopyrum esculentum Moench) genotypes in the East of Ukraine. The purpose of the study was to select highly productive and stress-resistant genotypes for breeding. We noted a considerable variability of biometric and agronomic characteristics between genotypes. The highest productivity (3.2 g/plant) was recorded for accession UC0101058 (UA) and the highest thousand-kernel weight (37.4 g) was recorded for accession UC0100286 (BY). There was a strong positive correlation between the number of kernels per plant and productivity (r = 0.93). Using multivariate statistics methods, we distinguished major clusters of genotypes. Promising accessions (UC0100167 (UA), UC0101058 (UA), and UC0102186 (UA)) were selected for further breeding. Using principal component (PC) biplot analysis, we evaluated genetic relationships between the studied accessions and genetically distant genotypes (UC0101058 (UA), UC0100286 (BY), and UC0100963 (UA)) were identified as potential outliers.
