Abstract
Fifty-three traditional rice genotypes (Oryza sativa L.) were characterized by following the 41 DUS descriptors, which includes 29 qualitative and 12 quantitative traits. The data used for qualitative and quantitative cluster analysis. In qualitative and quantitative cluster analysis, the genotypes grouped into six clusters. Both qualitative and quantitative clustering analyses revealed distinct patterns of genetic diversity among the traditional rice genotypes. The genotype, G31 grouped in cluster VI in both cluster analyses. In quantitative cluster analysis, cluster III possessed genotypes with relatively larger leaves, thicker stems and larger panicles. Cluster VI displayed highest panicle number per plant, longest grain length and lowest mean days for time maturity. Genotypes in these clusters could be explored further for their potential in enhancing yield and quality characteristics.
