ABSTRACT
Studies were conducted on genetic diversity among selected local land race for economic traits in rice. Based on D2 values, 100 genotypes were grouped into 9 clusters. The intra cluster distance varied from 4.403 in cluster I to a maximum distance of 28.517 in cluster II. This reveals the presence of diverse genotypes within different clusters. The inter cluster D2 values also ranged widely with minimum value of 10.22 between cluster VI and cluster V and maximum value of 42.407 between cluster III and cluster VII indicating high diversity among the genotypes. Based on the overall score across 13 traits, the cluster VI first rank followed by cluster II and III indicating presence of most promising genotypes in them and can be extensively used for further breeding programme to generate new material.
