Abstract:
The present investigation was carried out to determine the genetic diversity of 273 soybean germplasm. Cluster analysis was performed for quantitative traits in soybean. Based on cluster analysis, the genotypes were grouped into 7 clusters of which cluster IV is the largest clusters consisting of sixty-seven genotypes while cluster VI was the smallest with five genotypes. The maximum intra-cluster distance was obtained for cluster VI (5.415) consisting of 67 genotypes. The highest inter cluster distance values were observed between cluster VI and III (8.096). The minimum intra-cluster distance (2.491) was shown by cluster II. The intra cluster distance varied from 2.49 to 5.41. The highest inter cluster distance values were observed between cluster VI and III. The lowest inter-cluster D2 value was found between cluster IV and III (2.471). The inter cluster distance varied from 2.471 to 8.096. All the intercluster distances were larger than the intra-cluster distance indicating the presence of wider diversity among genotypes of distance groups. These studied which will allow breeders further improvement in the varieties for quantitative traits through hybridization.
