Abstract:
The genetic divergence among 28 genotypes of sweet potato [Ipomea batatas (L.)] was determined through Cluster analysis and Mohalanobis’s D2 analysis. The cluster analysis grouped all 28 sweet potato genotypes into 8 major clusters based on D2 value. Extreme genetic divergence was estimated among clusters. Maximum number of genotypes were grouped into cluster I included 10 genotypes. Which would be fruitful for developing heterotic cross combination. The maximum intra-cluster distance was shown by cluster I (149.06) followed by cluster II (128.68) indicating maximum diversity within these clusters. Cluster V showed highest mean value for no. of tubers per plant (4.29), which was followed by cluster III (4.25), cluster VII (3.57), cluster VI (3.52) and cluster I (3.37). Tuber weight per plant showed maximum cluster mean performance in cluster VI (381.26 g), which was followed by cluster V (378.96 g), cluster III (360.28 g), cluster VI (293.80 g) and cluster I (258.959 g).
