Abstract

The genetic divergence of Tomato was studied with twenty three selected genotypes using D2 statistics and principal component analysis at Regional Agricultural Research Station, BARI, Akbarpur, Moulvibazar, Bangladesh during 2014 to 2015.The genotypes were grouped into 5 clusters and the maximum number of genotypes were included in cluster I and the minimum number in cluster V. The highest intra- cluster distance was observed for the cluster II and the lowest for the cluster V. For cluster III, the highest mean values for days for 50% flowering, individual fruit weight, fruit diameter, pericarp thickness, number of locules per fruit, yield per plant, yield ton per hectare were recorded. The first axis largely accounted for the variation among the tomato genotypes (50.88%) followed by second axis (20.33%). The first five axes accounted 91.71 % of the total variation. Considering the magnitude of cluster means for different traits and performance the genotypes of cluster III and V may be considered as parents for future hybridization program for improvement of tomato.
