Studies about genetic divergence in 40 genotypes of Tomato (Solanum lycopersicum L.)

Present investigation was carried out at Vegetable Research Farm, Kalyanpur, Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during Rabi season of 2019 -2020. Forty genotypes were evaluated for 10 growth and yield traits which were grouped into five clusters. Cluster III and V had maximum (10) genotypes followed by cluster II (9), cluster I (7), cluster IV (4). Cluster I and cluster IV, exhibited high degree of genetic diversity due to maximum inter cluster distance between them. It indicating these genotypes may be utilized under inter varietal hybridization programme (transgressive breeding) for getting high yielding recombinants. Cluster IV has shown maximum mean days to flowering, plant height (cm), number of locule, fruit length (cm) Therefore, selection of parents from this cluster for these traits would be effective. Maximum contribution towards genetic divergence was obtained by number of fruits per plant (62.31 per cent) and plant heights (21.67 per cent).
