ASSESSMENT OF GENETIC VARIABILITY, CORRELATION AND PATH COEFFICIENTS FOR YIELD COMPONENTS AND QUALITY TRAITS IN TOMATO
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 54
Abstract
The present study was carried out during the Autumn- winter period of 2014-2015 at Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya, Nadia-West Bengal, with eighteen tomato genotypes including seven cultivars of Solanum lycopersicum viz., Berika, AC Aft, BCT-48, BCT-59, BCT-82, BCT 115dg, Pathurkuchi, five wild species namely Solanum pimpinellifolium, Solanum chilense (EC 513698), Solanum cheesmaniae, Solanum lycopersicum var. cerasiformae (EC 514013), Solanum peruvianum (EC251790), three inter specific hybrids (ISH) viz., ISH1- AC Aft x EC 514013, ISH2-Berika x EC 514013, ISH3-BCT 115dg x EC 514013 and three back cross progenies viz., ISH 1 XAC Aft, ISH2 X Berika, ISH 3 X BCT 115 dg. The characters that exhibited higher GCV and PCV values were for fruits per plant (119.35), polar diameter, fruit weight, number of cluster per plant, number of seed per fruit, test weight, plant height, number of primary branches per plant, number of fruits per cluster, locule number, flowers per cluster, equatorial diameter. High heritability along with high genetic advance as per cent of mean was observed for the traits like fruits per plant, number of cluster per plant, fruit weight, number of seed per fruit, test weight. The association studies indicated that fruit yield had significant positive correlation with fruits per cluster and fruits per plant.
