PERFORMANCE OF DIFFERENT HYBRID VARIETIES OF TOMATO (Lycopersicon esculentum L)

Abstract

Performance of six different hybrid tomatoes (Lycopersicon esulentum ) namely BARI hybrid-4, Mintoo super, Delta, Mintoo, Unnayan and Tripti-2 with two check variety Ratan and Roma Vf (Popularly grown at chirirbandar, Dinajpur) were conducted in the Genetics and Plant Breeding research field, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during November 2011 to April 2012. Ten characters were studied namely days to 50% flowering, plant height, fruit diameter, fruit length, individual fruit weight, canopy width, marketable fruits/plant, shelf life, thousand (1000) seed weight, yield/plant. A remarkable variation in plant characters and yield performance was noticed among the hybrids. The magnitudes of phenotypic co-efficient of variation were higher than corresponding genetic co-efficient of variation. Mintoo super was the highest yielding hybrid possessed highest individual fruit weight and plant height and second highest fruit diameter. The second highest yielding hybrid Delta possessed second highest fruit weight and plant height. It also produced moderate shelf life but longest days required for 50% flowering. The third highest yielding hybrid was BARI hybrid-4, which had highest number of marketable fruits per plant and better fruit weight, which contributed mainly to yield, compared to other hybrids and the check varieties. Yield of Mintoo super, Delta, BARI hybrid-4 is higher than the check varieties Ratan and Roma vf but only the hybrid variety Delta has higher shelf life with less variable fruit characters than two check varieties.
