Abstract/ Executive Summary:

Performance of six different hybrid tomatoes (Lycopersicon esculentum) 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. A remarkable variation in plant characters and yield performance was noticed among the hybrids. The magnitudes of phenotypic coefficient 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.

Keywords: Hybrid tomatoes, Plant characters, Yield and yield performance

Location: Genetics and Plant Breeding research field, Hajee Mohammad Danesh Science and Technology University, Dinajpur

Start Date: 00-11-2011

End Date: 00-04-2012

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To find out the performance of different commercial tomato hybrids and to select the outstanding tomato hybrids.

Methodology:

The hybrids seedling were raised in nursery upto 30 days and transplanting in main field with spacing of 60 cm x 60 cm during Mid-October 2011 at the Genetics and Plant Breeding experimental field, HSTU, Dinajpur. The design followed was Randomized Block Design (RBD) with three replications. In each replication, each hybrid seedlings were planted in a plot size of 6m x 3m. All the recommended package of practices for tomato of this Zone was followed throughout crop duration according to requirements. Stalking and side branch pruning and frequent irrigations was done whenever necessary. Observations were recorded on ten randomly selected plants of each hybrid in each replication for ten characters viz., plant height, Canopy width, days to 50 per cent flowering,number of fruits per plant, Fruit length, fruit diameter, Single fruit weight, 100 seed weight, Shelf life and yield per plant. Statistical analysis was done for RBD design.

Achievement/Findings:

Yield of Mintoo super, Delta, BARI hybrid-4 is higher than the check varieties Ratan and Roma vf but only the hybrid Delta has higher shelf life with less variable fruit characters than two check varieties. It may be concluded that the tomato single cross hybrids Mintoo super and Delta are promising under Northern part of Bangladesh.
