Preliminary Yield Trial of Promising Mutants of Tomato

Dr.Shamsed Begum
Chief Scientific Officer
Plant Breeding Division, BINA, Mymensingh

Abstract/ Executive Summary:

The mean results showed that TM-105 was the shortest (46.0 cm) among all entries. In case of fruit ripening TM-105 took the lowest days to fruit ripening (88 days) followed by TM-165 (90 days). Of the all promising lines TM-153 produced the highest average fruit weight of 74 g followed by TM-52 (68g) and TM-163 (65g). In case of fruit yield five mutants showed higher fruit yield than the check varieties. TM-144 produced the highest fruit yield of 87 t/ha followed by TM-153 (80 t/ha).

Keywords: Tomato, Mutants, Yield, Preliminary trial.

Location: Experimental farms BINA sub-stations at Magura, Ishurdi and Rangpur.

Start Date: 01-06-2004

End Date: 30-06-2005

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To evaluate and to select desirable mutants from a large plant population high nutritive value.

Methodology:

Ten mutants along with two check varieties were put into advanced yield trials at 3 locations during winter of 2004 to February 2005. The experimental design was RCBD with 3 replications. Unit plot size was 5 m x 4 m having spacing of 50 cm between both rows and plants. Recommended cultural practices were followed as and when necessitate. Data on (yield and yield contributing characters) 90% fruit ripening, number of fruits/plant, average fruit weight and fruit yield per plant were recorded. Plot fruit yield was converted into ton per hectare. All the collected data were subjected to appropriate statistical analyses.
