Evaluation and Selection of 36 M3 Tomato Mutants

Dr.Shamsed Begum
Chief Scientific Officer
Plant Breeding Division BINA BAU CampusMymensingh-2202.Bangladesh.

Abstract/ Executive Summary:

Plant height ranged from 69.5 cm to 96.0 cm. Days to first ripening varied from 75 to 92 days with a mean of 84.7 days. Number of fruits per plant and average fruit weight ranged from 15 to 36 number and 60 g to 80 g. In case of fruit yield/plant, it ranged from 1.3 to 2.3 kg with a mean of 1.85 kg, respectively. Of the all promising lines TM-130 was the shortest. In case of days to first ripening, The mutant TM-57-6-35 produced the highest fruit yield of 2.3 kg/plant followed by TM-53-4-35 (2.2 kg/plant).

Keywords: Tomato, Mutants, Yield, Evaluation.

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

Start Date: 01-06-2003

End Date: 30-06-2004

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To evaluate & select high yielding winter tomato (Lycopersicon esculentum Mill.) variety (s) with lower reaction to disease to major diseases and insect-pests.

Methodology:

Seeds of 36 mutants/varieties of tomato selected in the previous M₂ generation were grown in 5 m long plant progeny rows along with them mother at BINA farm, Mymensingh during October 2003 to February 2004. Out of these progenies 12 mutants were again selected on the basis of better plant type, higher number of fruits/plant with higher average fruit weight and higher fruit yield/plant. Data on different important plant characters were recorded from the selected mutants.
