Preliminary Yield Trial of Some Promising Mutants of Lentil

Dr. M. A. Samad
Principal Scientific Officer
Plant Breeding Division, BINA, BAU Campus, Mymensingh-2202

Abstract/ Executive Summary:

Results showed significant variations in all the characters. The days to maturity ranged from 106 to 114 days for mutants while it was 114 days for mother variety of BARImasur-4. The mutant LM-75-4, LM-24-3 and LM-21-6 produced higher number of pods per plant. At Ishurdi, mutants LM-75-4 produced significantly the highest seed yield (1611 kg/ha) followed by LM-24-3 and LM-21-6. The mutants LM-75-4 and LM-24-3 produced significantly the highest seed yield at Magura. But in average, the mutant LM-75-4 produced significantly the highest seed yield.

Keywords: Lentil, Mutants, Yield, Preliminary yield trial

Location: Experimental field at BINA sub-station Ishurdi and Magura

Start Date: 07-11-2007

End Date: 31-03-2008

Program Area: Variety and Species

Commodity: Lentil

Objectives:

Development of varieties with bolder seed, earliness, higher seed yield with improved nutritional quality and resistance/tolerance to rust, root rot and blight

Methodology:

Ten M6 mutants along with the check variety, BARImasur-4 were put into preliminary yield trial at Ishurdi and Magura. The experiment was carried out in a randomized complete block design with three replications. Unit plot was 4 m x 1.5 m. Distances between rows and plants were 30 cm and 5-6 cm, respectively. Plant height, number of primary branches/plant, days to maturity, number of pods/plant and seed yield (kg/ha) were recorded from randomly selected 10 plants of each plot.

Achievement/Findings:

Out of ten mutants, two mutants (LM-75-4 and LM-24-3) showed promising in respect of number of pods/plant and seed yield. The selected mutant lines will be grown in the next year to assess their yield potential at different locations of Bangladesh.
