On Station Yield Trial of Four Selected Mutants of Lentil

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

Abstract/ Executive Summary:

Results showed that significant variations were present in all the characters except number of primary branches/plant. The days to maturity ranged from 103 to 112 days for mutants while it was 112 days for mother variety of BARI masur-4. The mutant LM-156-1 matured earlier among the mutants and the check. The mutant LM-123-7 produced the highest number of pods per plant. In Magura, mutant LM-123-7 produced significantly the highest seed yield (2061 kgha-1) followed by LM-28-2 and LM-156-1. At Ishurdi, mutants LM-123-7 produced the highest seed yield among the mutants and the check variety. But, the mutant LM-123-7 produced higher in average seed yield and number of pods/plant among the mutants and the check variety. The selected mutant lines LM-123-7 and LM-28-2 will be grown in the next year to assess their yield potential at different locations of Bangladesh.

Keywords: Lentil, Mutants, Yield, Farmers field

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

Start Date: 05-11-2011

End Date: 28-03-2012

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:

Four mutants along with a check variety, BARI masur-4 were put into on station yield trial at Maugra and Ishurdi. The experiment was carried out in a randomized complete block design with three replications. Unit plot was 5 m x 4 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 yield per plot were recorded from randomly selected 10 plants of each plot. Plot yield was converted to kg ha^-1. Statistical analysis of different characters of the mutants and check variety.
