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. It was observed from results that plant height ranged from 32.7 to 36.5 cm. The days to maturity ranged from 105 to 114 days for mutants while it was 114 days for mother variety of BARI masur-4. The mutant LM-37-8 matured earlier than the mutants and the check. The mutant LM-75-4 produced the highest number of pods per plant. In Magura, mutant LM-75-4 produced significantly the highest seed yield (2066 kg ha^-1) followed by LM-132-7, LM-37-8 and LM-185-2. At Ishurdi, mutants LM-75-4 produced the highest seed yield among the mutants and the check variety. The mutant LM-75-4 produced higher in average seed yield and number of pods/plant among the mutants and the check variety.

Keywords: Lentil, Mutants, Yield, On-stationl

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

Start Date: 03-11-2010

End Date: 23-03-2011

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 3 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.
