Advanced Yield Trial for the 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 105 to 116 days for mutants while it was 116 days for mother variety BARI masur-4. The mutant LM-20-3 matured earlier than the check variety BARI masur-4. The mutants LM-101-8, LM-48-1 and LM-14-2 produced higher number of pods per plant than the mutants and check. At Magura, mutant LM-101-8 produced significantly the highest seed yield of 1995 kg ha^-1 followed by LM-48-1 among the mutants and the check variety. The mutant LM-101-8 produced the highest seed yield at all the locations. But, in average the mutants LM-101-8 produced significantly the highest seed yield of 1936 kg ha^-1. Out of 8 mutants, three showed promising in respect of number of pods/plant and seed yield.

Keywords: Lentil, Mutants, Yield, Advancd yield trial

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

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:

Eight mutants along with the check variety, BARI masur-4 were put into an advanced yield trial at Magura, Ishurdi and Jamalpur. The experiment was carried out in a randomized complete block design with three replications. Unit plot was 4 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 seed yield (kg ha^-1) 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.
