Zonal Yield Trial of Four Selected Mutants of Lentil

Dr. M. A. Samad
Chief Scientific Officer
Plant Breeding Division, Bangladesh Institute Of Nuclear Agriculture, BAU Campus, Mymensingh-2202

Abstract/ Executive Summary:

The results showed that significant variations were present in all the characters except number of primary branches/plant. It was observed from the results that plant height ranged from 36.4 to 40.8 cm. The days to maturity ranged from 99 to 113 days for mutants while it was 113 days for mother variety of BARI Masur-5. The mutant LM-156-1 matured earlier than both the mutants and the check variety. The mutant, LM-156-1, LM-6-7(2) and LM-123-7 produced higher number of pods per plant. In Magura, Lm-132-7 produced significantly the highest seed yield of 2576 kg/ha followed by LM-156-1 and LM-6-7(2). At Ishurdi, mutants LM-123-7 produced the highest seed yield among the mutants and check. On an average, mutant LM-123-7 also produced higher seed yield and number of pods plant^-1 than other mutants and check. The selected mutant lines LM-123-7, LM-156-1 and LM-6-7(2) will be grown in the next year to assess their yield potential at different locations of Bangladesh.

Keywords: Lentil, Mutants, Yield, Zonal yield trial

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

End Date:

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:

Five mutants along with 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 × 4 m. During final land preparation 80, 60 and 40 kg/ha were applied for TSP, MP and urea, respectively. Distance between rows and plants were 30 cm and 5-6 cm, respectively. During final land preparation Recommended cultural practices were followed. At harvest, 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. The collected data were analyzed statistically.
