Advanced Yield Trial for the Selected Mutants of Lentil

Dr. M. A. Samad
Chief Scientific Officer
Plant Breeding Division, Bangladesh Institute Nuclear Agriculture, BAU Campus, Mymensiungh-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 results that plant height ranged from 37.4 to 41.0 cm. The days to maturity ranged from 99 to 113 days for mutants while it was 113 days for mother variety BARI Masur-5. The mutant LM-48--1 matured earlier than the check variety BARI Masur-5. The mutants LM-48-1 and LM-24-3 produced higher number of pods per plant than the mutants and check. At Magura, mutant LM-48-1 produced significantly the highest seed yield of 2296 kg/ha followed by LM-24-3 among the mutants and the check variety. At Ishurdi, the mutant LM-48-1 produced the highest seed yield at all the locations. On an average, the mutants LM-48-1 also produced the highest seed yield of 2250 kg ha^-1. Out of seven mutants, two showed promising in respect of number of pods plant^-1 and seed yield. The selected mutant lines of LM-48-1 and LM-24-3 will be grown in the next year to assess their yield potential at different locations of Bangladesh.

Keywords: Lentil, Mutants, Yield, Advanced, Yield trial

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

Start Date: 07-11-2013

End Date: 31-03-2014

Program Area: Variety and Species

Commodity: Lentil

Objectives:

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

Methodology:

Seven mutants along with the check variety, BARI Masur-5 were put into an advanced yield trial at Magura and Ishurdi. The experiment was carried out in a randomized complete block design with three replications. Unit plot was 4 m × 3 m. Distances between rows and plants were 30 cm and 5-6 cm, respectively. Plant height, number of primary branches plant^-1, days to maturity, number of pods plant^-1 and seed yield (kg ha^-1) were recorded from randomly selected 10 plants of each plot. Plot yield was converted to kg ha^-1. Recorded data were subjected to proper statistical analyses.
