On-farm Yield Trial of Two Mutants and a Check Variety of Lentil

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

Abstract/ Executive Summary:

The duration and yield of lentil mutants/variety ranged from 97-110 days and 2494-1996 kg ha^-1, respectively at Magura of which the mutant LM-75-4 produced highest yield (2494 kg ha^-1) than the remaining mutant and check variety. The mutant LM-75-4 matured earlier by 9-12 days than the check variety, while at Jessore the mutant LM-75-4 produced highest yield (2385 kg ha^-1) followed by the mutant LM-132-7. At Natore and Ishurdi, mutants LM-75-4 and LM-132-7 produced higher seed yield than the check variety. The duration of LM-75-4 ranged from 97-105 days and that of LM-132-7 and BARI masur-4, 98-106 days and 110-115 days over the locations with mean 101 days, 103 day and 113 days, respectively. Yield ranged from 2170-2494 kg ha^-1, 2120-2307 kg ha^-1, and 1756-1996 kg ha^-1, respectively in the mutants LM-75-4, LM-132-7 and BARI masur-4 with mean yield over all locations 2289, 2197 and 1868 kg ha^-1.

Keywords: Lentil, Mutants, Yield, Farmers field

Location: Farmers field at Ishurdi, Natore,Rajshahi, Jessore and Magura

Start Date: 00-00-2012

End Date: 00-00-2013

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:

Trials on two promising lentil mutants along with a check variety were conducted at Natore, Ishurdi, Rajshsahi, Magura and Jessore during 2012-13 in order to assess the performance of those mutants at farmer’s field. The mutants were LM-75-4, LM-132-7 and BARI masur-4 (check). Each trial was conducted in non-replicated field of 10 m X 10 m. Seeds were sown @ 35 kg ha^-1 in lines with 30 cm distance between rows. Data on days to maturity and yield kg ha^-1 were recorded from each trial and summarized.
