Abstract
from International Centre for Agricultural Research in the Dry Areas (ICARDA) including some advanced lines from Bangladesh Institute of Nuclear Agriculture in 2006. During Preliminary Yield Trial, the genotype LG-208 produced 18.62% and 29.47% higher seed yield than the check variety BARI Masur-5 at Ishurdi and Magura respectively. Through advanced yield trials, regional yield trials, on-station and on-farm trials from 2010-11 to 2015-16, it was found that exotic germplasm LG-208 showed better performance than check (BARI Masur-5). Genotype LG-208 had significantly highest seed setting and harvest index under 20% polyethylene glycol (PEG) induced drought and considered as the drought tolerant which showed similar performance with field trials in drought-prone areas (Chapainawabganj and Rajshahi). Based on the superior performance of exotic germplasm LG-208 line, BINA has decided with the National Seed Board (NSB) of Bangladesh to register this line as a high yielding drought tolerant lentil variety, named as Binamasur-10 in 2016.

Highlights
Lentil (Lens culinaris Medik) 2n =14, of the family Leguminosae, is one of the ancient food crops originated in the Fertile Crescent of the Middle East (Renfrew, 1969)
Crop plants can be improved by natural or induced genetic variations through mutation, gene recombinant and germplasm collection (Ghafoor et al, 1989).Through the preliminary yield trial during Robi 2008-2009, 13 accessions were selected comparing with the check variety BARI Masur-5 following randomized complete block design with three replications at Ishurdi (Table 1) and Magura (Table 2)
The results revealed that drought stress decreased traits of seed yield and harvest index and it was clear that reaction of characters due to drought stress was different
Summary
Lentil (Lens culinaris Medik) 2n =14, of the family Leguminosae, is one of the ancient food crops originated in the Fertile Crescent of the Middle East (Renfrew, 1969). It was first domesticated in Southern Turkey; from there it moved to Europe and Asia (Ladizinsky, 1979; Cubero, 1984). Drought stress is responsible for reductions in plant growth, root functioning, leaf area development, cell membrane stability, alterations in biomass and nitrogen allocation in different plant parts (Hamidi and Erskine, 1996; Kurdali et al, 1997; Sio-SeMardeh et al, 2006; Shrestha et al, 2006; Gunes et al, 2008; Singh et al, 2013; Mishra et al, 2014)
