Abstract
Blight is an important disease that cause devastating yield loss now a days. That’s why, an investigation was carried out at the Regional Agricultural Research Station (RARS), Bangladesh Agriculture Research Institute (BARI), Barishal for screening of lentil germplasms against stemphylium blight in terms of yield and yield attributes. To find the best genotype, 40 moderately stemphylium resistant lentil lines/ genotypes were used and their different yield contributing characters were analysed. In this study, it has been observed that the long delay of 1st flowering was recorded in BD-5982 and BD-5996 while early flowering in BD-3927 and BARI masur-7. The highest 50% flowering days was recorded in BD-3983, BD-4024, BD-4053 etc. and lowest in BD-3922. Long maturation period of 111.5 days was recorded in BD-4024 and that of short maturity date was recorded in BD-3924 and BD-3927. The highest plant height was observed in BD-3974 and lowest was in BD-4127. The maximum number of branches per plant was observed in BD-3936 and BD-4024 and minimum was found in BD-4097. Maximum number of pods per plant was recorded in BD-3922 and minimum number of pods per plant was in BD-4053. The lowest number of seeds per pod was recorded in BD-4053. The highest 100 seed weight was recorded in BD-5986 and the lowest was observed in BD-4127. Maximum biological yield was recorded in BD-4053 and minimum was in BD-5989. The highest and lowest grain yield was recorded in BD-5983 and BD-4024, respectively. This finding will help researcher to develop new variety in near future.

Summary
Major food crops that exists in the Southeast Asia, pulses assume a vital role in improving the diet of the people because of its high nutritional esteem. It is an imperative food for immense individuals in developing countries, where it is a basic source of proteins and contains the amino acid lysine, which is for the most part insufficient in food grains (Iqbal et al, 2006). Several causes are responsible for low yield of lentil of which the use of traditional local cultivars, unfavorable weather conditions (Vanderberg, 2007), different biotic and abiotic stresses (Schneider and Anderson, 2010), low plant density unit-1 area, weed infestation and poor crop management practices constitute the major ones (Yadav et al, 2017). In Bangladesh frequently rabi rainfall is insufficient for successful the production of lentil, because water deficit in lentil fail to develop properly on account of retardation in photosynthetic and metabolic activities resulting in decreased number of pods plant-1, seeds pod-1 and 1000-seed weight
