Abstract: Lentil is also used as nitrogen fixing crop. According to FAO statistical report, 2014 world lentil production 2012 in totaled to 4,557,972 tonnes from 4,206,024 ha area harvested. India alone produces 20.84% of world production. Lentil is self-pollinated crop (2n=14) and large genome size 41063Mbp. Seed of 9 induced mutant lines of lentil (Lens culinaris Medik. L.) were used for the experimental purpose. These mutants were isolated from variety K-75 with gamma ray and EMS treatment. The self-seeds of all mutants were sown in randomized block designed in three replications at Agricultural Research Farm, Institute of Agricultural sciences, B.H.U, Varanasi, during Rabi 2017-18.Distance between row to row and plant to plant was maintained 30cm and 5cm respectively. In phenotypic correlation, number of pods per plant (0.8504), number of secondary branches per plant (0.6395) showed positive and highly significant correlation with grain yield per plant. Number of pods per plant exhibited positive and highly significant correlation with number of secondary branches per plant (0.7758). In genotypic correlation, positive and significant correlation were exhibited by number of pods per plant with number of secondary branches, grain yield with number of secondary branches, grain yield with number of pods per plant, days to maturity with 100% flowering and days to 50% flowering with grain yield. So that from above interrelationship could be cleared that improving yield in lentil and ideal plant type would be expected to have more number of pods per plant and number of secondary branches per plant. In selection program me, inter-relationship of a number of characters with grain yield and among themselves studied.
