Estimation of path analysis of mutant lines of lentil (Lens culinaris Medik L.)

Abstract

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 genotypic path analysis, the secondary branches showed the highest positive direct effect (0.991) on grain yield followed by test weight (0.8706) and number of pods per plant (0.2640) in year 2017-18. In phenotypic path analysis, the number of pods per plant showed highest positive direct effect (1.054) followed by days to 50% flowering and test weight (0.0436) in year 2017-18. So that maximum importance of these characters might be given in selection program me.
