Character association, Environments, Lentil, Path coefficient analysisAbstract
Fifty diverse genotypes of lentil were evaluated for character association and path coefficient analyses under two environments created by the use of single and double dose of N, P and K. Seed yield/plant showed significantly positive association with biological yield/ plant and harvest index in both the environments, with pods/plant in E,and primary branches/plant in E, Path analysis indicated that biological yield/plant had the maximum positive direct effect on seed yield in both the environments, followed by pods/plant and seeds/pad. Almost all the yield contributing characters had higher positive indirect effects via biological yield/plant.
