Abstract
The genetic parameters, character association and path coefficient analysis between yield and yield contributing characters of 25 lentil genotypes were studied during 2007 - 2008 at Kisan (PG) College, Simbhaoil. The genotypes exhibited a wide range of variability for all the traits studied. High heritability accompained by moderate to high GCV and genetic gain were observed for number of pods plant-1, number of branches plant-1, 100 seed weight, seed yield plant-1 and harvest index. Correlation studies indicated that number of pods plant-1, biological yield and harvest index were positively and significantly correlated with seed yield at both phenotypic and genotypic levels. Path coefficient analysis showed that harvest index, biological yield and number of pods plant-1 showed maximum and positive direct effect on seed yield.
Key words: Correlation, path coefficient analysis, genetic variability, lentil.
