STUDIES ON GENETIC VARIABILITY AND COMPONENT ANALYSIS IN MACROSPERMA AND MICROSPERMA LENTILS

Abstract

Studies on genetic variability and component analysis was under taken in lentil collection comprising 42 macrospenna and 40 micTosperma genotypes. The parallelism in the magnitude of PCY, GCY, heritability and genetic advance for all the traits in both types of lentils revealed considerable similarity in genetic variability possessed by these two varietal groups. The magnitude of heritability in conjunction with genetic advance in both types of lentils revealed additive genetic control for days to flowering, dominance or epistatic effects for days to maturity, and nonadditive gene action for the remaining characters. The path analysis indicated the importance of pods/plant or seeds/plant as the most important parameter contributing to seed yield/plant in macTosperma and micTospenna lentils.
