Abstract:
The objective of the present study was to estimate the genetic parameters and hybrid vigor of yield and yield contributing traits in lentil through additive-dominance model. Mean found to be significant in all cases which indicating polygenic nature of the traits. Parameters [d] and [h] significant in few cases indicating that both additive and dominant gene effects played an important role in the inheritance of the respective traits. In all crosses and for all characters, mid-parent and high-parent heterosis were not significant except the cross P۵ × P۶. Potence was non-significant in most cases which indicated that differences don’t exist between F۱ and F۲ generations. It was revealed from the joint scaling test that for most characters in different crosses χ۲ values were not significant. Non-significant χ۲ test indicated the adequacy of additive-dominance model and hence those traits carry only additive and dominant genes which can be used in breeding programs to improve lentil varieties.
