Genetic analysis for water use efficiency traits, yield and yield attributes in groundnut (Arachis hypogaea L.)
Keywords: Groundnut, Water use efficiency, Heritability, Genetic advance.
AbstractJL-220 recorded the highest per se performance for number of well-filled and mature pods per plant, 100-kernel weight, harvest index and protein per cent. ICGV-99029 recorded the maximum per se performance for number of secondary branches per plant, stomatal conductance, kernel yield per plant and pod yield per plant Number of secondary branches per plant had high heritability coupled with high genetic advance as per cent of mean is controlled by additive gene effects and is least influenced by environment and therefore selection would be very effective. Moderate heritability and high genetic advance as per cent of mean were observed for specific leaf weight, number of well-filled and mature pods per plant and dry haulms yield per plant indicating importance of both additive and non-additive gene action in the inheritance of these traits.
