Abstract:

A genetic analysis study was carried out for yield and its attributing characters in 7 × 7 half-diallel crosses of ridge gourd (Luffa acutangula Roxb.) the research farm of Division of Vegetable Science, Indian Agricultural Research Institute, New Delhi. The twenty one F1 hybrids along with seven parental lines were grown in randomized block design in three replications. Estimation of genetic components of variation and graphical presentation deduced that most of the traits under study showed over-dominance and low narrow-sense heritability indicating predominance of non-additive gene action for the inheritance. Dominance effect (H) was found to be higher than additive effect (D) and average degree of dominance was more than one for all the characters, thereby confirming the predominant role of non-additive gene action and commercial exploitation of heterosis for improvement of these traits. The graphical analysis further indicated the importance of over dominance and positions of parental arrays in the graphs were scattered suggesting parental diversity foe the various traits studied.
