Abstract: Combining ability analysis in bottle gourd was studied through line (10) x tester (4) matting design over three environments (sowing dates) for fruit yield per vine and its component traits. The analysis of variance indicated significance of both additive and non-additive type of gene action in the expression of fruit yield per vine and its related traits. However, non-additive gene action played predominant role in expressing of all traits except for fruit length whereas other traits an additive gene action was more important. The parents ABGS 11-23, JBGL 42, JBGL 43, NDBG 104,NDBG 132, NDBG 604, ABG 1 and Pusa Naveen, showing significant gca effect in desired direction for fruit yield per vine and some fruit yield contributing traits. The best five crosses viz., JBOGL 01-59 x LCL 1, ABGS 11-17 x PSPL, ABGS 11-17 x ABG 1, DVBG 94 x LCL 1 and JBGL 43 x Pusa Naveen were good sca effect in desired direction for fruit yield per vine which involved either average or good general combiner parents, indicating the importance of non-additive gene action for fruit yield per vine and the potential of heterosis breeding for improving the productivity of bottle gourd.
