| Abstract: | Six genotypes of Cuphea Procumbens, rich in capric acid (C10:0) were hybridized in half diallel fashion to study the combining ability and heterosis for plant spread] primary branches and secondary branches/plant Gca and sca variances were significant for all the characters though high gca variance for primary branches and secondary branches/plant indicated the prevalance of additive gene action while high sca variance indicated the dominance gene action for plant spread. Parent NBC-30 was found significantly superior combiner for all the characters. The crosses NBC-25 × NBC-30 and NBC-01 × NBC-25 showed significant specific combining ability for all the 3 characters, while hybrid NBC-25× NBC-30 exhibited significant sca effed for plant spread and secondary branches/plant, The heterosis over better parent was noticed upto 36.8 persent for plant spread, 20.8 percent for primang branches 20.46 percent for secondary branches/plant. in general hybrids showing high heterosis had also high per-se performance. |
