Combining ability studies in okra (abelmoschus esculentus (l.) moench) for yield and its component characters

Abstract

The present experiment was conducted with 28 F1s developed through diallel hybridization technique excluding reciprocals along with eight parents in RBD with three replications. The gca and sca mean squares were significant for all the traits except gca mean square for fruit length. The ratio of gca and sca variances indicated the preponderance of non-additive gene effect for inheritance of all the traits. Genotypes AOL-09-25 and GO-2 showed good general combining ability for fruit yield appear to be worthy for exploitation of segregation and varietal development. The estimates of sca effects revealed that the cross combinations AOL-09-25 x AOL-09-26, GO-2 x AOL-09-28 and AOL-08-10 x AOL-08-2 were observed most promising for fruit yield and some of its related traits.
