Abstract:
Combining ability effects were estimated for different traits in a line x tester crossing programme comprising 32 crosses produced by crossing 8 lines and 4 testers. The GCA and SCA mean squares were significant for all the traits under study except number of nodes per plant. The ratio of GCA and SCA variances indicated the preponderance of non-additive gene effect for inheritance of all the traits. Genotypes JOL-09-05, JOL-09-07, Pusa Swani and AOL-09-02 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 JOL-0-05 x AOL-09.02, JOL-09-07 x JOL-2K-19 and JF-55 x AOL-08-05 were observed most promising for fruit yield and some related traits.
