Diallel mating design experiment with reciprocal crosses was used to determine combining ability of five maize inbred lines and their hybrid combinations for grain yield, ear length, ear diameter, number of kernel rows per ear, number of kernels per row in 2005 and 2006. GCA/SCA relation showed that dominant gene effect had prevalent influence in the inheritance of grain yield, ear length and ear diameter. Additive gene effect had larger importance in the inheritance of number of kernel rows per ear. NS-1445 inbred line showed best GCA for grain yield, ear length and number of kernels per row, but worst GCA for number of kernel rows per ear. Best GCA for ear diameter achieved inbred line F-7R. Line BL-47 showed best GCA for number of kernel rows per ear in both years, but also the worst GCA for grain yield and number of kernels per row. Hybrid combination NS-1445 x BL-47 showed largest SCA for grain yield in both years and also showed, like hybrid combination F-7R x NS-1445, significant SCA for all other traits except ear diameter. Reciprocity effect was significant for SCA effects for all traits but ear diameter. It is the conformation of involvement of plasmagenes in maize quantitative traits inheritance. Largest reciprocity effect for grain yield achieved F-7R x BL-47 in both years.
