| Abstract | ||
| The objective of this experiment estimation general, specific combining ability and gene action for maize inbred lines. Field experiments were conducted in spring and fall seasons during 2012 and 2013. Ten inbred lines of maize (BK164, BK147, BK129, BK128, BK127, BK121, BK115, BK110, BK105, BK104) were included in this study. The inbred lines were diallel crossed to produce single croses and reciprocal hybrids, using Griffing method one. Varietal trail was conducted for parents and crosses using RCBD with three replicates in order to parameters. The results were showed in three seasons, significant differences among inbred lines in GCA and crosses among SCA in all characters. The parents BK104, BK129, BK115, BK164 and BK128 showed best combination effect. The average degree of dominance more than one in all the seasons. All the traits under Additive gene action. | ||
