Abstract
The results showed that the inbred lines which have higher GCA effect should be used as the parents of the combinations,GCA and SCA together must be given attention too,so that the combinations of strong heterosis were crossed.The combinations 172×137 was better than others,and must be tested for their yield potentiality and adaptation at many locations in many years.The maize inbred lines such as 172,K12,173,137,were ideal.
