Abstract: In the recent years, the research and promotion on maize breeding slowed down due to inadequate germplasm resources and lack of elite inbred lines. In order to solve genetic frangibility of domestic germplasm and make yield of hybrids breakthrough quickly, a large number of tropical and subtropical
