Title: Review on Maize Heterosis Utilization of China and Prospect of Improved Hereditary Traits for Future Breeding
Abstract: The paper reviewed the course of the enlighten and initiate stage(1926-1948) for the investigation of heterosis utilization in maize(Zea mays L.),and the development course of crosses between cultivar,double,three-way and single cross after the found of the People's Republic of China since 1949.The paper point out the distinguishing feature and obvious advantages of the development for hybrid maize investigation in our country.The success of some main force inbred lines that bred by integrated method and technology during this time will draw great inspiration effects from their experiences to future breeding.The improved hereditary traits,breeding objectives,breeding ideas for future breeding and the question of heterosis definition were discussed and prospected.It is demended in future breeding that raising the density-tolerant cultivar,single-plant heterosis under less density,no stress and resistance to bioltic and abioltic adverse circumstances in a mode rate degree,and some physiological characters of photosynthesis function etc.
