摘要
黄淮海夏玉米产区占全国玉米种植面积的30%以上,生产上用的主栽品种较少,种质基础狭窄,抗风险能力较弱。解决的关键是在加强育种技术创新和种质创新的基础上,不断培育出能够支撑玉米生产可持续发展的新自交系和杂交种。
The maize planting acreage in Huanghe-Huaihe river summer maize area was over 30% in China. There were few central hybrids in production, the germplasm base was straitness and the ability resisting venture was very infirm. To resolve this problem, it was the sticking point that the breeding technique innovation and the germplasm innovation should be reinforced. Then the new maize lines and hybrids could be inaugurated to support maize production sustained development.
