摘要
作者通过十几年的小麦高产育种实践和理论分析,认为大穗型育种是冬小麦超高产育种的有效途径。在一定植株高度的基础上,适当降低单株有效穗数,提高单株每穗粒重是实现小麦超高产的突破口。以半矮秆、多抗性、穗大、粒重获得小麦的超高产量。
With more than 10 years practice of winter wheat high-yield breeding, the author realized breeding larger-ear varieties being an efficent way. Proper decrease of effective ears per plant and increase of grain weight per ear with semi-dwarf stalks, polyresistances,larger ears and heavy grains were the key to realize super-high-yield of winter wheat.
