作物超高产育种途径探析

摘要

本文以3大粮食作物水稻、小麦和玉米为例,阐述了作物超高产育种的概念,归纳了作物产量形成的生理基础,并从理想株形选育、高光效育种、遗传资源的发现与创新和生物技术手段4个方面分析了作物超高产的途径.%In this paper, the three major food crops of rice, wheat and corn as an example, the concept on super high-yielding breeding and the yield physiological basis of crop are summed up. The ways for super high-yielding breeding of crop are analyzed from four aspects of ideal plant type breeding, high photosynthetic efficiency breeding, discovery and innovation of crop genetic resources and biotechnology means.
