摘要
水稻是我国最主要的粮食作物之一,20世纪50年代矮源基因在育种中的应用和70年代杂种优势的利用使水稻产量实现了两次飞跃。近年来,虽然水稻产量徘徊不前,但基于理想株型的综合设计让水稻产量的新突破成为可能。本文从水稻根、茎、叶、穗、分蘖等几部分的遗传进展综述了水稻理想株型的设计塑造。
Rice is a staple food crop in China. With the wide adoption of semi-dwarf varieties since 1950s and the developing of hybrid rice since 1970s, the yield of rice achieved two leaps. In recent years, rice yield was stagnating: But with the comprehensive design of ideal plant type, making a new breakthrough is possible. The authors briefly reviewed the genetic progress on rice ideal plant type in roots, stems, leaves, spikes and tillers.
