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。

Abstract: 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.

Key words: rice, ideal plant type, genetic basis
