摘要:

亚洲栽培稻在驯化过程中形成了籼稻和粳稻2个亚种,两者在种植环境、植株和籽粒特性以及基因组等方面存在显著差异。有效利用籼粳亚种间的遗传差异,能够借助强大的杂种优势进一步提高水稻的产量。本文概述了籼稻和粳稻之间的分类与分化差异,论述了目前已经定位及克隆的亚种间杂种不育基因和分子作用机制,分析了已经鉴定的杂种优势基因及杂种优势作用机制,汇总了通过省级以上审定的籼粳杂交稻品种数据,旨在为水稻亚种间杂种优势利用的研究以及籼粳杂交稻新品种的培育提供有益思路。

关键词: 籼粳分化, 杂种不育, 杂种优势

Abstract:

Asian cultivated rice (Oryza sativa L.) has differentiated into two subspecies, indica and japonica, during domestication, exhibiting significant variations in cultivation environments, plant and grain characteristics, and genome. The effective utilization of genetic divergence between indica and japonica subspecies could further enhance rice yield through their strong heterosis. This paper systematically reviews the taxonomic classification and differentiation characteristics between indica and japonica, discusses currently mapped and cloned intersubspecific hybrid sterility genes and their molecular mechanisms, analyzes identified heterosis-related genes and their functional mechanisms, and compiles data of certified indica-japonica hybrid rice varieties approved at provincial or national levels. These comprehensive analyses aim to provide valuable insights for advancing research on intersubspecific heterosis utilization and developing novel indica-japonica hybrid rice cultivars.

Key words: indica and japonica differentiation, hybrid infertility, heterosis
