【摘要】 目前籼粳亚种间杂交稻绝大多数为粳不籼恢亚种间杂交稻。自第1个粳不籼恢亚种间杂交稻甬优6号在浙江省通过品种审定以来，利用粳型不育系与籼粳中间型广亲和恢复系配组，已选育出了一批有影响力的籼粳杂交稻，表现出超高产的产量潜力，在生产上广受欢迎。本文对我国籼粳亚种间杂交稻的发展历史、粳不籼恢亚种间杂种优势利用研究的现状进行回顾与展望，以期为我国今后籼粳亚种间杂种优势利用研究和籼粳亚种间杂交稻培育提供有益的借鉴与参考。更多还原

【Abstract】 The main type of indica-japonica hybrid rice was bred by the japonica CMS line as female parent and the wide-compatibility indica restore line as male parent. The first typical japonica-indica hybrid rice Yongyou 6 was bred by crossing japonica CMS Yongjing 2A and indica restore K4806 in Zhejiang province. In recent year, a number of influential japonica-indica hybrid rice were bred by the similar breeding mode with obvious yield advantages and were welcomed by farmers. This article reviewed the history of indica-japonica rice research, focusing on the present situation of utilization of heterosis between japonica CMS lines and the widecompatibility indica restore lines, in order to provide a useful reference for the future research on the utilization of heterosis between indica and japonica rice subspecies.更多还原
