当前大面积推广的杂交水稻不能自己留种,第二年都得重新买新种子。而且制种成本是常规稻种的10倍以上。2017年,中国水稻研究所王克剑研究员团队成功研发出首批杂交稻克隆种子。经过数年攻关,团队成功培育出一系法杂交水稻“一系1号”,克隆效率稳定超过99%,而且结实正常。该成果7月21日刊发于国际期刊《Vita》(《生命》)。以前是每年杂交、每年制种,现在有望实现“一次杂交、代代可用”。<br> (科技日报 潘宇菲 马爱平 赵卫华)5517412026-07-22 19:57:40:572潘宇菲 马爱平 赵卫华一系法杂交水稻取得关键突破 克隆效率稳定超过99% 有望实现一次杂交、代代可用1324滚动滚动<br> https://www.stdaily.com/web/gdxw/pic/2026-07/22/551741_t1_1X0X600X337_c0aa8a04-64a0-4e46-9a15-cd486d36fade.jpg<br> https://www.stdaily.com/web/gdxw/pic/2026-07/22/551741_t1_1X0X600X337_c0aa8a04-64a0-4e46-9a15-cd486d36fade.jpg<br> https://www.stdaily.com/web/gdxw/pic/2026-07/22/551741_t1_1X0X600X337_c0aa8a04-64a0-4e46-9a15-cd486d36fade.jpg<br> https://www.stdaily.com/web/gdxw/pic/2026-07/22/551741_t1_1X0X600X337_c0aa8a04-64a0-4e46-9a15-cd486d36fade.jpghttps://www.stdaily.com/web/gdxw/2026-07/22/content_551741.htmlnull科技日报100/enpproperty-->
