银杏濒危?保护种质资源不止是保护种子
Ren Min Ri Bao· 2025-12-28 04:31
作为种业创新的源头和基础,种质资源在粮食安全领域的地位分外凸显。"杂交水稻之父"袁隆平在创 立"三系杂交水稻"技术时,需要运用雄性不育系、保持系、恢复系3种不同功能的水稻亲本配合实现杂 交育种。得益于1970 年在海南发现的雄性不育野生稻"野败",我国杂交水稻发展才掀开崭新一页。 1979年,李振声院士牵头的课题组经过20多年攻关育成小麦新品种"小偃6号",其凭借有效抵抗小麦条 锈病、产量高、品质好等特点成为我国小麦育种的重要骨干亲本。可以说,我国农业的重大发展突破, 都与关键性种质资源的发现、研究与利用息息相关。 2021年《种业振兴行动方案》实施以来,我国种源安全水平稳步提升,种业科技创新进入世界第一方 阵。抗稻飞虱水稻、耐密宜机收玉米等一批重大新品种问世,过去主要依靠国外的西蓝花等品种实现自 主选育,越来越多的优质中国种子破土而出、茁壮成长。农作物自主选育品种面积占比95%以上,国家 级种业基地供种保障率达80%,种质资源"家底"更厚,为充实"米袋子"、提稳"菜篮子"、丰富"果盘 子"打下坚实基础。 也要看到,我国是种质资源大国,但还不是种质资源强国,尚存种质资源精准鉴定利用不足、突破性品 种不多等短板 ...
