“种质”就是“种子”吗?这里有权威答案!
Nan Fang Nong Cun Bao· 2026-02-11 04:06
【现象】 如今,银杏在一些城市很常见,为何仍处于濒危等级?实际上,濒危的是"野生银杏"而非"景观银杏", 前者种群数量稀少,后者基因相同或相近,依靠它们无法增加银杏的基因多样性。这反映出种质资源多 样性的重要意义。 【点评】 种质资源,是指携带生物遗传信息且具有实际或潜在利用价值的载体。"种质"就是"种子"吗?实际上, 二者不能画等号。 就拿农作物种质资源来说,其涵盖农作物的栽培种、野生种和濒危稀有种的繁殖材料等,形态不仅有果 实、籽粒,还有苗、根、茎、叶、芽、花,同时还包括组织、细胞和DNA、DNA片段及基因等有生命 的物质材料。可见,种质资源的范畴比种子大得多。种业是农业的"芯片",种质资源的重要性不可小 视。 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 ...
