Abstract
选用36个随机引物对“寒丰A”、“寒丰B”、“8204A”、“8204B”、“R161”等5份杂交粳稻亲本材料进行RAPD扩增,对其中特异RAPD标记片段进行克隆和测序。根据获得的特异DNA序列设计序列特征扩增区(SCAR)特异的引物,将18个RAPD标记转化成6个稳定的SCAR标记。用这些SCAR标记对亲本和杂种F1代单株进行检测,实验室检测种子纯度的结果与海南田间种植的结果基本一致。此外,应用水稻细胞质雄性不育特异的1对PCR引物,分辨出2对不育系/保持系亲本:“寒丰A”与“寒丰B”、“8204A”与“8204B”。上海市科技兴农重点攻关项目[农科攻字(2000)号第1-3号];; 上海市农业科学院青年科技基金(2000-09-02-1
