| 摘 要： | 多数学者已认定亚洲栽培稻（ＯｒｙｚａｓａｔｉｖａＬ．）的祖先是普通野生稻（Ｏ．ｒｕｆｉｐｏｇｏｎ）。然而栽培稻的籼、粳分化是发生在驯化之前还是在驯化之后，也即普通野生稻是否存在籼、粳分化的问题，是十几年来稻作起源研究中争论的热点之一。Ｓｅｃｏｎｄ［１］用多个同工酶位点的分析结果得出结论，普通野生稻在驯化为栽培稻之前就已经发生了籼、粳分化，即有籼型普通野生稻和粳型普通野生稻之分。Ｍｏｒｉｓｈｉｍａ和Ｇａｄｒｉｎａｂ［２］用２４个形态和生理性状及１２个同工酶位点和杂交亲合力等方法证明普通野生稻没有发…

| Abstract: | Ninety accessions which included Chinese common wild rice (Oryza rufipogon) from 8 provinces and traditional cultivars from lower and middle basins of Yangtze River, southeast of China and Yunnan Province as well as some commercial varieties were analyzed by RAPD with 24 primers. A scattered figure suggesting the indica japonica and wild domestication differentiations among 90 rice accessions was generated based on RAPD data. The results indicated that Chinese common wild rice, indica and japonica accessions were divided into 3 groups respectively. Chinese common wild rice were somewhat closer to the japonica type than the indica type. |
