| 摘 要： | 现在发现的广亲和品种不是万能的,池桥宏的 S_5~n 模型由于不能解释籼粳杂交所产生的不育到可育连续分布的复杂现象,因而其局限性。我们根据栽培稻分类进化与起源中的研究结果,认为广亲和基因与地理分布相联系,广亲和品种主要分布在起源演化的中心地区,它们很可能是籼粳没有完全分化,栽培稻进化初级阶段的产物。广亲和酯酶谱的特征是7A10A,7A11A 和7A13A。

| Abstract: | The wide compatibility varieties(WCVs)discovered are not flawless.The S-5~n model of Ike- hashi and Araki also has its limitation,because it could not explain the complicated phenomenon of fertility- sterility of cross between indica and japonica.Based on studies on the origin,evolution and taxonomy of culti- vated rice,we suggest wide compatibility is a characteristics realted to geographical locations,for WCVs were distributed mainly in the centers of origin and differentiation of rice.It is very likely t... |
