摘要
用贵州高原粳的广亲和和特亲和资源矮化后代与两系不育系测配，筛选出基本是特亲和资源后代的组合，证明亚种间特亲和资源有利于亚种间杂种优势的利用。
The compatibilty of rice(O. Sativa )was divided into four types:wide compatibility,special compatibilty,wide no compatibility and special no compatibility.For certainvariety,the compatibility depended on test variety and its cultvated environment of F1.Through a great deal of crossing between shorten lines of wide compatibility and specialcompatibility varietles ofGuizhou and two-line abortive lines,after the sifting procedure.most of the remained were the combinations betwcen two-lines and shorten lines from special compatibility resources of Guizhor These reslts showed that the special compatibility variety was more useful to the hybride rice.
