摘 要 ：通过对“Ch型”谷子显性核不育的遗传研究，证实“Ch型”的不育性与“澳大利亚谷”的细胞质无关，其育性是受两对显性连锁基因Ms-和Rf-上位互作控制的。其中Ms是显性不育基因，Rf是显性上位基因，当二者共同存在时，显性上位基因能抑制显性不育基因的表达，从而使不育表现可育。这种由杂交而来，并能找到“恢复系”的显性核不

Abstract:Results of our studies revealed that the inheritance of the "Ch-" dominant nucleus sterility of millet has nothing to do with the cytoplasm of "Australia millet". Its fertility is controlled by two pairs of linked dominant genes Ms-and Rf- having epistatic interaction. Ms- is a domminant sterile gen
