chinois. ［目的］对宁夏六盘山区黄牛杂交改良群体生长激素受体（GHR）基因的多态性进行分析，为宁夏黄牛杂交改良选育提供理论参考。［方法］采用聚合酶链式反应-限制性片段长度多态性方法（PCR-RFLP）对该群体70个个体的GHR基因多态性进行检测。［结果］扩增出了338 bp的目的片段，PCR产物被限制性内切酶Alu I消化后表现出多态性，其中AA基因型频率为75.71%；BB基因型频率为24.29%。［结论］ 共检测到AA和BB 2种基因型，六盘山区黄牛杂交改良群体GHR基因具有多态性。

After digested by restriction enzyme Alu I, the PCR product showed polymorphisms. The frequencies of the two genotypes (AA, BB) were 75.71% (53 individuals) and 24.29% (17 individuals), respectively. ［Conclusion］ Two genotypes of GHR gene were detected in improved hybrid yellow cattle from Liupan Mountain area in Ningxia._
