中文摘要：
以112头皖南黑猪为研究对象，采用PCR．SSCP方法检测胆固醇酯转运蛋白（cholesteryl ester transfer protein，CETP）基因的多态性。结果表明：（1）皖南黑猪CETP基因第1内含子795碱基处发生c—T突变（C795T）；（2）在C795T突变位点中检测到CC、CT、TT3种基因型，其基因型频率分别为0．6250、0．3036和0．0714：C的基因频率为0．7768，T的基因频率为0．2232；（3）皖南黑猪CETP基因的多态信息含量（PIC）为0．2866，该位点处于中度多态；卡方检验表明，该位点的X^2值为1．7388，处于哈迪-温伯格平衡状态。
英文摘要：
One hundred and twelve pigs from Wannan Black population were used for detecting the poly- morphism of CETP gene by PCR-SSCP method. The results show as follows. （1） C〉T mutation （C795T） occurred in 795 base position of intron 1; （2） Three genotypes （CC, CT and TT） were found in C795T site, genotypic frequency of CC, CT and TT was 0.625 0, 0.303 6 and 0.071 4, respectively, gene frequency of C and T was 0.776 8 and 0.223 2, respectively; （3） The polymorphism information content （PIC） was 0.286 6 in Wannan Black popula- tion, which indicated it was moderate polymorphism. The X2 value was 1.738 8, which was in Hardy-Weinberg equilibrium in Wannan Black population （P〉0. 05）.
