摘　　要：采用水平式淀粉凝胶是电泳技术，对云南盐津乌鸡３４只个体共计３４个基因座位的血液蛋白及同工酶多态性研究，发现了ＬＡＰ，ＡＫＰ－１，ＡＫＰ－２，ＣＫｓ－１，ＰＥＰ－Ｂ５个座位具有多态性，多态座位百分比和平均杂合度分别为Ｐ＝０．１４７０，Ｈ＝０．０５８６，对多态座位基因频率进行计算发现盐津乌鸡ＬＡＰ＾Ｂ，ａＫＰ－１，ＡＫＰ－２，ＣＥｓ－１＾Ａ，ＰＥＰ－Ｂ＾Ａ频率较高。In the present study,the horizontal starch gel electrophoresis was used toanalyze 34 gene ioci from 34 Yanjin black一bone chickens.The polymorphisms werefound only in LAP,AKP一1,AKP一2,CEs一1,PEP一B The percentage ofpolymorphic loci(p)nand the average heterozy gosity(H)were 0.147 and 0.0586respectively.Gene frequencies of polymorphic loci were calculated and found higher inLAPB,aKP一1,AKP一2°,CES-1A,PEP一BA,The results showed that the geneticdiversity of Yunjin black一bone chicken is higher,the special genotypies exist in thechicken.The Yunnan Yanjin black一bone chicken is a local breed with low level of selec-tion,have great potentialities for breeding and possess great values of protection
