采用淀粉凝胶电泳和聚丙烯酰胺凝胶电泳技术，对亚洲8个国家（中国云南、蒙古、尼泊尔、越南、老挝、泰国、缅甸、印度尼西亚）的1,112个样品和两个改良品种（伊萨布朗、鲍里斯布朗）的360个样品的7个蛋白色蛋白基因座的遗传变异进行了研究。在亚洲地方鸡群体中发现了5个蛋白色蛋白基因座（OvG（3）、G（2）、G（1）和Tf EW）的多态性。亚洲本地群体的多态位点比例（P-poly）和平均杂合度（H）分别为0.143 ~ 0.714和0.014 ~ 0.225，均高于改良品种。亚洲18个地方鸡群的细分指数（G（ST））值（0.0827）低于改良鸡群（0.1693）。这一值意味着亚洲本地种群的细分程度低于改良品种，亚洲种群之间的基因构成相似。
Genetic variations of seven egg white protein loci in 1,112 samples from eight Asian countries (Yunnan province of China, Mongolia, Nepal, Vietnam, Laos, Thailand, Myanmar, Indonesia) and 360 samples from two improved breeds (Isa Brown, Boris Brown) were investigated by using starch gel and polyacrylamide gel electrophoresis. Five egg white protein loci (Ov G(3), G(2), G(1) and Tf-EW) were found to be polymorphic in Asian native chicken populations. The proportion of polymorphic loci (P-poly) and average heterozygosity (H) of Asian native populations varied from 0.143 to 0.714 and 0.014 to 0.225, respectively, and were higher than those of improved breeds. The subdivision index (G(ST)) value among 18 native chicken populations in Asia is lower (0.0827) than among improved chicken populations (0.1693). This value means that the degree of subdivision among Asian native populations is lower than among improved breeds and gene constitutions among populations in Asia are similar.
