摘要： 前言 生物资源是自然资源的重要组成部分,它不但是人类赖以生存的物质基础,也在自然界良性生态循环中扮演着重要的角色。地方品种资源则是人们在自然和经济条件制约下长期劳动的结晶,是庞大的种质基因库。长期以来,我国对品种资源的研究还比较落后,手段较少,新技术应用不多,本实验室利用遗传标记性状(红细胞抗原)对我国的地方鸡种

Abstract: By use of seven operationally monospecific sera of chicken (see Annual Report of the Institute of Genetics, Academia Sinica, 1981", p. 34-35), analyses of constitutions of flocks and genetic relationship were studied among some breeds of "White Plumage Ukokkei" (Chinese native chicken breeds). Comparative studies on "Peking Yukei" (Chinese native chicken breed) and White Leghorn Beijing Line 1 were also carried out. The experiment results denoted as follows:First, 7 blood-group factors in the same breed of domestic fowl inter different genie factors or in the same genie factor of the different breeds were measured. The significant differences were found among distribution frequencies of the blood-group factors (P<0.01). Second, the highest and lowest distribution frequency of blood-group factors are specific in each breed. Third, the amount of constitutive type of blood-group factors and their frequencies varied with flocks. It means that genetic constitutions of different flocks are different.The coefficients of homozygosity of blood-group gene in these flocks are lower (0.1519-0.1768).The genetic distances (calculated by the distribution frequency of the blood-group factors) of some "White Plumage Ukokkei" are smaller, but their genetic similarities are larger. On the contrary, the genetic distances between some "White Plumage Ukokkei" and White Leghorn Beijing Line I are larger, but their genetic similarities are small, whereas the genetic distances, between all the breeds described above and "Peking-Yukei" are of intermediate type.
