    Abstract:
    This paper reports the results of blood-group and plasma protein polymorphism of eleven Chinese native fowl breeds. 1. The distribution frequencies of the blood-group genes (3 loci 12 alleles) in eleven Chinese native fowl breeds were significantly different in A and C loci, but not significant in B locus. The coefficients of homozygosity of blood-group gene in all breeds were almost similar, except in Gushi and Chonren pitted chickens. The distribution of blood-group factors in all breeds was extensive, and this means that the selection potential in these local breeds was very large. 2. The gene frequencies of alkaline phosphatase (Akp and Akp-2) transferrin (Tf) in some breeds were more different, while that of esterase (Es-1) was less different. Among Chinese Japanese and American-European native breeds, the difference of gene frequencies of esterase was greater, while that of alkaline phosphatase and transferrin was smaller. It showed the identity or diversity in breed origin and evolution in these Chinese local breeds and Japanese or American-European native breeds. 3. The cluster analysis of the eleven Chinese native fowl breeds showed that these breeds could be divided into four groups: White ear-lobe- Shouguang- Luyuan chickens; Xiaoshan-Xianju- Pudong chickens; Langshan- Taihe Silky- Beijing Youkei chickens and Gushi-Chonren pitted chickens.
