[Studies of the blood-group of chicken. X. Analysis of blood-group and plasma protein polymorphism in eleven Chinese native fowl breeds].

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.

[Analysis of genetic relationship among Chinese native chicken breeds using microsatellites marker].

The allele frequencies, heterozygosity (H), mean heterozygosity, polymorphism information content (PIC) and genetic relationships were studied in Luyuan chicken, Gushi chicken, Tibetan chicken, Baier chicken, Xianju chicken, Chahua chicken, Dagu chicken,Beijing Fatty chicken, Langshan chicken, Henan Game chicken,Taihe Silkies chicken and Xiaoshan chicken using seven microsatellite DNA markers. The results showed that there were differences among allele fequencies of seven microsatellite loci in 12 Chinese native chicken breeds. Among the 12 Chinese native chicken breeds, mean heterozygosity of Luyuan chicken was the highest (0.5929), and that of Chahua chicken was the lowest (0.3514). There were similar results in PIC. By fuzzy cluster analysis was found that the genetic relationship between Taihe Silkies chicken and Henan Game chicken was the nearest, and that between Gushi chicken and the other chicken breeds was the most distant. The 12 Chinese native chicken breeds were divided into three group by fuzzy cluster analysis. The first group included Taihe Silkies chicken, Henan Game chicken, Langshan chicken, Xiaoshan chicken, Dagu chicken, Beijing Fatty chicken and Luyuan chicken, the second group included Chahua chicken, Tibetan chicken, Xianju chicken and Baier chicken, and the third group included Gushi chicken.
