Heredity analysis of coat color in Suhuai pigs

Suhuai pig,a new lean line of Xinhuai pig,was selected and bred from excellent hybrids whose parents are Big Yorkshine and Xinhuai pig. In this article, the separative phenomenon of coat color of Suhuai pig was analyzed. The result showed very complicated heredity of coat color. The coat color is not only controlled by polygene, but also has interaction among the loci. However, the white and black gene frequency could increase through serious selection in descendants of Homogeneity parents, although it is difficult to clean other coat color gene.
