CLUSTER ANALYSIS OF THE FAMILIES IN YUEHUANO CHICKEH

Fuzzy cluster analysis of 13 families in Yuehuang chicken was made on the basis of the polymorphisms at 10 bleed protein loci (Akp - 1, Akp-2, Amy - 1, Amy-2, Es-1, Es-2, Hb- 1, Hb-2, Pas and Tf ) in an experiment. The result of this analysis was compared with that of the systematic cluster analysis tastd on 9 quantitative traits. It is believed that the cluster analysis based on the protoin polymorphisms is significant for line breeding in Yuehuang chicken and that each of two cluster analysis methods has its advantages for application. The genelic structure of these families and variabilities among them were also studied.
