GENETIC DIVERSITY OF YUNNAN LOCAL PIG BREEDS INFERRED FROM BLOOD PROTEIN ELECTROPHORESIS

Protein electrophoresis was used to examine the blood protein polymorp hism in Yunnan local pig breeds, i.e., the Saba pig, Dahe pig, and Dia nnan small-ear pig breeds, Of 38 genetic loci surveyed 9 were found to be polymorphic. The percentage of polymorphic loci (P) varies from 0. 1875 to 0.2121, and the mean individual heterozygosity (H) varies fron t 0.0712 to 0.1027 in three pig breeds. The results indicate that bloo d protein polymorphism in Yunnan pig breeds is high. Yunnan local pig breeds have a wealth of genetic diversity at the level of blood protei ns.
