[Genetic diversity of duck breeds: a study with microsatellite markers].
Thirty two microsatellite markers were utilized to analyze the genetic diversity and germplasm characteristics of five Fujian native duck breeds (Jinding duck, Liancheng white duck, Putian black duck, Shanma duck, and Muscovy duck) and two reference duck breeds (Beijing duck and Khaki Campbell duck). By using the markers, 371 alleles in test duck breeds were detected. The average allelic number per locus was 11.719, average value of PIC was 0.522, average number of effective alleles was from 5.141 to 6.961, and average heterozygosity was from 0.512 to 0.700. Based on Nei's standard distance (D(S)) and DA genetic distance, a dendrogram was constructed by using the unweighted pair group method with arithmetic mean (UPGMA). Jinding duck, Putian black duck, Liancheng white duck, Shanma duck, and Khaki Campbell duck were clustered into a group, and Beijing duck and Muscovy duck were clustered into another two groups, respectively. The dendrogram of D(A) and D(S) genetic distances were accorded with the real relations among the seven duck breeds.
