説明

This is the first study in which genetic diversity of eight chicken populations including Satsumadori, Satsuma-jidori and three populations each of improved and commercial chicken by using 102 indels markers. Both of Satsumadori and Satsuma-jidori were referred to as Satsuma’s chickens in this study. The proportion of polymorphic loci, average observed and expected heterozygosities were ranged from 0.500 to 0.814, from 0.147 to 0.257 and from 0.175 to 0.247, respectively. Monomorphic indels loci being specific to a particular population were detected in some populations. The coefficients of genetic differentiation (Gst) of the Satsuma’s chickens and six populations of improved and commercial chickens were 0.124 and 0.287, respectively. The Gst for all populations was 0.329. The (Ds) genetic distance matrixes for all possible pairs (28 pairs) of populations were estimated from allele frequency to construct UPGMA tree. The UPGMA tree clearly divided Satsuma’s chickens and the other populations. The 2-D scatter plots of PCA analysis assembled the individuals into their respective populations.
