Abstract
Aiming at accelerating the application of molecular markers in the genetic improvement of quails, six EST-SSR markers were successfully developed using a bioinformatics method. Polymorphisms of three quail populations (Chinese yellow, China black and Korean quail) were detected. The results showed that there were 2-6 alleles in six EST-SSR markers. The mean polymorphism information contents of Chinese yellow , China blackand Korean quail were 0.5451, 0.4962 and 0.4937, respectively. The average heterozygosity values were 0.6134, 0.5759 and 0.5613. Among the six EST-SSR markers, three were highly polymorphicand the others were moderately polymorphic. The newly-developed six EST-SSR markers may be used to determine the genetic diversity of quails. The six EST-SSR markers identified were related to carbohydrate metabolism and melanin synthesis, but the specific mechanisms need to be further analyzed.
