Correlation analysis of microsatellite DNA markers with growth trait among 3 breeding populations of common carp

We screened out the molecular makers of 15 microsatellite loci for common carp(Cyprinus carpio), and compared these markers with Huanghe carp (Cyprinus carpio haematopterus Temminck et Schlegel), Jian carp (Cyprinus carpio var. jian) and Heilongjiang carp (Cyprinus carpio haematopterus) populations inaspects of body weight, body length, body width and body depth. The results based on GLM show that Mfw5 is significantly correlated with body depthfor Huanghe carp (P0.05). For Jian carp population, Hlj013, Cca09 and Mfw7 are significantly correlated with body weight, body length and body depth (P0.05); Mfw2 is significantly correlated with body weight and body width (P0.05); while Mfw29 is significantly correlated with bodyweight (P0.05). For Heilongjiang carp population, Mfw6 is significantly correlated with body weight, body length, body width and body depth (P0.05); Mfw4 is significantly correlated with body weight , body length and body depth (P0.05); Mfw11 is significantly correlated with body width and body depth (P0.05). Furthermore, the genes and genotypes related togrowth traits in the3 carp populations are found.
