Common carp (Cyprinus carpio L.) is an important economic fish species with very rich resources, which have been used to develop many carp varieties in China. Because of the significant differences in the genetic back- ground among varieties, quantitative trait loci (QTLs) detected from one variety are difficult to use directly in another variety. In addition, it is impossible to construct a genetic map and detect QTL markers affecting important traits in every variety. Thus, it is a good selection strategy to verify QTLs in one variety and identify shared QTL markers. The methods will save time and money and can be used to detect QTLs quickly in different varieties. Mirror carp (Cyprinus carpio L.) and Jian carp (Cyprinus carpio var. jian) are two important Chinese aquaculture varieties that play an impor- tant role in selective breeding. Significant differences in body shape, growth rate, and growth scale have been found between Jian carp and mirror carp. Thousands of QTLs affecting important traits have been detected recently in differ- ent mirror carp panels. However, the number of Jian carp QTLs is very limited. In this study, 89 microsatellite markers were selected to identify markers associated with mirror carp traits. These markers were located at overlaps or flanks of QTL interval peaks affecting body weight, standard length, body height, and body thickness based on a genetic map containing 992 microsatellite markers. As a result, 54 QTL markers and 83 preferred genotypes were identified by as- sessing the contribution of different genotypes on traits. In addition, a mapping population containing 94 Jian carp was analyzed using these 54 QTL markers. Forty markers were polymorphic in Jian carp, with a percentage of 74.07%, which was higher than that of randomly selected markers. Correlation analysis results indicated that 22 markers were shared QTLs between mirror carp and Jian carp, and 18 of the shared markers were significantly correlated with the same trait in the two carp. Thirty preferred genotypes were detected in Jian carp, which will be useful for a marker-associated selection breeding program. The QTLs shared between strains can be used to reduce the effort and cost of QTL mapping in new common carp varieties.
