Abstract: In this study,992 microsatellite markers were selected to analyze the genomic DNA of 190 individuals derived from the sibling group of F1 hybrids mirror carp(Cyprinus carpio L.) The map was found to span 5138.2 cM over 51 linkage groups,with an average spacing of 5.19 cM.Then quantitative trait loci(QTLs) associated with Acid phosphatase(ACP) were identified by the interval mapping of the software MapQTL 6.0.Nine QTLs were identified for ACP on eight linkage groups.Among the nine QTLs controlling ACP in mirror carp,the maximum LOD score was found to be 5.37(LG24) in which 13.8% of the phenotypic variations were explained.By BLAST with the zebrafish for sequence alignment,molecular markers were found homologous with leucine-rich repeat-containing protein,transmembrane protein 50A,ADP-ribosylation factor and cytokine receptor family member b8 in zebrafish.The findings could be well used for molecular marker assisted selection and for disease control in mirror carp.
