QTL Mapping of Growth Traits in Yellow River Carp (Cyprinus carpio haematopterus) at 5–17 Months after Hatching

To screen the quantitative trait loci (QTL) and genes related to growth of Yellow River carp (Cyprinus carpio haematopterus) after removing maternal effect, we established a family these carps. Four growth-related traits (body length, height, thickness, weight) at 5 17 months hatching (MAH) were measured. Analysis QTL mapping for four was conducted using genetic linkage map constructed in our laboratory. We identified 47 that three consensus (cQTL). A total 10, 14, 13 associated with body weight, respectively; cQTL-1, cQTL-2, cQTL-3 contained 11, 2, 2 QTL, respectively. detected candidate within 50 Kb upstream downstream five main-effect (phenotypic variation explained > 10%, logarithm odds 5.5). Two (cbfa2t2 neca1) may be affected by effects comparing 5–17 MAH. This study first attempt eliminate carp. These results can used molecular marker-assisted breeding provide valuable genomic resources mechanisms underlying
