摘要(Abstract)：

利用265个AFLP标记、127个微卫星分子标记、37个EST-SSR标记和16个RAPD标记(共445个标记)对大头鲤/荷包红鲤抗寒品系的F2代雌核发育群体44个个体进行基因型检测,构建鲤鱼(Cyprinus carpio L.)遗传连锁图谱;利用软件WinQTLCart2.5采用复合区间作图法对体重和体长两个性状进行了QTL定位分析。结果共检测到与两个与体重性状相关的QTL,分别定位到LG24连锁群(qBWh-24-1)和LG20连锁群(qBWh-20-1)上,可解释的表型变异分别为7.98%和20.05%;检测到两个与体长性状相关的QTL,分别位于LG2连锁群(qFS-2-1)和LG20连锁群(qFS-20-1),可解释的表型变异分别为5.69%和12.69%,4个QTL的加性效应均为负值。
