摘要(Abstract)：
[目的]分析江苏省意大利蜂与中华蜜蜂品种间、品种内的遗传变异。[方法]利用6对微卫星DNA标记从DNA水平上对意大利蜂与中华蜜蜂进行遗传多样性分析,评估品种内的遗传变异和品种间的遗传分化。[结果]共检测到42个等位基因,每个位点的等位基因数从2到11不等,所有位点平均的期望杂合度和PIC值分别为0.505 0和0.473 1。意大利蜂和中华蜜蜂6个微卫星位点平均有效等位基因数分别为5.17和3.83,平均基因杂合度为0.500 7和0.333 2,群体分化系数为29.5%,两个品种间的Reynolds'遗传距离和Nm分别为0.330 5和0.638 4。[结论]两个蜜蜂品种均表现出较高的群体杂合度和丰富的遗传多样性。
