中蜂与意蜂营养杂交对意蜂微卫星遗传多态性的影响

通过人工添加中华蜜蜂王浆技术来培育江山2号与法国意蜂的杂交蜂王,并测定江山2号、法国意蜂、中华蜜蜂、营养杂交子1代和子4代工蜂的微卫星遗传多态性。结果表明,经过营养杂交,亲本蜜蜂与营养杂交子代的遗传距离发生明显的变化,中华蜜蜂和意大利蜜蜂的特有DNA条带发生了转移。说明通过蜂种之间的营养杂交可以改变其微卫星多态性。

Effects of Microsatellite Genetic Polymorphisms of Apis mellifera ligustica on Nutritional Crossbreed between Apis cerana cerana and Apis mellifera ligustica

In this paper,we breed hybridizing queen of the Jiangshan honey bee No.2 and French Apis mellifera ligustica through the technology of artificially feeding royal jelly of Apis cerana cerana, and then the genetic polymorphisms of microsatellite of the workers were measured. The workers were from the Jiangshan honey bee No.2 colonies, French Apis mellifera ligustica colonies, local Apis cerana cerana colonies, the 1 hybridizing offspring as well as the 4 consecutive hybridizing offspring of nutritional crossbreeding French Apis.merllifera.L queen and the Jiangshan honey bee No.2 drone colonies. The results showed that the genetic distance of parents and hybridizing offspring was varied, and the unique DNA bands of Apis cerana cerana and Apis mellifera ligustica were shifted.
