摘要

摘要: 为探究微卫星标记与肉鸭生长性状杂种优势的相关关系,利用8个微卫星标记对M18母本、大型母本、中型母本、小型母本和番鸭进行遗传多态性检测。结果表明,8个微卫星标记座位平均有效等位基因数为2.888 1个,平均多态信息含量为0.633 1,平均基因杂合度为0.518 1;番鸭与M18母本、大型母本、中型母本、小型母本的遗传距离为0.445 2、0.362 3、0.367 1和0.322 4。根据遗传距离,采用对数曲线模型对白羽半番鸭体重杂种优势进行预测,T检验结果显示,预测结果与实测结果无显著性差异,表明本研究建立的根据微卫星标记预测白羽半番鸭部分生长阶段体重杂种优势是可行的。

Abstract: Genetic diversity of M18 parent,Large-female parent,Medium-female parent,Small-female parent and Muscovy ducks was studied using eight microsatellite markers in order to analyze the relationship of microsatellite polymorphisms and the heterosis of growth traits.The result indicated the average effective allele was 2.881,the average polymorphism information content was 0.6331,and the average gene heterozygosity was 0.5181.The genetic distances between muscovy duck with Large-female parent,Medium-female parent,Small-female parent were 0.4452,0.3623,0.3671 and 0.3224 respectively.According to the standard genetic distances,forecast the heterosis of mule duck by the model of logarithmic curve.There were no significant differences between the predicted results and the experimental determination by T test which demonstrated that using genetic polymorphism of microsatellite markers to forecast the heterosis of white-weather mule duck is practicable.
