湖北省部分家鸭群体遗传结构探讨

Genetic Structure Analysis of Indigenous Duck Breeds in Hubei Province

应用16个微卫星标记对湖北省3个家鸭群体共180个个体进行遗传多样性检测。结果表明:湖北省家鸭群体的遗传多样性较为丰富,其中,荆江麻鸭各项指标最高。F-统计量显示,群体间存在明显的遗传差异,有9.7%的遗传变异来自于群体间。Structure程序在预先未标明品种起源的条件下,准确将180个地方鸭个体划分3类,也真实反映了其在遗传上的差异,与各鸭种的选育历史及地理分布基本一致。

Genetic diversity and structure of indigenous duck breeds from Hubei province were investigated using 16 microsatellites DNA makers. The results showed that genetic diversity of Hubei province indigenous duck breeds was high,and Jingjiang Ma duck had highest value at each genetic index. From the result of F-statistic,considerable genetic differentiation was observed and 9.7% of the total genetic variation was from the breeds differences. Structure program divided correctely 180 individuals into 3 clusters on the condition that not labing the origin of individuals. The result was consistent with locations and breeding history of 3 duck breeds.
