水貂微卫星位点与毛皮性状相关的研究

Correlation of Microsatellite Sites and Fur Character of Mink

通过建立一般线性模型,对5个水貂群体、300个个体的4个经济性状与16个微卫星遗传标记位点进行相关性研究。结果表明:珍珠色水貂的Mvi4013的AA和BB针毛长度差异显著,A基因起正面效应。珍珠色水貂Mvi586的BB和CC、BC和CC之间的针毛直径差异显著,银蓝色水貂Mvi4015的AA和BB基因型、AB和BB基因型的绒毛长度之间差异显著,A基因起正面效应;Mvi4013的AA和AB基因型、AB和BB基因型的绒毛长度之间差异显著,Mvi4001 BB基因型的绒毛长度显著高于其他两种类型,B基因起正面效应。在金州黑水貂群体中Mvi4006的AC型与BD、CC型绒毛直径有显著差异,A基因起正面效应。在银蓝色水貂,Mvi2243的AA型和AB型绒毛直径差异显著,Mvi4001 AA型绒毛直径和AB基因型差异显著,B基因起负面效应。

The relation of 4 traits of 5 populations with 300 mink and 16 microsatellite markers was analyzed by GLM. The results showed that it was up to significant difference for awn length between AA type and BB type of Mvi4013 in Pearl mink, Mlele A played a positive role. It was up to significant difference （P 〈 0.05） for awn diameter between BB type and CC type, BC type and CC type of Mvi586 in Pearl mink. It was up to significant difference （ P 〈 0. 05） for vellus length between AA type and AB type, AB type and BB type of Mvi4013 in Silverblue mink, Allele A played a positive role. It was up to significant difference （ P 〈 0.05） for vellus length between AA type and BB type, AB type and BB type of Mvi4015 in Silverblue mink. It was up to significant difference （ P 〈 0.05） for vellus length between AA type and BB type, AB type and BB type of Mvi4001 in Silverblue mink. Allele B played a positive role. It was up to significant difference （ P 〈 0.05） for vellus diameter between AC type and BD type, AC type and CC type of Mvi4006 in Jinzhou mink, Allele A played a positive role. It was up to significant difference（ P 〈 0.05） for vellus diameter between AA type and AB type of Mvi4001 and Mvi2243 in Silverblue mink, Allele B played a negative role.
