| 摘 要： | 采用多重PCR扩增结合荧光标记全自动电泳检测技术, 对鸡基因组1号染色体和Z染色体上20个微卫星座位与丝羽乌骨鸡BM、BF两个蛋用新品系180个个体的开产性状进行相关性分析。结果表明: 位于1号染色体上的MCW0068、MCW0200与开产蛋重相关显著(P<0.05); 位于1号染色体上的MCW0068、MCW0208和位于Z染色体上的MCW0128与开产体重相关显著(P<0.05); 而位于Z染色体上的MCW0154与开产体重相关极显著(P<0.01)。

| Abstract: | Twenty microsatellite loci on Chromosome 1 and Chromosome Z were selected from chicken genome for correlation analysis with traits at first laying in silkies. The 180 silkies were from two egg-laying lines of BM and BF. Genotyping of microsatellite loci was carried out by using fluorescein-labeled multiplex-PCR detection technology. The results showed that MCW0068 and MCW0200 on Chromosome 1 were significantly associated with egg weight at first laying (Plt;0.05), MCW0068 and MCW0208 on Chromosome 1 and MCW0128 on Chromosome Z were significantly associated with body weight at first laying (Plt;0.05), and MCW0154 on Chromosome Z was highly significantly associated with body weight at first laying (Plt;0.01). |
