| 摘 要： | 测定了青脚麻鸡与隐性白鸡杂交后自交的F2代个体的全净堂重、全净堂率、脂肪宽带、腹脂重和腹脂率6个胴体性状,检测10个微卫星DNA标记,对标记基因型胴体性状值进行方差分析和多重比较,结果表明:MCW328对于10周龄体重和全净膛重两性状各基因型均有显著的差异(P<0.05);ADL292对于腹脂重性状各基因型有极显著的差异(P<0.01),对于腹脂率有显著的差异(P<0.05)。MCW328标记基因与控制10周龄体重和全净膛重QTL连锁,ADL292标记基因与控制腹脂重和腹脂率QTL连锁。

| Abstract: | The six carcass traits including eviscerated weight,semieviscerated weight,fat distribution,abdominal fat weight and abdominal fat rate in F2 chicken individuals derived from a cross of spotted-cyan chicken with invisible-white chicken,were tested.In the study,ten microsatellite markers were determined.The values of carcass traits,which genotypes were marked,were calculated by using the methods variance analysis and multiple compare.The results showed that MCW328 had a significant difference with each genotype of live weight aged 10 weeks and eviscerated weight,respectively.ADL292 had a most significant difference with each genotype of abdominal fat weight,a significant difference with each genotype of abdominal fat rate.In addition, there was a linkage between the gene marked by MCW328 and the QTL controlling live weight aged 10 weeks and eviscerated weight,a linkage between the gene marked by ADL292 and the QTL controlling abdominal fat weight and abdominal fat rate. |
