【摘要】 本研究检测了13个微卫星标记与家兔生产性状(产仔数、初生窝重、21天窝重、28天窝重、90天重)间的相关性,试验动物包括齐卡巨型兔、齐卡大型兔、齐卡巨型兔与齐卡大型兔的杂交后代、齐兴肉兔与齐卡大型兔的杂交后代、加利福尼亚兔和齐兴肉兔。研究结果表明,13个微卫星标记中有5个标记与家兔生产性状相关。位点5L1E8 及 D7Utr5不同基因型除对初生重影响不显著外(P＞0．05),位点19L1G5除对产仔数影响不显著外(P＞0．05),分别对其余四个性状的影响均达到显著水平(P＜0．05)；而位点 D3Utr2和 DOUtr7 对五个生产性状均达到显著影响(P＜0．05)。其余8位点对各性状影响均未达到显著水平(P＞0．05)。如果试验动物的样本量增加后这些结果能够被重复,这些基因位点将可能作为各生产性能的遗传标记,用于选种工作,以提高选种的准确性,加快遗传进展。更多还原

【Abstract】 In this study,thirteen microsatellite DNA makers were genotyped to test their association with economic traits among 6 meat rabbit populations, including California rabbit,Qixing rabbit,Germany great line of ZIKA,New Zealand of ZIKA Rabbit, Qixing rabbit×New Zealand of ZIKA Rabbit,Germany great line of ZIKA×New Zealand of ZIKA Rabbit.We found that 5 markers were significantly associated with one or more economic traits.Statistical significance was reached between 5L1E8 and D7Utr2 with born Litter number,21st day litter weight,28th day litter weight and 90th day individual weight. Association was also observed between the marker 19L1G5 and firstborn Litter weight,21st day litter weight,28th day litter weight and 90th day weight with p＜0.05.In addition,markers D3Utr2 and D0Utr7 were associated with each of the five genomic traits (p＜0.05).If these results can be confirmed in other studies with larger sample size,these genetic loci could be used as genetic markers for breeding and selection in future.更多还原
