摘要
基因组选择(Genomic selection,GS)技术在肉兔上的研究和应用都还显著落后于其他畜禽。为探究基因组选择在肉兔育种上的实际应用,研究以363只肉兔的84日龄体重为试验材料,结合全基因组范围内的87704个SNPs标记,构建线性混合模型;利用基因组最佳线性无偏预测(GBLUP)方法估计个体的基因组育种值,并采用5倍交叉验证法分析估计的准确性。结果表明:基因组估计育种值准确性最高为0.23,最低为0.01,平均值为0.12。该研究结果为在肉兔中开展基因组选择提供了参考。
The research and application of genomic selection(GS)technology in meat rabbits are significantly behind other livestock and poultry.In order to explore the practical application of genome selection in meat rabbit breeding,this study used the 84 day body weight of 363 meat rabbits as experimental materials,combined with 87704 SNPs markers in the whole genome,to construct a linear mixed model;Genome best linear unbiased prediction(GBLUP)method was used to estimate individual genome breeding value,and the accuracy of estimation was analyzed by 5-fold cross validation method.The results showed that the highest accuracy of genome estimation breeding value was 0.23,the lowest was0.01,and the average was 0.12.The results provide a useful reference for genome selection in meat rabbits.
