图3 杜洛克品种早期选择 该图展示杜洛克品种早期选择的部分结果。SSGBLUP方法估计育种值时,基础群体有1000张芯片、测试群有700张芯片;基于最优秀的前1%（有终测表型时的GEBV排名）个体保留比例进行早期选择效果评估

Fig. 3 The performance of early-stage prediction in Duroc The figure shows the partial results of early-stage prediction in Duroc. The SSGBLUP were used to estimate the EBVs on the basic of 1000 genotyped pigs in base population and 700 genotyped pigs in test population. The performance evaluation of early-stage depended on the ration whether top 1% excellent individuals were kept or not that have off-test phenotype
