Selection responses and advantages of DSQ(Direct selection of QTL) over TBS(Trait-based Selection) in 10 nonoverlapping generations under varied heritabilities were theoretically studied by Monte Carlo simulation method in this paper.

• 从理论上采用蒙特卡罗(Monte Carlo)模拟的方法研究了不同遗传力条件下数量性状位点的直接选择(DSQ)和以表型为基础的选择(TBS)在10个不重叠世代中的选择反应以及DSQ相对于TBS的优势。
