As PTDT does in threshold traits, PTDT is valid not only for different QTL effect level, but also for maker with multiple alleles and multiple tightly linked markers.(2) Under an appropriate selection ratio s (in this study, s is 0.2, 0.4, 0.6, 0.8, respectively), the power of PTDT can be improved and the genotying individuals can be decreased using selective genotyping design. However, the power of PTDT is related with population size and population structure, an appropriate selection ratio can be defined by simulation based on the existing data.(3) Among the three transforming methods, mixed-family selection is the best, full-sib selection has same power to mixed-family selection in many parameter combinations, and Estimated Breeding Value selection is inferior to them.

数量性状QTL定位的模拟研究结果表明：(1)数量性状经有效转化后，PTDT对数量性状QTL定位保持了阈性状QTL定位的稳健与高效，对不同效应大小的QTL(10％，30％，50％)PTDT都是一个有效的分析方法；(2)在多等位基因标记、多标记方面，PTDT的检验功效与阐性状分析时一样高效；(3)在合适的选择率下(本研究的分别为0.2，0.4，0.6，0.8，1.0)，选择性基因型测定不仅可以减少基因型测定的数量，而且可以提高PTDT的检验功效，但选择性基因型测定的PTDT检验功效很大程度上与群体大小和结构有关，这个可根据具体情况通过模拟找到一个合适的选择率；(4)三种转化方法的转化效力结果表明，家系内混合家系选择的转化效力最高，家系内全同胞选择次之，估计育种值选择的转化效力较差。
