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.
