Power of QTL detection 1- β ∗ of joint composite interval mapping model 1 with cofactor selection method 1 for 40 double haploid nested association mapping (DH-NAM) vs. 40 backcross nested association mapping (BC-NAM) vs. 40 nest association mapping based on recombinant inbred lines (RIL-NAM) subpopulations at different α ∗ levels in a scenario with 50 QTLs and heritability h 2= 0.8. The 40 DH-NAM, BC-NAM or RIL-NAM subpopulations were randomly selected from a total of 50 relevant DH-NAM, BC-NAM, or RIL-NAM subpopulations. Colors indicate the DH-NAM, BC-NAM or RIL-NAM population. Vertical lines at each point indicate the standard errors
