The crossing schemes for the different MAGIC populations are shown in Figure 1a and 1b.
To pyramid several new QTLs, stepwise crossing schemes can be designed, although such schemes can require many generations of breeding.
The first simulates the selection of diverse founder parents and the second the influence of multi-parent crossing schemes (and number of founders) on haplotype creation and diversity.

More complex crossing schemes involving 6-way, 8-way crosses or diallel selective mating for use in breeding of self - pollinated crops were proposed many years ago (Allard 1960; Jensen 1970) but have seldom been used in plant breeding programs.
A burdensome disadvantage to genetic studies of postzygotic isolation is that the phenotype of interest, sterility or inviability, precludes direct genetic crossing schemes.
