General crossing schedule layout (example). In each generation, a number of plants are grown and screened for the desired target genotype(s). Crossings are then performed to provide new offspring to be grown, genotyped and selected for use in the next generation. All targets and crossings are fixed in advance. This example has 3 parental genotypes A, B and C. Initially, A and B are crossed to produce an intermediate target genotype D. In the next generation, D is crossed with parental genotype C to create the ideotype I.
