Application 2.2.2 Tool 4.5 - Cross Algorithm

Algorithm for selecting the generative method based on the breeding status of parents

Let GF, GM, GFF, GFM, GMF and GMM be the germplasm records for the female parent, male parent female grand parents and male grand parents respectively.
Let GC be the germplasm record for teh cross GF/GM.
