Pre-basic seeds
The seeds of the generations preceding the basic seeds are designated by the expression "pre-basic seeds" and correspond to the generations between the starting material (G0) and the basic seed (G4).
Step 2
Basic seeds
The basic seeds (G4) are produced in a single generation, from the pre-basic seeds (G3).
Step 3
Seed production
Certified seeds come from the multiplication of basic seeds, there can be 2 series of multiplication which are R1 and R2.
Step 4
