Schematic representation of the development of the 208 MDP lines. In total, 1000 irradiated seeds of each of seven soybean cultivars were sown in a research field of KAERI. Seeds from the 1695 M₂ plants were harvested and first selected for 523 mutant lines in the M₅ generation based on agricultural traits such as grain yield, growth type, and climate adaptability. In a second selection phase in the M₁₂ generation, 208 genetically fixed mutants were selected to eliminate redundant phenotypes from the 523 mutant lines (additional information is described in [30]).
