F₁ hybrids were made between inbreds derived from Chinese cabbage, Brassica campestris ssp. pekircensis (green leaf, no development of lateral bud) and Korean turnip, ssp. raga (purple leaf, development of lateral bud). Then they were selfed and backcrossed to both parents to obtain F₂, BCP₁ and BCP₂ seeds, respectively. Seeds of each generation were sown and cultivated in the fall season to investigate the inheritance of the lateral bud development and leaf color. The purple color was found to be dominant over the green color and controlled by a single gene. Lateral bud development was dominant over no development and found to be controlled by duplicate genes. The genes governing the two characters were independent. The gene symbols were proposed to be $quot;A-$quot; for the purple leaf and $quot;aa$quot; for the green leaf and $quot;Lb, -, - -$quot; and$quot; - -, Lb₂ -$quot; for lateral bud development and $quot;lb₁lb₁lb₂lb₂$quot; for no development of the lateral bud.
