Rapid breeding method of tillered onion

The invention discloses a rapid breeding method of tillered onion. The method comprises the following steps: cleaning and disinfecting the center position of the tillered onion, removing upper portion bulbs, reserving onion bulb stems containing main growing points, removing the main growing points and main growing point onion bulb stems, inducing adventitious buds, culturing the adventitious buds to form seedlings, and establishing a rapid breeding system of tillered onion bulb stems through optimizing the above culture process to obtain a large amount of nontoxic test tube seedlings. The system has the advantages of short breeding time, large breeding coefficient, high heredity stability, realization of rapid breeding of the tillered onion, provides low-price cost and low-time cost power guaranteeing for factory production of the tillered onion virus-free seedlings, and lays a foundation for industrialization of the virus-free tillered onion.
