HEAVY ION MUTATION BREEDING METHOD FOR GLYCINEMAX

Disclosed is a heavy ion mutation breeding method for Glycinemax, relating to the technical field of agriculture, including S1: selecting screened superior Glycinemax seeds as a parent variety, and exposing to a heavy ion radiation source to induce a mutation in a genome; S2: collecting the irradiated variant Glycinemax seeds, and performing seed treatment to promote the development of mutants; S3: seeding and cultivating the treated Glycinemax seeds into seedlings; and S4: selecting plants exhibiting target traits from the seedlings, and performing single plant selection. The heavy ion mutation breeding method can introduce a large number of new genetic variations in Glycinemax populations, which may include a single gene mutation, a multi-gene combined mutation, etc., thereby increasing the Glycinemax genetic diversity. This genetic diversity helps to improve the adaptability and survival ability of Glycinemax populations and makes them have stronger growth and survival competitiveness under different environmental conditions.
