EFFICIENT MUTAGENESIS METHOD FOR BREEDING APPLE POLYPLOID

The invention discloses an efficient mutation breeding method for apple polyploidy, and relates to the technical field of agricultural planting. Comprising the following steps: performing doubling culture on apple explants in a culture medium containing colchicine, a carbon nanomaterial and beer yeast cell walls, and performing tissue culture and subculture in the culture medium containing the carbon nanomaterial and the beer yeast cell walls. According to the cross breeding method, the rooting rate of cluster buds in the apple triploid breeding process can be increased, and then the utilization rate of high-quality germplasm resources is increased.
