Method for rapidly cultivating purified strain of Dendrobium candidum with red leaves and red stems

The invention provides a method for rapidly cultivating a purified strain of Dendrobium candidum with red leaves and red stems. The method for rapidly cultivating the purified strain of the Dendrobiumcandidum with red leaves and red stems comprises the following steps: (1) acquisition of a hybrid fruit with germplasm of red leaves and red stems; 2) aseptic seeding; (3) in-bottle induction of traits of red leaves and red stems; (4) rapid purification and propagation through in-bottle bud cutting of the Dendrobium candidum with red leaves and red stems; and (5) rooting culture of the Dendrobiumcandidum with red leaves and red stems. The method provided by the invention requires simple equipment, and has the effects of rapidly screening and purifying the strain of the Dendrobiu.m candidum with red leaves and red stems. Compared with conventional variety breeding for the Dendrobium candidum with red leaves and red stems, a variety breeding cycle can be shortened from 3-5 years to less than 2 years, genotypes of s
