High-quality ramie variety breeding method

The invention relates to the technical field of ramie variety breeding, and provides a high-quality ramie variety breeding method which comprises the following steps: F1 generation: repeatedly hybridizing a'vertical field 'ramie variety introduced from Japan with local ramie, selecting parents with stable hereditary characters for sexual hybridization, screening excellent single plants from breeding, and culturing into a high-quality ramie variety; meanwhile, parent materials are required to have the characteristics of drought resistance and disease resistance by cross parents; and F2 generation: screening the F1 generation variety, and selecting the variety of which the single fiber count in three seasons is averagely greater than 1800m/g and the single fiber strength is greater than 57.85 CN. According to the method, an outdoor planting field natural identification method and indoor cultivation screening are adopted, the five continuous generations of the ramie variety are subjected to directional breeding,
