The invention belongs to propagation expanding protection technologies of plant resources, and particularly relates to a method for quickly breeding rare specific tea germplasm. The method for quickly breeding the rare specific tea germplasm comprises the following steps of 1, scion collection and freshness retaining; 2, grafting and management; 3, management after grafting; 4, scion maintenance, collection and freshness retaining; 5, cuttage; 6, management after cuttage. Grafted new branches are directly taken as cuttage scions, the features of quick growth of grafting are utilized for propagation expanding of the cuttage scions, and the number of seedlings formed through cuttage seedling raising is guaranteed.
