Cross breeding and selection are still the major methods to breed new ornamental cultivars. With the progress in biotechnology, some new breeding methods including genetic engineering have become the focus of the ornamental plant breeding, and gained many researchs on varietal improvement. ornamental plant; conventional breeding; biotechnological breeding; genetic engineering 1 1 900 530 20 15 220 195 33 11 500 294 60 35 20 80 40 32 27 7080 15 15 45 37 6 6 40 25 10 7 12 9 50 35 105 65 1980 150 65 400 230 600 180 500 90 600 60 300 113 2002-11-14 1977-
