Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.
