China is the natural distribution center of Lilium. In this land, there are 47 varieties and 18 varieties of native lilies, which play a very important role in the improvement of the world lily variety. However, there are less than half of the original Lily species used in breeding, and there are many Lily species with special traits that need further development and utilization. Researchers in China’s research and teaching units have conducted detailed analysis and research on the progress of Chinese lily variety improvement and biotechnology research. The advantages of Chinese Lily are obvious: Mao Lili, Northeast Lily and other flowers stand upright and the plant is tall. It is suitable for cultivating varieties of cut flowers. Lily, Lily, Lily, Lily, Lily, Ligustrum, Lilium, Lilium are all small. It is suitable for the cultivation of miniature potted varieties; Hubei Lily, Mao Lily, Shandan and Lijiang Lily are important parents for disease-resistant breeding. Some lilies can be used for cold-resistant breeding, and some can be used for heat-resistant breeding. These rich and colorful original species are important parents that improve lily plant type, resistance, etc. through cross breeding. Biotechnology is mainly used in the in vitro preservation of germplasm resources in the improvement of lily varieties, in vitro embryo culture to overcome the incompatibility of distant hybridization, anther culture and haploid breeding, the use of transgenic technology for the targeted modification of traits, and the rapidity of improved varieties. Breeding and so on. The combination of biotechnology and conventional breeding makes the prospect of lily breeding a broad prospect. Among the new cultivars of lilies, crossbreeding methods are used in most of the new cultivars. A considerable number of them are far-sourced hybrids, and promising results have been obtained in the field of breeding. Flowers, flowers, and flowers are the main goals of flower breeding. Lily has a variety of colors but lacks bright red and blue purple. The upright trumpet type of the lily pattern is the main goal of flower type improvement. Increasing the aroma of Asian lilies and reducing the aroma of oriental lilies is the goal of aroma breeding. In the flowering period, the main varieties of early flowers and late flowers were selected to extend the flowering period and the viewing period. In the plant type, the cut flower varieties require tall plants, and the miniature pot varieties require short plants. Stress resistance is also an important goal of breeding. In addition, factors such as vase life, no pollen, and reproductive ability should also be considered. According to experts, genes related to disease resistance were transferred to cultivars, and plants with excellent ornamental value and strong resistance were selected. For ethylene-sensitive species and varieties, ethylene metabolism can be controlled through genetic engineering to extend the vase life. No pollen related to male sterility, the introduction of male sterility genes, is expected to solve the problem of pollen contamination of lily. In order to realize the rapid propagation of lily hybrid seedlings, tissue culture technology will have a great deal.
