Last Updated: 2024/11/24, China is the natural distribution center of Lilium. In this land, there are 47 varieties and 18 varieties of original lilies, which plays a very important role in the improvement of lily varieties in the world. However, at present, less than half of the original species of lily are used in breeding, and there are still many original species of lily with special and excellent characters that need to be further developed and utilized. Researchers from scientific research and teaching institutions in China have made a detailed analysis and research on the progress of lily variety improvement and biotechnology research in China. The advantage of Chinese lily is obvious: Mao lily, northeast lily and so on.

China is the natural distribution center of Lilium. There are 47 varieties and 18 varieties of lily in this land, which occupy a very important position in the improvement of lily varieties in the world. However, less than half of lily stock is used in breeding at present, and many lily stock with special excellent characters need to be further developed and utilized. The researchers of scientific research and teaching units in China have carried out detailed analysis and research on the improvement of lily varieties and the progress of biotechnology research in China.

Lily of China has obvious advantages: lily of China, lily of Northeast China, etc. have erect flowers and tall plants, which are suitable for cultivating cut flowers; lily of China, lily of China, lily of China, Some lilies can be used for cold resistance breeding, and some can be used for heat resistance breeding. These rich and colorful original seeds are important parents to improve lily plant type and resistance through cross breeding. Biotechnology is mainly applied in the in vitro conservation of germplasm resources, in vitro embryo culture to overcome distant cross incompatibility, anther culture and haploid breeding, directional modification of traits by transgenic technology, and rapid breeding of improved varieties. The combination of biotechnology and conventional breeding makes lily breeding work have broad prospects.

Most of the new lily varieties were bred by cross breeding, and quite a few of them were distant hybridization, which made gratifying achievements in breeding field. Flower color, flower fragrance and flower type are the main objectives of flower breeding. Although lily has various colors, it lacks bright red and blue purple. The erect trumpet type of lily flower type is the main target of flower type improvement. Increasing the aroma of Asiatic lily and decreasing the aroma of Oriental lily were the goals of aroma breeding. In florescence, early flowering and late flowering varieties were selected to prolong florescence and ornamental period. In plant type, cut flower varieties require tall plants, while miniature potted varieties require short plants. Stress tolerance is also an important goal of breeding.

In addition, factors such as vase life, pollen absence and reproductive capacity should be considered. Experts introduced that disease-resistant genes will be transferred into cultivated varieties, from which both excellent ornamental value and strong resistance plants will be screened. Ethylene sensitive species and varieties can be genetically engineered to control ethylene metabolism and prolong vase life. There is no correlation between pollen and male sterility. Introducing male sterility gene is expected to solve the problem of lily pollen pollution. In order to realize the rapid propagation of lily hybrid seedlings, tissue culture technology will have great achievements.
