Improvement of Lily catalyzed by Biotechnology
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.

Development Prospect and planting Technology of Edible Lily
I would like to ask the rural network experts: CCTV broadcast a special report on eating lilies, where can I find seeds to sell? Is there a demonstration base for reference? What are its development prospects? Is it difficult to grow? According to the current adjustment of rural industrial structure in China, the development of edible lily has a prospect, because it is also a new type of characteristic vegetable. At present, the development of edible lilies in West Orchard Township and Pengjiaguan Township in the suburbs of Lanzhou is the best, so as to become their dominant products. You can visit and study with them.

Bulb cultivation techniques of Oriental Lilium in mountainous area
In recent years, the production and consumption of cut lilies in China have increased rapidly, but the bulbs are still almost dependent on imports. Self-sufficiency of bulbs has become the "bottleneck" of controlling the production of cut lilies in China, so it is imperative to realize the localization of high-quality commercial seed balls of lilies. There are many geomorphological types in Zhejiang Province, and the use of temperature differences at different elevations is very beneficial to the bulb expansion and flower bud differentiation of bulb flowers. The cold cultivation in the mountain area of Zhejiang Province was selected to purify and rejuvenate the lily and breed the seed bulb, so as to solve the problem that the lily bulb could not be self-sufficient for a long time in our country.
