1. Project Description: The technology of efficient and rapid propagation of plants without test tubes is a brand-new system of rapid propagation of plants. At the same time, this technology has made a double major breakthrough in the rapid propagation of plants in vitro in modern biotechnology and the conventional seedling raising technology used in human history in 2000. This technology is that many plants with one leaf and one bud are directly inoculated on the sand bed with simple field conditions, and they become seedlings at one time without any transplanting. Complete regenerated plants can be obtained at 4- 1 1 day, and one generation can be propagated every 30-60 days, and the propagation coefficient is greater than 2- 15, which is higher than the in vitro rapid propagation coefficient. Different plants can produce hundreds of thousands to millions of pure seedlings a year. Low cost and high benefit, and the input-output ratio is as high as 1: 5 or 1: 10.
2. Scope of application: this technology can be used for most plants that have been propagated by tissue culture, rapid propagation of shoot tips and conventional cutting seedling raising techniques, or plants that are not suitable for propagation; Can be used for fixing heterosis in plant breeding; Can be used for rapid propagation, popularization and protection of special transgenic plants (engineering plants), new germplasm materials or endangered economic plants; Can be used for the selection, purification and large-scale utilization of natural mutant plants, excellent single plants and polyploid dominant plant clones; Can be used for separation and propagation of virus-free seedlings; Can be used for the introduction and diffusion of new varieties at home and abroad.
3. Technical level: 1993, the efficient and rapid propagation technology of plants without test tubes has passed the appraisal of provincial experts; From 65438 to 0995, it was confirmed by patent publication (announcement), patent literature retrieval and novelty retrieval of China Academy of Agricultural Sciences that this technology was at the international leading level.
market prospect
With the worldwide flower industrialization and the development of economic forest in forestry production, the demand for afforestation and greening seedlings has increased sharply, and the demand for residents' vegetable baskets has changed from "big road vegetables" to specialty vegetables, which will give full play to the efficient and rapid propagation technology of plants in vitro, and will play a great role in improving the quality of economic crops, reducing planting costs and enhancing market competitiveness. The application of this technology will surely occupy a broad market in the whole country, saving the country a lot of foreign exchange for purchasing foreign improved varieties.
