Problems solved by technology

In addition, grafting at the seedling stage requires a lot of labor, and each crop needs to be grafted once, which requires a lot of labor.
[0005] So far, there have been no reports about the interspecific hybridization of Solanaceae plants and the cultivation of high-quality Solanaceae rootstock varieties

Abstract

The invention provides a kind of nightshade and its cultivation method, rapid propagation method and application. The cultivation method comprises: using wild nightshade as the female parent and wild nightshade as the male parent, after hybridization and pollination, embryo rescue and It can be obtained after transplanting hardened seedlings. The present invention specifically selects wild nightshade as the female parent, uses wild water eggplant as the male parent, and the tree eggplant variety obtained by hybridization has fast growth, well-developed trunk, strong growth potential, perennial, strong photosynthesis, and strong nutrient and water absorption capacity. High affinity with scion, rootstock scion interface heals quickly and well; good resistance, can resist soil-borne diseases such as Fusarium wilt, Verticillium wilt, bacterial wilt and root-knot nematode; its rapid propagation method is operable Strong, high efficiency, and easy to promote in practical applications; it has a wide range of uses, it can be used as a rootstock for grafting solanaceous plants such as eggplant, tomato, potato and tobacco, and can be used as a landscape tree for green planting in the south.

Description

technical field [0001] The invention belongs to the technical field of genetic breeding, and more specifically relates to a nightshade and its cultivation method, rapid propagation method and application. Background technique [0002] Solanaceae plants include eggplant, tomato, pepper, potato and tobacco, etc., which are commonly used crops in human life. In commercial seedlings of Solanaceae including tomato and eggplant, wild eggplant is often used as rootstock to resist the occurrence of soil-borne Solanaceae diseases and insect pests. [0003] According to reports in the prior art, soil-infectious pathogens of Solanaceae plants can survive in the soil for as long as 5-7 years, and are difficult to control through the application of pesticides. Therefore, it is of great practical significance to cultivate Solanaceae rootstock varieties that can resist pests, grow fast and have high grafting compatibility. Grafting cultivation with rootstocks and scions is an economical ...
