Tree tomato as well as cultivation method, rapid propagation method and application thereof

Abstract

The invention provides a tree tomato as well as a cultivation method, a rapid propagation method and application thereof. The cultivation method of the tree tomato comprises the following steps of taking wild solanum wrightii as a female parent and wild solanum torvum as a male parent, and sequentially carrying out embryo rescue and acclimatization and transplantation after cross pollination to obtain the tree tomato. According to the tree tomato as well as the cultivation method, the rapid propagation method and the application thereof, the wild solanum wrightii is specifically selected as the female parent, the wild solanum torvum serves as the male parent, and the tree tomato variety obtained through hybridization is high in growth speed, developed in trunk, high in growth vigor, perennial, high in photosynthesis, high in nutrient and moisture absorption capacity, high in scion affinity, high in scion joint healing speed of stocks, good in healing, good in resistance, and capable ofresisting soil-borne diseases such as fusarium wilt, verticillium wilt, bacterial wilt and root-knot nematode disease; the rapid propagation method of the tree tomato is high in operability, high inefficiency and easy to popularize in practical application; and the tree tomato is wide in application, can be used as a stock for grafting solanaceae plants such as eggplants, tomatoes, potatoes andtobaccos, can be used as a landscape tree and is used for southern greening planting.

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 ...

AI Technical Summary

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
