Embodiment 1

[0028] A hybrid breeding method of yew, including the following steps:

[0029] (1) Pollen collection: Determine the male and female plants of Southern yew (Taxuswallichianavar.mairei) and Media (Taxus×media), and investigate the specific time of flowering. The results showed that the initial flowering period of the male flowers of Taxus chinensis was more than 10 days earlier than that of Taxus media. The initial flowering period of the female flowers was basically the same; the spitting period of the female flowers of the two yews was 2 days, and the spitting period of the whole female flowers lasted about 2 weeks. . The pollen of the male plant of Taxus chinensis var. mairei was collected in mid-February, and the pollen of the male plant of Taxus Media was collected in late February. The pollen was naturally dried, and the impurities were removed and placed in an EP tube at 4°C for refrigeration and kept dry.

[0030] (2) Pollination: From March 1st, observe the spitting of fem...

Abstract

The invention discloses a hybridization breeding method of taxus chinensis. The hybridization breeding method comprises the following steps: collecting pollens, pollinating, fertilizing, fruiting, storing in sand, sowing and transplanting. With the adoption of the hybridization breeding method, the problem that pollination and breeding are difficult, caused by the fact that flowering phases of taxus chinensis plant seeds are unsynchronized, is solved; the method is simple and feasible; and a lot of production practices can be carried out by adopting a spraying manner. The hybridization breeding method of the taxus chinensis has important and profound meanings on deep development and wide application of taxus chinensis plant resources, and has a wide application prospect.

Description

Technical field [0001] The invention relates to a hybrid breeding method of plants, in particular to a hybrid breeding method of yew, belonging to the technical field of woody plant species selection. Background technique [0002] Taxus chinensis, also known as yew, is a precious tree species protected by the state, and its natural forest resources have been exhausted. Taxus chinensis is an evergreen tree with straight trunks, beautiful tree appearance, red when the seeds are mature, and bright fake skin. It is an excellent bonsai and green tree species. The yew wood is durable and has beautiful texture. The roots and stems are all high-grade carving materials. It is a special forest material. Its roots, stems, bark and leaves contain paclitaxel, which is recognized as a cancer drug in the world today. It relieves menstruation, diuresis and lowers blood pressure. It has obvious effects on the prevention and treatment of diabetes and cardiovascular diseases. It is a valuable medi...
