Embodiment 1

[0030] The genetic breeding method of Mandia yew comprises the steps:

[0031](1) Pollen collection: Determine the male and female plants of Taxus wallichianavar.mairei and Taxus × media, and investigate the specific time of flowering. It was found that the male flowering period of the southern yew is more than 10 days earlier than that of the Mandia yew, and the female flowering period is basically the same; the watering period of the single female flower of the two kinds of yews is 2 days, and the watering period of the whole female flower lasts for about 2 weeks . The pollen of the male Taxus chinensis plant was collected in mid-February, and the pollen of the male Taxus chinensis plant was collected in late February, and dried naturally. After removing impurities, they were stored in EP tubes and refrigerated at 4°C for later use, and kept dry.

[0032] (2) Pollination: From March 1st, observe the water spit of female flowers on the female plants of Taxus chinensis and Ta...

Abstract

The invention discloses a genetic breeding method for Taxus media. The genetic breeding method comprises the steps of pollen gathering, pollination, fertilization, fruiting, sand storage, sowing and transplanting. The genetic breeding method solves the problem of pollination and breeding difficulties caused by non-synchronous florescence of Taxus mairei plant species and is simple and feasible, and a large amount of production practice is performed in a spraying manner. The genetic breeding method has great and profound significance in deep development and wide application of Taxus media plant resources and has broad application prospect.

Description

technical field [0001] The invention relates to a genetic breeding method of plants, in particular to a genetic breeding method of Taxus chinensis, belonging to the technical field of woody plant variety breeding. Background technique [0002] Forest tree genetics and breeding generally refer to the following research: forest genetics, the genetic variation rules and evolution mechanisms of different traits of forest trees at the population, individual, cell and molecular levels, providing a theoretical basis for the conservation and management of forest resources and the genetic improvement of forest trees. Genetic improvement of forest trees, strategies and procedures for tree improvement, formulation of breeding programs, theories and methods of introduction, selective breeding, hybrid breeding (including yield, quality, resistance and adaptive breeding, etc.), and methods and methods of forest tree breeding. Forestry biotechnology, using biotechnology such as genetic eng...
