Problems solved by technology

And the breeding technology of present high-quality winter jujube tree is not high, mostly utilizes tissue culture to breed purely, and this breeding method has the shortcoming of long breeding cycle, high technical cost, low reproductive coefficient, and poor disease and stress resistance.
As a result, the survival rate of winter jujube saplings is low in cultivation, and the plant growth is not strong, resulting in serious problems such as low yield, poor quality, and even no fruit in production.

Embodiment Construction

[0026] The following examples are further detailed descriptions of the present invention.

[0027] Example:

[0028] 1. Project implementation location

[0029] The field breeding of Dongzao seedlings is carried out in the China High-tech Seedling Breeding Farm under the Dongzao Research Institute of Zhanhua County.

[0030] 2. Project implementation scale

[0031] The different stages of the project research range from small to large. The scale of each material is about 1,000 square meters, and the scale is expanded to the development stage.

[0032] 3. Project implementation method

[0033] (1) Inoculation of explants: During the growing season, cut 2 cm of newly germinated jujube branches or terminal buds of secondary branches, rinse them with sterile water, and then disinfect them with 70% alcohol on an ultra-clean bench for 5 seconds, and use 5% sodium hypochlorite and 0.1% mercuric chloride were sterilized for 8 minutes respectively, and finally rinsed with sterile w...

Abstract

The invention discloses a comprehensive breeding method for superior winter jujube seedlings. The method is characterized in that tissues of a winter jujube plant are removed from a plant body under an aseptic condition, and the tissues are placed in a glass container in which light, temperature, moisture and nutrients are controlled manually for culturing, so that the tissues live or develop continually and are developed into a complete winter jujube plant finally; breeding is performed under an indoor manually-controlled environmental condition, asexual propagation is performed, and rapid propagation and production can be realized; manual control is adopted, and is not influenced by seasons; land is saved; the screening performance is high, and virus-free seedlings can be bred; greater convenience is brought to purification and selection of varieties. Zhanhua brumal jujube nursery stocks produced with the method can keep superior properties of a parent body, are free viruses, and have high disease resistance and stress resistance; the nursery stocks are robust, are short in internodes, and are developed in root systems; a full productive age is entered in advance, and the fruiting quality is high.

Description

technical field [0001] The invention relates to a plant breeding method, in particular to a method for comprehensive breeding of winter jujube high-quality seedlings. Background technique [0002] Dongzao is a high-quality late-maturing fresh jujube variety. The fruit resembles a small apple. The skin is thin and the flesh is crispy. The taste is sweet and slightly sour. It is known as the "king of fruit"; Dongzao is also rich in cyclic adenosine monophosphate, which has high health value, so it is loved by people. Since the end of the 1990s, winter jujube has developed in my country. However, there are fewer high-quality winter jujube trees in newly developed winter jujube production areas in my country, and the quality of winter jujubes in the winter jujube population is uneven, and there are more low-quality winter jujubes. And the breeding technology of present high-quality winter jujube tree is not high, mostly utilizes tissue culture to breed purely, and this breeding...
