Comprehensive breeding method for superior winter jujube seedlings

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.
