Problems solved by technology

After the spheroids or clustered buds are irradiated and then transferred to the culture medium, the materials are easily polluted by the outside world, and the lethality rate increases
[0006] However, there is no report in the prior art on the use of radiation breeding technology to breed new varieties of Jinzhiyuye. When the radiation breeding method reported in the above-mentioned patents is used to select new varieties of Jinzhiyuye, the mutation rate is all low, and only one is bred. New varieties, breeding cycle is also long, up to 4 years, the effect is not ideal

Embodiment 1

[0036] Embodiment 1 The breeding method of golden branch jade leaf color leaf variety of the present invention

[0037] 1. Obtain the tissue culture seedlings of Jinzhiyuye

[0038]The plump young stems of the vigorously growing Jinzhiyu leaves that year were inoculated with 0.5mg / L 6-BA, 0.05mg / LNAA, 5mg / L SNP, 0.8g / L colchicine, 30g / L sucrose and 7g / L agar MS medium for primary culture, followed by subculture and rooting culture, wherein the subculture medium contains 0.6mg / L 6-BA, 0.05mg / L NAA, 4mg / L SNP, 25g / L sucrose and 7.5g / L agar MS medium, the pH value is 5.9, the rooting medium contains 0.4mg / L 6-BA, 0.03mg / L NAA, 4mg / L SNP, 25g / L sucrose and 7.5g / L agar 1 / 2MS medium, the pH value is 5.9; take root and culture for 10-15d to obtain the tissue culture plantlets of Jinzhiyuye.

[0039] In the experiment, control plants were set up, no colchicine was added to the control plants in the primary culture, and the conditions of subculture and rooting culture were the same...

Embodiment 2

[0054] Embodiment 2 The breeding method of golden branch jade leaf color leaf variety of the present invention

[0055] The plump young stems of the vigorously growing Jinzhiyu leaves that year were inoculated with 0.5mg / L 6-BA, 0.05mg / LNAA, 5mg / L SNP, 0.5g / L colchicine, 30g / L sucrose and 7g / L agar MS medium. Through primary culture, subculture and three stages of rooting culture (the medium of subculture and rooting culture is the same as embodiment 1)). After rooting and culturing for 10-15 days, tissue-cultured seedlings of Jinzhiyuye were obtained.

[0056] The radiation treatment of the Jade japonica leaf tissue culture seedlings, the transplanting and observation of the radiation tissue culture seedlings, the screening and propagation methods of mutant plants are all the same as in Example 1.

Embodiment 3

[0057] Embodiment 3 The breeding method of golden branch jade leaf color leaf variety of the present invention

[0058] The plump young stems of the vigorously growing Jinzhiyu leaves that year were inoculated with 0.5mg / L 6-BA, 0.05mg / LNAA, 5mg / L SNP, 1g / L colchicine, 30g / L sucrose and 7g / L agar MS medium. Through three stages of primary culture, subculture and rooting culture (the medium of subculture and rooting culture is the same as embodiment 1). After rooting and culturing for 10-15 days, tissue-cultured seedlings of Jinzhiyuye were obtained.

[0059] The radiation treatment of the Jade japonica leaf tissue culture seedlings, the transplanting and observation of the radiation tissue culture seedlings, the screening and propagation methods of mutant plants are all the same as in Example 1.

Abstract

The invention relates to the technical field of plant tissue culture, in particular to a breeding method of a golden branch jade leaf color leaf variety. The present invention combines tissue culture technology with two mutagenesis methods of colchicine chemical mutagenesis and radiation induction, which significantly improves the mutation rate of golden branch and jade leaves, shortens the breeding period, expands the variation range of plants at the same time, and reduces the impact of parents on The limitation of variation types provides a simple and efficient method for the breeding of new varieties of Jinzhiyuyecai, which enriches the planting resources of Euonymus.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture, and in particular relates to a breeding method of a golden branch jade leaf color leaf variety. Background technique [0002] Jinzhiyuye is a variety of Euonymus genus silk floss, a new variety of Euonymus developed by Henan Hongfeng Seedling Co., Ltd. It is a colorful deciduous tree with a height of 6-8 meters. The crown is round or oval, and the new leaves are tender in spring The branches are golden yellow, and turn red after frost in autumn. The fruit hangs all over the branches, and the orange-red arils are exposed after cracking, which is very beautiful. The branches and leaves of golden branches and jade leaves are beautiful and delicate, and their posture is graceful. They can be used as shade trees in gardens and greening at watersides. Jinzhiyu leaves are light-loving, slightly shade-tolerant; cold-resistant, drought-resistant, and water-humidity-resistant; well-developed ...
