Embodiment

[0039] Embodiment: a kind of method for radish grafting preservation material, specifically comprises the following steps:

[0040] (1) Rootstock preparation: select hybrid varieties with good disease resistance and drought resistance as rootstock materials; select radish inbred varieties that need to be preserved as scion materials, and then sow rootstock and scion seeds in 50 holes in mid-December Seedling trays are placed in the solar greenhouse; when the temperature is low, a small shed is built in the greenhouse and covered with a second film to control the temperature of the greenhouse at above 0°C and below 10°C; so that the rootstock can pass vernalization smoothly.

[0041] In this example, the variety selected as the rootstock material is "Wei radish No. 1 seed", and the Wei radish No. 1 seed is provided by Weifang Academy of Agricultural Sciences, and "Wei radish No. 1 seed" is normally sold on the market.

[0042] In this embodiment, the scion material is selected ...

Embodiment 2

[0064] A method for radish grafting and preserving materials, specifically comprising the following steps: (1), rootstock preparation: selecting a variety of "Wei radish No. 1 seed" as a rootstock material; selecting a radish inbred variety that needs to be preserved as a scion material, and then The rootstock and scion seeds were sown in 50-hole seedling trays in mid-December and placed in the solar greenhouse; when the temperature was low, the greenhouse temperature was controlled above 0°C and below 10°C by building a small shed in the greenhouse and covering it with a second film; The rootstock can pass vernalization smoothly.

[0065] (2) Colonization: In the first ten days of March, rootstocks and scion plants are planted in the shed when they are just about to bolt, with a row spacing of 1m and a plant spacing of 1m, which is convenient for netting and releasing bees for self-pollination; The radishes are completely buried in the soil.

[0066] (3) Environmental manage...

Embodiment 3

[0082] A method for radish grafting preservation materials, specifically comprising the steps of:

[0083] (1) Rootstock preparation: select the variety "Weixian radish No. 1" as the rootstock material; select a single plant (disease plant) of the radish inbred line "Weixian radish" that needs to be preserved as the scion material, and then use the rootstock and scion seeds Sow seeds in 50-hole seedling trays in mid-December and place them in the solar greenhouse; when the temperature is low, build a small shed in the greenhouse and cover the second film to control the temperature of the greenhouse above 0°C and below 10°C; so that the rootstock can pass through the spring smoothly. change.

[0084] (2) Colonization: In the first ten days of March, rootstocks and scion plants are planted in the shed when they are just about to bolt, with a row spacing of 1m and a plant spacing of 1m, which is convenient for netting and releasing bees for self-pollination; The radishes are com...

Abstract

The invention discloses a radish grafting material preservation method, which comprises the following steps: an early-stage field planting step, a grafting management step, a grafting step and a post-grafting management step, in the early-stage field planting step, radish hybrid seeds with strong disease resistance and drought tolerance are used as stock materials, radish inbred line lateral branches needing to be preserved are used as scion materials, and the radish selfing line lateral branches are used as scion materials; in the grafting management step, the environment temperature is controlled to be 15-20 DEG C, meanwhile, a chlormequat chloride diluent is used for root irrigation, so that internodes of plants are shortened, tissues are compact, in the grafting step, scion buds are grafted on stock plants, and in the post-grafting management step, the grafted plants are managed by controlling the growth environment temperature, so that the grafted plants can be successfully mature to harvest seeds, the survival rate of the radish grafting material can be effectively increased, the effect is remarkable, and the method is suitable for preservation of radish germplasm materials and has wide application value.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for grafting radish preservation materials. Background technique [0002] my country is one of the origins of radish (Raphanus sativus L.), and radish has been cultivated in China for more than 2700 years. Studies have shown that Shandong Luzhong, Luxi mountainous area and Huanghuai area are the origins of radish in my country. my country's perennial planting area is about 18 million mu; my country's radish resources are relatively rich, there are more than 80 high-quality local varieties of fruit radish resources, and the distribution is relatively scattered, mainly in Shandong, Jiangsu, Hebei and other places; such as Shandong'Weixian Radish', Beijing'xinmei radish', Tianjin'Weiqing radish' and so on. [0003] During the long-term self-seeding process of inbred line materials, while retaining a large amount of good quality, it is prone to degeneratio...
