Problems solved by technology

Since the comparison, identification and screening of offspring populations in the breeding process are carried out under open-field cultivation conditions, although under natural conditions, there are many and complex types of pathogens, and cabbage materials are easily infected by various pathogens, the occurrence and severity of diseases are still related to The temperature and humidity conditions are closely related, so there are problems such as stress resistance, disease resistance, and quality traits under open field cultivation conditions.
Although there is also an artificial inoculation method at the seedling stage to identify the disease resistance of cabbage materials, this method is not only labor-inten

Example Embodiment

[0020] Example one

[0021] Material: H-60 ​​(source: Nozaki Seed Plant in Japan, sold by Zhenjiang Ruifan Agronomic Co., Ltd.), Qiangli 50 (source: sold by Kobayashi Corporation of Japan and Wuhan Jiutou Bird Seed Industry Company).

[0022] For the process mode of this embodiment, see figure 1 , Which is specifically bred according to the following steps:

[0023] Step one, select the female parent. The H-60 ​​cabbage was sown and cultivated in the early autumn of 1998, and the excellent single plants with good growth, round leaf bulbs and strong disease resistance were selected for retention, and the flowering period was carried out in the following spring. The seeds were obtained by selfing during the budding stage. The seeds obtained were sown in the autumn of 1999 and then planted in a greenhouse. A total of 42 plants were planted. The relative humidity in the shed was artificially controlled at 75%-85% and the temperature was 22℃-30℃. At the adult plant stage, select excelle...

Abstract

The invention relates to a method for breeding cabbage and producing seeds, in particular to a method for breeding disease resistant cabbage and producing seeds, which belongs to the technical field of plant breeding. In the invention, environment conditions for arousing diseases easily are created in the breeding stage of cabbage so as to breed high-temperature-resistance, high-humidity-resistance and high-disease-resistance hybrid seeds. Compared with the conventional breeding method, passive quality detection is converted into high-quality seed screening and the controllability is high. Inaspect of disease identification, the method is more complete, more accurate, simpler, more convenient and easier to implement than a manual inoculation method.

Description

technical field [0001] The invention relates to a breeding and seed production method of cabbage, in particular to a breeding and seed production method of disease-resistant cabbage, belonging to the technical field of plant breeding and seed production. Background technique [0002] Cabbage is an important vegetable widely grown in various parts of our country, and plays an important role in vegetable cultivation and supply. So far, although my country's cabbage disease-resistant breeding has made great progress and remarkable results, there is still a certain gap in terms of current vegetable production and market demand, and compared with the advanced technology of cabbage genetics and breeding in developed countries. . In recent years, with the change of consumption demand, the area of ​​protected cultivation and off-season cultivation has been expanding year by year, which puts forward higher requirements for cabbage varieties. For example, in terms of disease resistan...
