Embodiment 1

[0022] Embodiment 1: a kind of Chinese cabbage hybrid breeding cultivation method comprises the following steps:

[0023] 1) Parental selection: the selected varieties include at least Liangqing Chinese cabbage and Xiaoza 56;

[0024] 2) Parental self-separation: Liangqing Chinese cabbage was used to self-separate offspring, and an excellent individual plant A was selected; self-separated offspring from Xiaoza 56 was selected to select an excellent individual plant B;

[0025] 3) Parental self-purification: A self-incompatible line with stable and consistent traits, resistance to viral diseases, downy mildew and soft rot was selected as the offspring C after five generations of self-purification; B was selected after five generations of self-purification A self-incompatible line resistant to viral disease and soft rot was produced as the offspring D;

[0026] 4) Hybridization: Do reciprocal cross compatibility test with offspring C and offspring D, and finally cross the femal...

Embodiment 2

[0027] Example 2: Insect pollination is used in the parent self-separation, parent self-purification and hybridization processes.

Embodiment 3

[0028] Embodiment 3: In the self-cross separation of the parents, the self-crossing purification of the parents and the hybridization process, an insect net is set around the test field; the insect net allows pollinating insects to enter the test field to form insect pollination; the insect net only allows pollination The entry of insects into the experimental field can not only control pests to a certain extent, but also improve the effect of insect pollination.

Abstract

The invention discloses a hybrid breeding and cultivation method for cabbage. The method comprises the following steps: 1) parental selection: selecting at least Liangqing cabbage and Xiaoza 56; 2) parental selfing and separating: separating the progeny from the selfing process of Liangqing cabbage and selecting a good individual A, and separating the progeny from the selfing process of Xiaoza 56and selecting a good individual B; 3) parental selfing and purifying: selfing and purifying the individual A for five generations, and selecting antiviral and downy mildew resistant and soft rot resistant self-incompatible lines with consistent traits as progeny C; selfing and purifying the individual B for five generations, and selecting antiviral and downy mildew resistant self-incompatible lines as progeny D; 4) hybridizing: performing a reciprocal cross compatibility test with progeny generations C and D, and performing hybridization with generation C as female parent and generation D as male parent, to obtain the cabbage seed. The technical solution provided by the invention solves the problem that the cabbage species currently introduced to Yunnan, Guizhou, Sichuan have poor qualityand low yield when being planted in spring and autumn.

Description

technical field [0001] The invention relates to the technical field of cabbage planting, in particular to a Chinese cabbage hybrid breeding cultivation method. Background technique [0002] Chinese cabbage is a leafy vegetable of the genus Brassica in the family Brassicaceae. It is native to northern my country and later introduced to the south. It is planted in the three provinces of Yunnan, Guizhou, and Sichuan. At present, there are many types of Chinese cabbage, but after being introduced to the three provinces of Yunnan, Guizhou, and Sichuan Cabbage varieties still have many problems in terms of yield, growth cycle, bolting resistance, heat and humidity resistance, and comprehensive disease resistance; the Chinese cabbage species introduced to Yunnan, Guizhou and Sichuan still have single-season quality when they are planted in spring and autumn. Poor, low yield issues. Contents of the invention [0003] The purpose of the present invention is to provide a Chinese cabb...
