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.
