Embodiment 1

[0046] A method for improving the efficiency of Chinese cabbage germplasm creation, specifically comprising the steps of:

[0047] S1, preparation of rootstock and scion: choose the hybrid variety with strong resistance, easy germination, and hypertrophic root as the rootstock material, choose the spring cabbage hybrid variety with beautiful appearance, good quality, yellow heart, and bolting resistance as the scion material, and then the rootstock And scion seeds are sown in 50 hole seedling trays in mid-December, are placed in solar greenhouse, make rootstock can pass vernalization smoothly.

[0048] In the step S1, the rootstock variety is "Weibai No. 2" provided by Weifang Academy of Agricultural Sciences, and the cabbage variety "Weibai No. 2" is normally sold on the market.

[0049] The scion variety is the Weixian Chinese cabbage hybrid variety "Weichunbai No. 3", which is provided by the Weifang Academy of Agricultural Sciences. The "Weichunbai No. 3" cabbage variety i...

Abstract

The invention discloses a method for improving the germplasm creation efficiency of Chinese cabbage. The method specifically comprises the following steps: S1, preparation of stocks and scions: selecting a hybrid variety with a large root as a stock material, selecting a bolting-resistant spring Chinese cabbage hybrid variety as a scion material, and sowing and vernalizing stock and scion seeds; S2, field planting; S3, grafting environment management: enabling plants to grow by controlling the environment temperature to be 15-20 DEG C, and irrigating roots with a chlormequat chloride diluent when the plants sprout for 20 cm; S4, grafting condition selection: taking second primary branches of the stocks as grafting parts, and selecting primary branches with the length of 6-10 cm as the scion; S5, grafting: grafting scion buds on the stock plants; and S6, management after grafting: after grafting is completed, managing grafted plants by controlling the growth environment temperature. The method can effectively improve the embryogenesis rate of free microspores of the material difficult to embryogenesis, accelerate the purification speed of the Chinese cabbage material and improve the germplasm creation efficiency.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for improving the germplasm creation efficiency of Chinese cabbage. Background technique [0002] my country is the origin of Chinese cabbage (Raphanus sativus L.) and has a long history of cultivation; Chinese cabbage resources are relatively abundant in my country; such as "Jiaozhou Chinese cabbage" in Qingdao, "Huangbud Chinese cabbage" in Weifang, etc. [0003] In recent years, with the improvement of people's living standards and the development of domestic and foreign situations, people's consumption habits of Chinese cabbage have also changed, and spring cabbage has gradually increased, and higher requirements have been put forward for the quality of Chinese cabbage; Due to the differences in the quality and the backwardness of the technical level, the breeding of spring Chinese cabbage varieties is slow. South Korean spring Chinese cabbage vari...
