A method for creating upright and compact germplasm resources of cabbage sprouts that are not affected by the environment

Abstract

An environmental-impact-free method for creating upright and compact type germplasm resources of Chinese flowering cabbage is characterized in that a Suzhou green type common Chinese cabbage inbred line Q2, a Suzhou green type Chinese flowering cabbage inbred line G11 as well as Lubao 60 tian Chinese flowering cabbage G5 from conventional varieties of Guangdong Chinese flowering cabbage are taken as parent materials, and the method comprises the following steps: G5 as a female parent and Q2 as a male parent are hybridized, and first-filial generation seeds 1F1 are obtained; G5 as a recurrent parent and 1F1 as the male parent are backcrossed, and BC1F1 is obtained; BC1F2 is obtained through selfing of BC1F1; plants with the compact plant type in BC1F2 are selected for selfing, and BC1F3 is obtained; G11 as the female parent is hybridized with BC1F3, 2F1 is obtained, and BC1F4 is obtained through selfing of BC1F3; 2F1 as the female parent is hybridized with BC1F4, and 3F1 is obtained; plants with the compact plant type in 3F1 are selected for selfing, and 3F2 is obtained; plants with the compact plant type, upright blades and glossy dark green stalk color and free of lateral buds in 3F2 are selected for selfing, and 3F3 is obtained. The upright and compact type germplasm resources of the Chinese flowering cabbage are free of environmental impact during planting and integrate excellent commodity character genes such as no lateral buds, glossy dark green stalk color, no wax powder, shorter petioles and the like.

Description

technical field [0001] The invention relates to the field of vegetable breeding, in particular to a method for creating upright and compact germplasm resources of cabbage sprouts that are not affected by the environment. Background technique [0002] In terms of plant taxonomy, cabbage belongs to Brassicaceae Brassica species Brassica non-heading cabbage subspecies cabbage variety, also known as cabbage heart, cabbage tip, and cabbage mustard. The edible organs are flower sprouts and attached sprout leaves, which are the original The characteristic vegetables produced in our country are one of the types of vegetables that ordinary people like to eat. In the long-term cultivation process, some local varieties groups specially used for producing cabbage sprouts have been formed, such as red cabbage sprouts in Hubei, cabbage sprouts in Guangdong, and other local varieties, such as Shanghai Yidaoqi, Yangzhou cabbage sprouts, etc. . [0003] Usually, the more the leaves of the ...

AI Technical Summary

Problems solved by technology

In order to have cabbage on the market in other seasons, in recent years, cabbage native to South China (namely Cantonese cabbage) has been introduced. Due to the obvious difference in taste and local cabbage tip, the market acceptance is not high and the development is relatively slow. Existing cabbage varieties are difficult to solve this technical problem. It is necessary to breed varieties suitable for Suzhou consumption habits to solve the above technical problems. It is necessary to create germplasm resources suitable for Suzhou consumption taste to meet breeding needs

[0006] To sum up, in order to significantly improve the yield and quality of cabbage sprouts, a large number of upright compact germplasm resources of cabbage sprouts without lateral buds that are not affected by the environment are needed as the breeding basis. There are no public reports on related methods. Secondly, in order to expand the consumption area of ​​cabbage sprouts It is also necessary to create germplasm resources suitable for local consumption needs, and there is no public report on how to aggregate them together. It is necessary to independently invent a kind of upright compact germplasm resources of cabbage sprouts without lateral buds that are not affected by the environment. method
