Multi-resistant high-quality Qingmaye type red-orange-core Chinese cabbage breeding method

Abstract

The invention discloses a multi-resistant high-quality Qingmaye type red-orange-core Chinese cabbage breeding method. Through the invention, a high-pile heading type TuMV antigen 322 is created by use of the TuMV antigen BP007 and TuMV antigen 826, a selfing line group 1 is created through small hybrid 50, and a self-incompatible line 05-514 is created by use of autumn green 55; hybrid screening is performed by use of the 322, group 1 and 05-514 as well as various red-orange-core materials, the required red-orange-core gene is led into the Qingmaye resource, and a new variety of the multi-resistant Qingmaye type red-orange-core Chinese cabbage is bred on the basis of maintaining the typical characteristics such as Maye type cyan stem, green leaves, no burr and the like. Through the methoddisclosed by the invention, the bred new variety has short childbearing period, strong combining ability, Maye type cyan stem, deep green outer leaves, spherical leaves and red orange core, middle walnut texture, high resistance to various diseases such as viral disease, downy mildew, soft rot, tipburn and the like, bright color, high carotenoid content and obviously higher nutritional values than common cabbage, and can be cultivated as a specific vegetable, thereby obviously increasing the value of garden truck.

Description

Technical field [0001] The invention relates to a Chinese cabbage hybrid breeding method, in particular to a Chinese cabbage breeding method with multi-resistance and high-quality green hemp leaf orange and red heart. Background technique [0002] At present, domestic Chinese cabbage breeding basically adopts heterosis utilization. Since the 1980s, domestic breeding units have bred a large number of autumn Chinese cabbage hybrids, and realized early, middle and late maturity matching, storage resistance, high quality, Each has its own characteristics such as strong disease resistance, but few varieties combine these advantages ("Chinese Chinese Cabbage"). Improving the quality of Chinese cabbage, enriching the variety of colors of Chinese cabbage, and satisfying various needs have become the new goal of breeding. Generally speaking, Chinese cabbage can be divided into spring cabbage, summer cabbage, early autumn cabbage (sale cabbage) and autumn and winter cabbage according to t...

Problems solved by technology

Due to the mild disease in Japan and South Korea and the lack of TuMV resistance sources, artificial inoculation of TuMV mainstream strains in my country's main Chinese cabbage production areas and field planting identification have reached a high sensitivity level, and it is impossible to achieve high and stable yields in my country.

There are many varieties of Yuhuangxin baby cabbage in Japan and South Korea, and this type of variety has not solved the problem of resistance to viral diseases, and it is impossible to achieve high and stable yields in severe disease areas such as Jinan
