Abstract

The invention discloses a method for selecting a transport-resistant mid-maturation new variety from CMS (cytoplasmic male sterile) and DH (double haploid) series of cabbages. The method includes the steps of selecting a CMS DH09-MP01-78CMS series from the cabbages to serve as a female parent; selecting a DH DH11-52-81M3 series to serve as a male parent, and enabling the female parent and the male parent to hybridize to obtain a CMS DH09-MP01-78CMS x DH11-52-81M3 combination. The CMS DH09-MP01-78CMS x DH11-52-81M3 combination is named 'Gaoshan 1st' variety. The new variety is subjected to variety comparison testing, variety regional testing and production demonstration in main high-mountain vegetable farming areas including Fengxian County in Baoji, Taibai County and the like of Shanxi Province, proved by the tests, the new variety is remarkable in heterosis, excellent in comprehensive economic characters, mid-mature, resistance to transport, remarkable in disease resistance and yielding ability, high in adaptability and stable in product increasing, and the new variety is rarer and 9.7%-14.1% more in yield as compared with a compared cabbage variety.

Description

technical field

[0001] The invention belongs to the discipline of crop genetics and breeding in agricultural science and technology, and in particular relates to a method for breeding new mid-maturity resistant varieties of cabbage by using CMS and DH lines. Background technique

[0002] Alpine vegetables are the main base for the production and supply of over-summer vegetables, and are the natural vegetable gardens for summer vegetable production in my country. Alpine vegetables are a new type of vegetable production mode developed rapidly in my country in the 1990s. It is the main way to solve the "light summer" supply of vegetables and achieve a balanced market for vegetables every year. The planting of alpine cabbage is developing rapidly in our country, and the area is increasing year by year. The most important characteristic of the cultivated varieties of alpine cabbage is that they require varieties to be resistant to transportation, so that the cabbage from the alpi...
