Embodiment 1

[0029] Example 1 Breeding of mustard mustard cytoplasmic male sterile line

[0030] One, the mustard type rape cytoplasmic male sterile line 6-102A used in the present invention is carried out genetic classification, and its steps are as follows:

[0031] 1. Determination of recovery relationship:

[0032] (1) The correct genetic classification of the mustard-type cytoplasmic male sterile line was carried out through the determination of the restoration relationship, and the material numbered 6-102A was determined to be a new cytoplasmic male sterile cytoplasmic type.

[0033] (2) Through the determination of the recovery relationship (see Fu Tingdong, "Breeding and Utilization of Hybrid Rapeseed", Hubei Science and Technology Press, the method introduced in 2000 edition), select 39 Brassica napus and Brassica napus varieties or lines respectively Testcross with pol CMS; ogu CMS, tour CMS, nap CMS, 6-102A, and the results of the restoration relationship are shown in Table 1. ...

Abstract

The present invention relates to a method for selecting and breeding tuber muslard cytoplasmic male sterile line. It is characterized by that it uses natural mustard rape cytoplasmic male sterile line 6-102A as female parent, uses high-quality tuber mustard 6-170 as maintainer line, utilizes continuous backcross and molecular making auxiliary selection to obtain genetic stable tuber mustard cytoplasmic male sterile line CMS 6-170, breeding said sterile line so as to obtain the tuber mustard cytoplasmic male sterile line for production application.

Description

technical field [0001] The invention belongs to the technical field of cruciferous vegetable breeding, and in particular relates to a method for selecting and propagating a new cytoplasmic male sterile line of pickled mustard. Background technique [0002] Cytoplasmic male sterility (abbreviated as CMS, the same below) is the most important way of heterosis in rapeseed. At present, there are many types of cytoplasmic male sterility reported at home and abroad. According to their different sources, they can be divided into two categories: heterologous cytoplasmic male sterility and homologous cytoplasmic male sterility: in heterologous CMS, the most useful and has begun There are ogu CMS, kosena CMS and tour CMS for commercial breeding; among the homologous CMS, the one with commercial value is mainly Polima cytoplasmic male sterile line (Pol CMS). Pol CMS is the world's first practical rapeseed cytoplasmic male sterile line discovered by Professor Fu Tingdong of Huazhong Ag...
