Embodiment 1

[0029] Example 1 Breeding of Cytoplasmic Male Sterile Line of Brassica juncea

[0030] One, the cytoplasmic male sterile line 6-102A of mustard type rape 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.

[0034] Varie...

Abstract

A process for selectively culturing the cytoplasmic male sterile line CMS6-150 of covering mustard includes such steps as continuous backcrossings between the natural mustard-type rape's cytoplasmic male sterile line 6-102A as female parent and the maintainer-line covering mustard 6-150 as male parent while molecular marker aided selecting to obtain the cytoplasmic male sterile line and maintainer line of covering mustard, and reproducing said cytoplasmic male sterile line.

Description

technical field [0001] The invention belongs to the technical field of cruciferous vegetable breeding, and in particular relates to a new breeding method for a cytoplasmic male sterile line of mustard mustard. Background technique [0002] Cytoplasmic male sterility (CMS for short, the same below) is the most important way to utilize 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 homologous CMSs, the most commercially valuable is the Polima cytoplasmic male sterile line (abbreviated as Pol CMS, the same below). Pol CMS is the first practical rapeseed pol CMS line in the world discovered b...
