Embodiment Construction

[0083] Below in conjunction with specific embodiment the method for haploid breeding of red cabbage sprout of the present invention is described in further detail, and this method comprises the steps:

[0084] 1) Preparation of explants: According to different breeding objectives, the preparation of explants is also different: for conventional new varieties or new hybrid varieties male line selection, select complementary breeding materials that meet the breeding objectives The buds are emasculated and crossed to obtain the first generation of hybrids, and the first generation of hybrids is sown in stages, and the anthers are taken as explants after the bolting and flowering. For the breeding of male sterile lines, that is, the female parent lines of new hybrid varieties, the existing male sterile maintainer lines that meet the breeding objectives are selected and crossed with corresponding complementary breeding materials to obtain the first generation of hybrids. The second ...

Abstract

A method for culturing new variety of Dilsea by the mono-ploid culture includes such step as in vitro culture of the anther of Dilsea to obtain mono-ploid embryoid, regenerative culture, chromosomal amplification, isolated pollination to obtain a series of different genotypic pure lines, comparing them to screen excellent pure line.

Description

technical field [0001] The invention relates to a red cabbage breeding technology, in particular to a haploid breeding method for red cabbage, which is used for rapid breeding of new varieties of red cabbage. Background technique [0002] At present, in the field of red cabbage breeding, the method of strain selection is mainly used to select new pure lines of red cabbage. The strain screening method is to artificially peel and emasculate the complementary breeding materials that meet the breeding objectives to obtain F 1 The first generation is the hybrid generation, and then the F 1 Multi-generation single plant selfing is carried out, and the economic characteristics of the single line materials of each generation are compared, and excellent single plants are selected for the next generation of single plant selfing, so as to breed new red cabbage sprouts that basically meet the requirements. Pure line. Although the strain screening method can breed conventional new var...
