Embodiment Construction

[0085] Below in conjunction with specific embodiment, the method for rapid selection of new radish varieties of the present invention is described in further detail, the method may further comprise the steps:

[0086] 1) Preparation of explants: According to different breeding objectives, there are differences in the preparation of explants: for the breeding of conventional new varieties or new hybrid varieties, choose complementary breeding materials that meet the breeding objectives and strip them. 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 generati...

Abstract

It relates to a method of quickly selecting and breeding new species of radish. In the breeding method, the haploid embryo bodies developed from male gametophyte cells are acquired through culturing anthers of radish in glass. Then haploid embryo bodies are cultured, doubled chromosomes, and pollinated independently, thereby the different genotypic clones are obtained. The field characters of these clones are compared, and the super clone could be screened out as routine new strains or mating parents. The breeding method avoids the insemination process for radish, simplify the isozygoty process of heterozygotes, shorten the breeding process, thereby improve the breeding efficiency.

Description

technical field [0001] The invention relates to a radish breeding technology, in particular to a method for rapidly selecting a new radish variety. Background technique [0002] At present, in the field of radish breeding, the method of strain selection is mainly used to select new pure lines of radish. 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 Carry out self-crossing of multiple generations of single plants, and compare the economic characteristics of the single-line materials of each generation, and select excellent single plants for the next generation of single-plant selfing, so as to breed new pure lines of radish that basically meet the requirements . Although the strain screening method can breed conventional new radish varieties and hybrid combinations with better comprehensi...
