Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of direct directional transfer of the standard strong dominant combination formulated by chemical killing method into non-1B / 1R wheat male sterile three-line qualified strong dominant combination, which can effectively induce male sterility by chemical andricidal The organic combination with the three-line method (Cytoplasm-nucleus Male Sterility, abbreviated as CMS) has solved some difficult problems in the current research and production of male sterility of myxoids, such as the single male sterile line produced Ploidy, low degree of recovery, large variation in recovery, etc., in order to breed an excellent three-line combination that can be directly used in production

Embodiment Construction

[0061] The present invention adopts rigorous and scientific chromosome engineering technology and cytogenetic analysis technology to transfer the 1B chromosome of the sterile gene (rfv1) of the glutinous sterile line in wheat to replace the 1B chromosome of the female parent in the strong combination of CHA (In the case of not carrying the rfv1 gene); the 1B chromosome carrying the restorer gene (Rfv1) of the sticky sterile line is targeted to replace the 1B chromosome of the male parent in the strong combination of CHA (in the case of not carrying the Rfv1 gene) ). And through chromosomal marker selection and targeted continuous replacement backcross, the other genetic background of the recipient of the replaced parent (CHA parent) is kept basically unchanged, and the same sterile line, maintainer line and restorer line as the parent of the same combination of CHA are bred , So as to achieve the three-line matching, and finally the three-line superior combination with the same co...

Abstract

A method for culturing the male sterile wheat by transferring from the chenmical male-sterilizing combination to the three-line combination features that the chromasone transfer technique is used to transfer the chromosen 1B with sterile gene rfv1 in SP4 or other parents to the female parent of chemical male-sterilizing combination for selectively culturing the male sterile maintenance line and sterile line of excellent glutinous non-1B / 1R wheat, and the chromosome 1B with recovery gene Rfv1 in the excellent recovery line of male sterile line for glutinous wheat is transferred the male parent of chemical male-sterilizing combination to selectively culture excellent recovery line.

Description

Technical field [0001] The invention relates to the field of utilization of wheat heterosis, and relates to a method for transforming a wheat chemical-killing combination into a three-line combination. Background technique [0002] Heterosis is a common phenomenon in the biological world. Using heterosis to increase crop yield is one of the important achievements in the field of modern genetics. The use of wheat heterosis, since Wilson and Ross discovered in 1962 that male sterility (called T-type sterile line) with the cytoplasm of T.Timopheevi wheat (called T-type sterile line) and its fertility restoration system, countries around the world have actively Carried out the use of T-type male sterile line for wheat heterosis utilization research. However, with the practical application of T-type male sterile lines, it has been found that the shortcomings of T-type male sterile lines such as shrinking seeds and narrow recovery sources have become the biggest obstacle to the further...
