Description
Technical field
The present invention relates to sorghum breeding technique field more particularly to a kind of methods of selection and breeding sorghum homogeneity restorer.
Background technology
What is applied in China's sorghum production is cenospecies.Therefore, initiative new parent system is the premise for cultivating the hybrid strain with high yield.
What is applied in being produced before last century the eighties is that high stalk hybrid sorghum weaves while producing grain using stalk
Frame material etc., with the development and social progress of chemical industry, the purposes of stalk is reduced；Therefore sorghum production turns after the nineties
For the middle stalk the hybrid strain with high yield suitable for manually harvesting；With artificial rise in price, production must mechanization reduce production cost.
In order to adapt to mechanization growth requirement, it is necessary to cultivate parent and its cenospecies of suitable for mechanization of short stem.Therefore, the present invention will train
Parent material of short stem is educated as main breeding objective, and this item work is hybridized to cultivate recovery of short stem with restorer using sterile line
System.
Sorghum hybrid application is three systems, i.e. sterile line, maintainer and restorer, and some maintenance materials are prepared miscellaneous
Kind is handed over to do well, since the cenospecies matched is unable to self-fertility, so may not apply to produce, if this excellent guarantor
Production can be directly applied at recovery-type material by holding the material transformation of type, not only solve the problems, such as fertility in this way, but also solve
Problem of short stem.The present invention cultivates the serial restorer such as lucky R125 of precocious wide adaptability of short stem by the effort of more than ten years.
Invention content
Technical problems based on background technology, the present invention propose a kind of method of selection and breeding sorghum homogeneity restorer.
Technical scheme is as follows：
A kind of method of selection and breeding sorghum homogeneity restorer, includes the following steps：
The first step：First × second, obtains F1, wherein first is female parent, and second is male parent；
Second step：First × F1, and Precocious Strains of short stem is continuously selected to be returned, the BCx that obtains BC1, BC2, BC3 successively ... ..., until
Obtain the backcross progeny BCx alike with former sterile line first character；
Third walks：BCx is selfed and is purified, obtains BCxF successively1、BCxF2、BCxF3... ... BCxFy, until BCxFyCharacter
It is basicly stable；
4th step：BCxFySelfing purifying, obtains the restorer of character stabilization；
In the first step, first is excellent sterile system, second is Elite restorer line.
Preferably, the first is excellent sterile system Ji 1230A, and second is Elite restorer line Ji R105.
Preferably, the restorer of short stem for the stabilization that the present invention obtains is Ji R125, and 100 centimetres of plant height, blade is narrow, plant type
It is good, 110 days breeding times；Seedling green, 26 centimetres of spike length, the red red grain of shell, coordinate force are high.
Preferably, the first can also be excellent maintainer.
Preferably, method of the invention can be by arbitrary sterile line or maintainer transformation at restorer.
The invention has the beneficial effects that：
The present invention is mainly that the narrow characteristic of leaf of short stem of the restoring gene and sterile line of application recovery system carries out artificial hybridization, i.e.,
The hybridizing method selection and breeding Poa linn of short stem of A × R, removes artificial emasculation from, identical as the cytoplasm of sterile line, so being homogeneity
Restorer.And expand resource application range.
The major advantage for the restorer Ji R125 that the present invention formulates out is that plant is short, and plant height is at 100 centimetres hereinafter, matching
The cenospecies height of system is at 120 centimetres hereinafter, the suitable for mechanization of resistance to dense planting of short stem produces.And resource application range is expanded,
It will regenerate and play a role in promoting to sorghum precocity area of China Cultivar replacing.

Specific implementation mode
Embodiment 1：
A kind of method of selection and breeding sorghum homogeneity restorer, includes the following steps：
The first step：First × second, obtains F1, wherein first is female parent, and second is male parent；
Second step：First × F1, and Precocious Strains of short stem is continuously selected to be returned, BC1, BC2, BC3 are obtained successively；BC3 and original infertility
It is that first character is alike；
Third walks：BC3 is selfed and is purified, obtains BC3F successively1、BC3F2、BC3F3、BC3F4；BC3F4Character is basicly stable；
4th step：BC3F4Selfing purifying, obtains the restorer Ji R125 of character stabilization；
The first is excellent sterile system Ji 1230A, and second is Elite restorer line Ji R105.
The restorer of short stem for the stabilization that the present invention obtains is Ji R125, and 100 centimetres of plant height, blade is narrow, and plant type is good, breeding time
110 days；Seedling green, 26 centimetres of spike length, the red red grain of shell, coordinate force are high.
Embodiment 2：
First in embodiment 1 is replaced with into excellent maintainer, remaining method is constant.
Comparative example
The Chinese invention patent CN107517846A of Sorghum Research Institute, Shanxi Academy of Agricultural Sciences's application (is hereinafter referred to as compared
Example) provide it is a kind of using sterile line as the method for recurrent parent selection and breeding A3 restorers.
The difference of the embodiment of the present invention and comparative example：
The selection-breeding method that this method provides and the method for the present invention are more similar, but still have following difference：
First, material therefor is different with the purpose of selection：The present invention's is the restorer restored to A1 and A2 types, comparison
Example is A3 types restorer (A3 type restorers are considerably less, so comparative example uses extensive Crossing system)；Therefore the present invention selects
It is the qualitative selection for having target to select, and comparative example is to be widely separated middle selection after hybridization.
Second is that method is different：In the present invention, be directly returned in first familiar generation and original sterile line, backcross progeny continue with
Original sterile line backcrossing, offspring to be returned and sterile line are alike to be selfed again, selects new extensive similar with sterile line of form
Multiple system.And in comparative example, sterile line hybridizes with A3 restorers, F1 generation selfing, the loose powder strain self cross and selection separated from F2, warp
It crosses multiple self cross and selection and goes out new restorer line；Also it can continue to be selfed and be returned in segregating generation selection loose powder strain and the sterile plant separated
It hands over, then selects new restorer line through inbreeding of more generation.
Third, result difference to get to restorer character be different：What the present invention obtained is to have short and small sterile line
The restorer of form is conducive to solve suitable for mechanization short-stalked variety select permeability；It is asked the other is solving resource and utilizing extensively
It inscribes, such as the cenospecies that the material having is configured to is fine, but does not restore shaky, may not apply to produce, so this kind of
Based material transformation is kept just to solve the problems, such as this at restorer.Therefore, the method for the present invention can be used arbitrary sterile line or
Person's maintainer transformation is at restorer.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
