Description
Technical field
The present invention relates to the technical field of breeding method, more particularly to a kind of open polymerization recurrent selection breeding side
Method.
Background technology
It is well known that the method that China's wheat breeding mainly uses crossbreeding.The essence of crossbreeding is by artificial
The method of emasculation (or gametocide) artificial pollination allows two parents with different excellent genes to carry out sexual hybridization, from its offspring's
It is found in segregating population and selects the individual for combining parents' merit, to be bred as new material more better than parents or new
Kind, is brought together sometimes for multiple excellent genes being scattered in different parent materials, to be also three parents, four
Hybridization between a parent and extremely multiple parents.It, due to once hybridizing the excellent genes that can only be concentrated in two parents
Want to concentrate the excellent genes of more than two parents, it is necessary to do multiple hybridization.It is time-consuming in multi-parent strain crossover process is done, it is difficult
To keep a large-scale hybrid Population, and early stage parent's excellent genes are easily lost.Conventional cross-breeding be it is a kind of only
Once hybridization or two is done to limited hybridization procedures three times.Conventional breeding obtained hybrid generation after Hybridizing plan is completed,
No matter whether these offsprings contain target gene, separation selection can only be all carried out on this basis, except doing new hybridization again
It is outside the plan, new gene can not have been supplemented to progeny material transformed.
The content of the invention
In order to solve the above technical problems, the present invention provides, a kind of genetic background is wide, intergenic complementation effect is strong and can be right
Group persistently improves, the open polymerization recurrent selection breeding method of time and labour saving.
The open polymerization recurrent selection breeding method of one kind of the present invention, comprises the following steps：
1) quality germplasm, is collected：The elite clone collected in numerous breeding materials；
2), planted as core using the short material that loses, planted using open semi-surrounding planting patterns；
3), awarding under natural conditions is carried out in the excellent different types of germ plasm resource of all around planting of core material
Powder and hybridization；
4), fertile plant is marked and recorded, harvests sterile plant mixing after waiting maturations；
5), every 1 generation all adds in different types of material and carries out polymerization samsara；
6), selected fertile plant offspring alternate selection is cultivated, and is screened, stablized excellent in non-irrigated salt garden and non-adverse circumstance garden respectively
Good strain enters production than experiment；
7) salt tolerant that, goes out to evaluation and screening, drought resisting, High-yield Wheat strain, into variety certification program.
Beneficial effects of the present invention are compared with prior art：By above-mentioned setting,
1st, selecting the short material that loses, Variants have obvious fertile and sterile gene, easily distinguish as core material.
Its openr accumulation of gene of planting environment opened；
2nd, it polymerize recurrent selection breeding and takes turns the selection for connecing a wheel with mating by one, makes the frequency of excellent genes in Recurrent population
Rate rises by wheel, and multiple excellent genes restructuring are higher and higher to the probability in a plant.Not only excellent key-gene can obtain
Restructuring and raising, it is often more important that the beneficial minor gene of huge number can also obtain collection neutralization and add up, and fully excavate minor effect
Potential value of the gene in breeding；
3rd, the present invention establishes Recurrent population by the short material that loses, and creates open environment, gene is enable to give full expression to, select
Excellent offspring's single plant is in adverse circumstance and non-adverse circumstance environment alternate selection to promoting effective knot of breeding material resistance and yielding ability
It closes and the cultivation of kind adaptitude and extensive adaptability is of great significance.Pass through alternate selection, yield accommodation
It broadens, yield potentiality increase, the extensive adaptability enhancing of kind, the validity of selection is than conventional method improve；
4th, the plantation that the offspring's Fertile material filtered out in the present invention can be reciprocal, it is extensive to accumulate more minor genes
Continuous genetic recombination is conducive to break intergenic bad linkage relationship, easily forms favourable linkage relationship and create chance；
5th, easy to operate, at low cost it is an advantage of the invention that technical difficulty is low, offspring is easier to accumulation favorable genes, generally
It can stablize to S4 generations, more excellent variation types can be obtained in the short period of time, Method of selecting progeny ensure that resistance to
Salt, drought resisting, the realization of High-yield Wheat breeding objective.
Specific embodiment
With reference to embodiment, the specific embodiment of the present invention is described in further detail.Following embodiment is used for
Illustrate the present invention, but be not limited to the scope of the present invention.
The open polymerization recurrent selection breeding method of one kind of the present invention, comprises the following steps：
1) quality germplasm, the elite clone collected in numerous breeding materials, are collected；
2), planted as core using the short material that loses, planted using open semi-surrounding planting patterns；
3), awarding under natural conditions is carried out in the excellent different types of germ plasm resource of all around planting of core material
Powder and hybridization；
4), fertile plant is marked and recorded, harvests sterile plant mixing after waiting maturations；
5), every 1 generation all adds in different types of material and carries out polymerization samsara；
6), selected fertile plant offspring alternate selection is cultivated, and is screened, stablized excellent in non-irrigated salt garden and non-adverse circumstance garden respectively
Good strain enters production than experiment；
7) salt tolerant that, goes out to evaluation and screening, drought resisting, High-yield Wheat strain, into variety certification program.
The open polymerization recurrent selection breeding method of one kind of the present invention：
1st, selecting the short material that loses, Variants have obvious fertile and sterile gene, easily distinguish as core material.
Its openr accumulation of gene of planting environment opened；
2nd, it polymerize recurrent selection breeding and takes turns the selection for connecing a wheel with mating by one, makes the frequency of excellent genes in Recurrent population
Rate rises by wheel, and multiple excellent genes restructuring are higher and higher to the probability in a plant.Not only excellent key-gene can obtain
Restructuring and raising, it is often more important that the beneficial minor gene of huge number can also obtain collection neutralization and add up, and fully excavate minor effect
Potential value of the gene in breeding；
