Abstract
The invention discloses a kind of corn breeding methods, include the following steps: S1, select Parents composition parent group, are oriented runoff catchment, opening pollination obtains cross combination seed F1 generation；S2, F1 generation form, fertility and disease resistance selection are carried out in field, the plant containing target chromosome is selected and remain in combination cell identification, continuous selfing in 3 years, third year carry out mutation breeding by pollen tube passage method with 0.05% EMS while continuing roguing selfing, obtain variant；S3, combination cell identification select and remain the dwarfing variant containing target chromosome, continuous selfing in 2 years, and second year carries out test cross while continuing roguing selfing, and next year is to get target seed.The present invention recombinates beneficial gene by breeding technique, to cultivate, coordinate force is high, disease resistance is good and comprehensive performance preferably self-mating system.
Description
Technical field
The present invention relates to field of agricultural cultivation, and in particular to a kind of corn breeding method.
Background technique
Corn is chief crop in world wide.In China, corn is as the first generalized grain crop, in grain security, poultry
There is important strategic position in animal husbandry development and food processing industry.Corn yield is improved, key technology is improved Varieties
Popularization and application and adaptation to local conditions scientific production method.Breeding high-yield, high-quality, more anti-and extensively suitable corn varieties are breedings
The target that field is adhered to for a long time.
Currently, heavier, incubation product occur for existing corn variety generally existing leaf blight, short mosaic disease in planting process
The general situation of kind quality.
Summary of the invention
To solve the above problems, the present invention provides a kind of corn breeding methods, obtain beneficial gene by breeding technique
It must recombinate, to cultivate, coordinate force is high, disease resistance is good and comprehensive performance preferably self-mating system.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of corn breeding method, includes the following steps:
S1, it selects Parents to form parent group, is oriented runoff catchment, opening pollination obtains cross combination seed
F1 generation；
S2, F1 generation form, fertility and disease resistance selection are carried out in field, combination cell identification is selected and remain containing target coloration
The plant of body, continuous selfing in 3 years pass through pollen tube passage method with 0.05% EMS while continuing roguing selfing in third year
Mutation breeding is carried out, variant is obtained；
S3, combination cell identification select and remain the dwarfing variant containing target chromosome, continuous selfing in 2 years, and second year exists
Continue to carry out test cross while roguing selfing, next year is to get target seed.
Further, it needs first to carry out it plasma treatment before the sowing of seed F1 generation in the step S2, it is described cold etc.
The Parent seed of corn variety is is placed in cold plasma processor by gas ions processing, in the processing function of 100~120W
The unionized width carried out 13~17 seconds under rate to corn seed penetrates processing, handles using helium as working media, in vacuum seal closed loop
It is carried out in border.
Further, high-combining ability, precocity, the self-mating system that dehydration is fast, lodging resistance is strong are included at least in the parent group
LH196 and H39-1 and the short life of polygenes are W8-12.
The present invention recombinates beneficial gene by breeding technique, thus cultivated that coordinate force is high, disease resistance is good and
Comprehensive performance preferably self-mating system.
Specific embodiment
In order to which objects and advantages of the present invention are more clearly understood, the present invention is carried out with reference to embodiments further
It is described in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
A kind of corn breeding method of the embodiment of the present invention, includes the following steps:
S1, it selects Parents to form parent group, is oriented runoff catchment, opening pollination obtains cross combination seed
F1 generation；High-combining ability, precocity, the self-mating system LH196 and H39-1 that dehydration is fast, lodging resistance is strong are included at least in the parent group
And the short life of polygenes is W8-12；
S2, the seed F1 generation seed of corn variety is placed in cold plasma processor, in the processing function of 100~120W
The unionized width carried out 13~17 seconds under rate to corn seed penetrates processing, handles using helium as working media, in vacuum seal closed loop
It is carried out in border；After treatment, sowing carry out F1 generation form, fertility and disease resistance selection, combination cell identification choosing in field
Stay the plant containing target chromosome；Continuous selfing in 3 years is carried out, will select that of short stem, disease resistance is strong, Comprehensive Traits are good per generation
Plant carry out that selfing is homozygous, third year while continuing roguing selfing with 0.05% EMS by pollen tube passage method into
Row mutation breeding, obtains variant；
S3, combination cell identification select and remain the dwarfing variant containing target chromosome, continuous selfing in 2 years, and second year exists
Continue to carry out test cross while roguing selfing, next year is to get target seed.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
