Description
Technical field
The present invention relates to wheat genetic breeding field more particularly to a kind of SSR molecular marker primers of distant hybridization wheat
And application thereof and screening technique.
Background technique
Wheat scab (FHB) is mainly infected caused by Fusarium graminearum as wheat.It mostly occurs warm damp and hot
Area.Since air pollution bring global warming, the injured area of wheat scab expand year by year nearly ten years, so that
Wheat yield reduces.In China, for wheat as the staple food crop for being only second to rice, cultivated area over the years is that whole nation arable land is total
The 22-30% of the area and 20-27% of the cereal crops gross area is distributed across national each province (city, area).Wheat scab is at me
The state middle and lower reach of Yangtze River and south China Winter Wheat Area and eastern part of Northeast spring wheat area are particularly acute, in recent years also even in Yellow River basin and other areas
There is generation.In recent years, wheat scab has the tendency that north area of wheat extension at home, and there is 2/3rds province in China
Head blight, when severe epidemic, injured area is more than 7,000,000 hectares.
Cultivate one of the most effective means that scab resistance kind is current prevention and treatment wheat scab harm.Lead to wheat
There are many factor of head blight occurrence and development.The difference of environment and pathogen can all influence the evaluation result to scab resistance.
Weather short of rain is such as encountered, is possible to will appear false disease resistance using field test.And the period of this method is longer, does not allow
Be easy to do repetitive identified.So with regard to needing other methods to be assisted simultaneously.Toxin identification method just supplements lacking for field test
It falls into.Its result can also give counterevidence the result of field test.
It is easily affected by environment by controlled by multiple genes since wheat scab resistance has typical quantitative character feature, it is early
Phase is difficult to select it from generation to generation.In addition, the economical character of many anti gibberellic disease germplasm is poor, regional adaptability is stronger, benefit
Cultivate that resistant variety is time-consuming and laborious may also cannot get expected result, molecular labeling and its assisted Selection with traditional breeding way
Breeding provides an effective approach for wheat breeding.Using molecular labeling, directly the genotype of strain can be selected
It selects.It can weaken influence of the environmental condition to result significantly.And its period is short, can carry out in after planting a couple of days to seedling
Detection.This will be greatlyd save, and cultivate the manpower wasted in plant, financial resources and material resources.
Using DNA molecular marker technology, the site of its Resistance QTL can be preferably verified, the auxiliary of wheat anti gibberellic disease is carried out
Help selection and use.Using molecular markers for identification, have the characteristics that accurately and rapidly.Pass through the auxiliary of objective trait related molecular marker
Help selection to combine to be returned with the excellent wheat breed of Comprehensive Traits, it is expected to break the bad chain of character, thus cultivate resist it is red
Mildew harvesting high-quality high-yield new variety of wheat.SSR and DArT label have the characteristics that abundant hereditary variation, wheat gene mapping with
Widely applied molecular labeling in association analysis.Wherein, SSR marker is the relatively conservative sequence according to microsatellite both ends in genome
Arrange the special primer of design, PCR amplification is stablized, and detection technique is simple and mature, be more suitable for molecular marker gene positioning and
Assistant breeding selection
But in the prior art, the preferable kind of anti gibberellic disease, economical character are bad.And due to bad gene linkage
Influence, directly with its mixing breed good with yielding ability, it is difficult to obtain ideal anti gibberellic disease simultaneously again high yield, good quality wheat
New varieties.Therefore, the anti-source of new head blight is created, is had very important significance to Wheat Breeding For Scab Resistance tool.Scientists exist
It is screened near isogenic wheat line, but never breakthrough.

The screening technique of the above-mentioned SSR molecular marker primer for being used to identify distant hybridization wheat scab resistance related gene
Include the following steps:
Step 101 determines head blight height sense kind and wheat scab highly resistance kind from wheat distant species；This implementation
The wheat distant species that example uses are 7 kinds of alien addition lines triticale, small 6 kinds of 5 kinds of wheat and little Lai wheat of laying down
(specific name is shown in Table 1).
The step is accomplished in that the identification of (one) above-mentioned each kind wheat scab resistance:
(1) when wheat flower, head blight inoculated identification, 21d after inoculation are carried out using single flower inoculation method, investigation is inoculated with fringe
Sick spikelet number.The disease index of each kind is calculated with EXCEL.The single flower inoculation formulated referring to academy of agricultural sciences of Jiangsu Province is inoculated with grade
The criteria for classifying carries out grade classification；
(2) indoor Toxin identification is carried out to wheat simultaneously, handle wheat seedling using gibberella Raw toxin and calculates root long
The long inhibiting rate of inhibiting rate, bud and cellular damage degree, resistance of the detection different cultivars wheat for gibberella Raw toxin；
(3) identification of single flower inoculation scab resistance and indoor Toxin identification result carry out systematic comparison and correlation between
Statistical analysis.Highly resistance pond is therefrom selected, height feels pond to carry out the invention of next step.
The result shows that being deposited in small wheat type of laying down, triticale type, little Lai wheat type these three interracial anti gibberellic disease rows
In significant difference: the wheat breed of triticale type belongs to resistant variety (R type) substantially, only there is highly resistance and anti-area
Not；The wheat breed of little Lai wheat type belongs to susceptible kind (S type) substantially, only the difference of high sense and sense；And small wheat of laying down
The wheat breed resistance of type is placed in the middle.Illustrate that rye is the preferable anti-source of head blight, group system can be constructed with common wheat for primary
The building of Molecular Markers Linkage Map.As shown in Table 1, wheat breed and the code table of establishment therefrom select this 3 product of B1, B3, B5
Kind composition highly resistance pond, this 3 high sense ponds of kinds composition C1, C5, C6.
