The biotechnological characteristic of the spring wheat samples in Cisbaikalia on presence of a locus Fhb1 to the fusarium resistanse

The problem of wheat breeding for resistance to the Fusarium of head blight is that small number of donors, namely Sumai 3 and its derivatives are widely used at the present stage in the world. Such a narrow genetic base of Fusarium resistance may be too vulnerable to major pathogens. The article shows the genetic mechanisms of transmission to offspring locus Fhb1, besides our study is associated not only with identification, but also the creation of new sources of resistance genotypes as an example of content of locus Fhb1. The value of this selective protection material is effective resistance genes, allowing its use in breeding programs, as a starting material.
