Miros' S. Genetic determination of the winter wheat resistance to Fusarium Head Blight(Fusarium graminearum Schwabe) in the south of Ukraine

Genetic determination of plant resistance to disease. Establishment of genetic determination of winter wheat resistance to Fusarium head blight and search for phenotypic markers of resistance. Hybridological analysis, electrophoretic investigation in PAAG. The number of resistance genes and interaction between they, biochemical markers for estimate resistance level was defined. For the first time it has been studied gen-enzyme determination of resistance to F. graminearum of wheat lines, which represent the cultivars in the South of Ukraine. Functional state of gen-enzyme system of these lines have been estimated. The collection of resistance to Fusarium Head blight wheat genotype was created. It was created ten winter wheat lines and was studied genetic basic of its resistance to Fusarium. Wheat breading
