Sažetak
The primary objective of the winter wheat breeding program at the Agricultural Institute Osijek is to enhance the profitability of wheat production by developing and releasing improved wheat varieties. This means selection for early maturity, lodging resistance, disease resistance, freeze tolerance, along with high yield and good quality. Diseases can be the most limiting factor in expression of genetic potential. The most important wheat diseases are powdery mildew, leaf rust, septoria diseases and fusarium head blight. Traditionally, breeders have introduced resistance traits into wheat by crossing commercial plants with other wheat varieties that are able to fend off a pathogen, which is time-consuming process. Germplasm from Agricultural Institute Osijek was screened for Type I (incidence), Type II (spread in the spike), Type III (DON resistance) resistance to fusarium head blight, and leaf and stem rust seedling resistance using appropriated published methodologies. Combining various types of resistance to different diseases is expected to generate lines with higher levels of resistance and more effective resistance under high inoculum loads.
