In recent years, frequent changes in the production of winter wheat, blind tune, the phenomenon of cross-introduction is on the rise, the introduction of southern varieties in the northern region, dryland wheat varieties introduced water, barren plots introduced varieties resistant to tolerance, and focus on yield Neglect of resistance and other issues is more prominent, improper selection and disaster reduction occurred more often. In order to solve the problem of wheat selection on the wrong way, we should highlight the regional characteristics, optimize the layout according to local conditions according to climate, soil, ground force, planting system, yield level and disease occurrence,
