Disclosed is a method for cultivating scab-resistant and high-yield wheat in wheat regions, 5 in particular in the Huanghuai wheat region, based on polygene polymerization. In the method, the scab-resistant intermediate material NMASOZO with excellent comprehensive agronomic characters carrying a plurality of scab-resistant genes is used as the resistance source, and the large-area varieties and excellent strains in wheat region are used as the background parents. Using molecular markers linked markers LJJ-1 of th1, linked markers LJJ-2 and LJJ-3 of 10 th2, and linked markers LJJ-4 and LJJ-5 of th5 assisted selection combined with identification techniques for resistance to expansion and infection of scab, the semi-winter breeding materials or lines with good adaptability and comprehensive characters were created, which provided a material source for cultivating high-yield wheat varieties with scab resistance suitable for planting in the wheat area.
