Abstract: In order to get the high yield and eurytopic wheat variety, and meet the demands for weak gluten wheat industry development in the south wheat area, the new variety ‘Yangmai 20’ was breed by the comprehensive breeding technology route. In different annual test, the variety showed excellent comprehensive characters, and middle resistance to Powdery mildew and Fusarium head blight, wheat sharp eyespot happened lightly, and higher yield increased range from 3.4% to 12.4% compared with the wheat variety ‘Yangmai 158’, and main quality characters accorded with national weak gluten wheat standard. To a large extent this variety breeding and popularization has solved the problems of high yield and eurytopic wheat in the south wheat area, will further promote the wheat production level and relevant industries.
