| Abstract: | Stem rust, leaf rust and powdery mildew are major diseases and ban attack objects of wheat resistance breding in Northeatern China area. According to current situation of resistance of wheat cultivars to stem rust, leafleaf rust and pwwdery mildew, problem in utilization of resistant sources in wheat beding were analysed, andstrategies of breeding for durability of disease resistance were discussed. Put forward 5-step method, including utilizationof diversified 2nd-line resistance, additive generation and rolling backcross, transfer of germ plasm of high yield andgood quality, pramiding of multiple genes and combination of resistance for several several diseases. It mightaccelerate utilization of 2nd-line resistance, promote diversify of resistant sources and raise durable resistance of cultivars. |
