在北京利用早熟小麦品种与抗白粉病而晚熟的小麦种质 Ｆｒ８１８ 杂交，获得了一批抗白粉病的早熟品系。这些品系株高８０～９０ｃｍ ， 千粒重４２～５１ｇ， 其中有３ 个品系兼抗条锈病， １ 个品系兼抗条锈病和叶锈病。它们均可供生产试种和育种用作亲本。 In Beijing, early maturing wheat lines resistant to powdery mildew were obtained by crossing early wheat varieties Fr818 with early maturing wheat varieties and resistant to powdery mildew. The strains were 80-90 cm in height and 42-51 g in 1000-grain weight, of which 3 strains were resistant to stripe rust and 1 strain was resistant to stripe rust and leaf rust. They are both available for production test and breeding as parents.
