我国杂交小麦育种获突破性进展。西北农业大学科研人员历时15年培育成功的强优势K型杂交春小麦组合“901”,平均亩产600公斤以上,标志着我国杂交小麦研究居世界先进水平。 K型杂交春小麦“901”在我国西北春麦区明显地表现出多方面的栽种优势。一是增产潜力大,“901”平均亩产728.3公斤,比当地主栽品种增产15.6％;二是抗性强,“901”株高87厘米,比当地主栽品种矮5～7厘米,茎秆坚韧,弹性好,亩产600～800公斤水平下不倒伏,3年示范未发生条锈、黄矮、叶枯等小麦易发病害并抗干热风;三是品质优良,籽粒白色,角质透明, Breeding of hybrid wheat in China has been a breakthrough. Northwest Agricultural University researchers lasted 15 years to cultivate successful strong K-type hybrid spring wheat combination “901”, the average yield of more than 600 kg, indicating that China’s hybrid wheat research in the world’s advanced level. The K-type hybrid spring wheat “901” obviously showed many advantages in planting in northwest China’s spring wheat area. First, the yield potential is large. The average yield per mu of “901” is 728.3 kg, 15.6% more than that of the main cultivars. The other is strong resistance. The height of “901” plant is 87 cm, shorter than the local cultivars by 5 to 7 cm. Stalk tough, good elasticity, per mu 600-800 kg level does not lodging, three years of the model does not occur stripe rust, yellow dwarf, leaf blight and other wheat susceptible to disease and anti-hot air; Third, good quality, white kernel, horny transparent ,
