利用北方冬麦区联合区试及北京、天津、山西等省市主持的中肥组区试和生产试验资料，研究了冬丰１号小麦的高产性、稳产性及广泛适应性。结果表明，冬丰１号在中肥条件下一般单产３５０～４００ｋｇ／亩，具有４５０ｋｇ／亩的高产潜力，产量的稳定性回归系数ｂ值小于１，Ｓｄ２值低，高稳指数高。产量构成三要素稳定性好。抗寒、抗旱、抗锈病及白粉病，营养品质和加工品质优良，适应北方冬麦区大面积推广。 This paper studied the yield, stability and broad adaptability of Dongfeng 1 wheat by using the trial of the joint trial of the northern winter wheat area and the trials and production trials conducted by the provinces of Beijing, Tianjin and Shanxi. The results showed that Dongfeng No.1 generally yields 350-400 kg / acre under the medium fertilizer condition and has a high yield potential of 450 kg / acre. The regression coefficient b of the yield is less than 1, the Sd2 value is low and the high stability index is high. The three elements of production constitute a good stability. Cold, drought, rust resistance and powdery mildew, good nutritional quality and processing quality, to adapt to the large area of ​​winter wheat area to promote.
