摘　　要：本文以不同品质类型的小麦品种为试材,分析比较不同品种的产量潜力及其产量动态变化规律。结果表明:中筋品种克97-831产量显著高于强筋和弱筋类型,分别较克旱19号、新克旱号、克90-99、龙麦26高出21.6%,20.66%,18.7%,30.5%.产量构成因子中以不同品种产量构成因子对产量的作用关系不同。绿色旗叶面积始花期达到顶峰后,下降陡度小,灌浆速率大,且持续时间长,利于有效同化产物的转化。收获指数对籽粒增重为正效应。Wheat with different quality types was used to analyze the output potential and the dynamic change of output. The results showed that the yield of medium gluten wheat Ke 97 - 831 is obviously higher than that of the strong gluten and weak gluten wheat and its yield was higher than that of Kehan 19, Xinkehan, Ke 90 -99 and Longmai 26 by 21.6%, 20.66%, 18.7%, and 30.5%. The yield components of different kinds of wheat had different effect on its yield. When the flag leaf area reaches its peak in the beginning period, slighter drop steepness, bigger grain filling rates and longer duration is good for the transformation of effective assimilation. The correlation of the harvest index with the weight increment is positive.
