以9个不同基因型啤酒大麦品种（系）为供试材料，比较了籽粒灌浆特性及产量性状等指标。结果表明：不同基因型啤酒大麦品种（系）籽粒灌浆过程均呈“S”型曲线变化，开花后天数与千粒重的关系均符合Logistic方程，籽粒灌浆速率变化均呈“慢—快—慢”规律；高秆、旗叶宽大的品种（系）粒重增加时间较早；分蘖能力强或旗叶宽大的品种（系）灌浆速率峰值显现较早，且为单峰，其他品种（系）则为双峰；株高、分蘖能力、旗叶适中的品种（系）保持较高灌浆速率的持续时间较长；在各灌浆特征参数中，最大灌浆速率（ Rmax ）与产量的灰色关联度最大，平均灌浆速率（R）与千粒重的灰色关联度最大，起始生长势（C0）对前期贡献率的灰色关联度最大。旗叶宽大、分蘖能力和抗旱性较强的品种（系）穗长和穗粒重最大，穗粒数最多，具有一定的产量优势，可作为育种选择目标。0110－16和甘啤7号品种（系）单位面积产量较高，可在生产上推广应用。

Mon-factor Randomized Complete Block Design (RCBD ) experiment was conducted to analyze the index-es including grain-filling and yield characteristics of nine malting barley cultivars .Results indicated that the grain-filling processes in malting barley cultivars of different genotypes exhibited changes in an S-like shape ,relationship of theirs be-tween days after flowering and thousand grain weight all best fitted the Logistic Growth Equation (LGE) ,and the varia-tions of their grain-filling rates were all in slow-fast-slow trend .The gain of grain weight happened earlier in cultivars with tall plant and wide flag leaf than others .Filling rate reached its only peak earlier in cultivars with strong tillering ability and wide flag leaf than other cultivars that owned two peak rates .The cultivars with moderate plant height ,tillering abili-ty ,and flag leaf ,retained a high filling rate for a relative long time .Among parameters related to filling characteristics , the grey correlation degrees between Rmax and yield ,between R and thousand grain weight ,and between C0 contribution and earlier growing stage ,remained the highest .Ear length ,grain weight per ear ,and seeds per ear in cultivars with wide flag leaf ,high tillering ability ,and strong drought resistance ,were found to reach their best levels ,which might be advantageous in production and useful for breeding .The yields per unit area were high in 0110-16 and Ganpi 7 which could be extended for production .
