摘要：

为选育啤酒大麦优良品种（系）提供适宜的亲本材料，经生态适应性、生产实用性选育后，对13种啤酒大麦品（系）种蛋白质含量、β-淀粉酶、α-淀粉酶活性进行检测分析，结果表明：不同大麦品种麦芽β-淀粉酶活性差异较大，‘沪麦16’的β-淀粉酶活性显著高于其他品种(P<0.05)，其次为A7-30、‘晋大麦（啤）2号’和09-189次之，‘驻3’、‘港啤1号’和‘邯98-58’的β-淀粉酶活性显著低于以上品种；‘晋大麦（啤）2号’、‘临啤3号’、W-03、‘驻9125’的籽粒蛋白均低于12%；09-189、A7-30、‘京984’及‘盐95137’的蛋白质含量在12%~12.5%，均显著低于其他5个品种(P<0.05)。‘晋大麦（啤）2号’、09-189、A7-30 3个品种（系），其β-淀粉酶活性较高，且蛋白质含量低于12.5%，可作为选育优良啤酒大麦的材料。

Abstract:

In order to provide suitable parent materials for malting barley, protein content andβandαamylase activity of 13cultivars were analyzed after they were subjected to selective breeding of ecological adaptability and production applicability. The results showed that β-amylase activity varied where it was significantly higher in hu mail 16 than those in others (P<0.05), then was A7-30 which was followed by jin barley2, those in 09-189, zhu3, gang1 and Han 98-58 were statistically lower than above cultivars (P<0.05); grain protein content in Jin barely 2, Lin 3,W-03 and Zhu 9125 were less than 12%; those in 09-189, A7-30, Jing 984 and Yan 95137 were between 12% and 12.5% which were higher than the rest 5 cultivals (P<0.05). Jin barley 2, 09-189 and A7-30 were the suitable parent materials for breeding malting barley since the higher β-amylase activity and than 12.5% grain protein content presented.In order to provide suitable parent materials for malting barley, protein content andβandαamylase activity of 13cultivars were analyzed after they were subjected to selective breeding of ecological adaptability and production applicability.
