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、A7-303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。
In order to provide suitable parent materials α-amylase activity of 13 cuhivars were analyzed after for malting barley, protein content and β-amylase and 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 ＇humai 16＇ than those in others （P〈0.05）, then was A7-30 which was followed by ＇Jin barley2＇, those in 09-189, ＇Zhu3＇, ＇Gangl＇ and ＇Han 98-58＇ were statistically lower than above cuhivars （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 cuhivals （P〈0.05）. ＇Jin barley 2＇, 09-189 and A7-30 were the suitable parent materials for breeding malting barley since the higherfl-amylase activity and than 12.5% grain protein content presented.
