| 摘 要： | 为了解近年北方冬麦区育成优质小麦品种的品质状况，两年两点统一种植52份优质品种(系)及6份国外代表性品种，测定其磨粉品质、和面仪和混合实验仪特性、淀粉糊化特性及面条品质，并利用5个基因特异性标记分析基因型分布及其对品质性状的影响。结果表明，大部分品种为硬质、中强筋类型，品种间出粉率、面粉a*值、b*值、黄色素含量、PPO活性、和面仪参数、混合实验仪形成时间和稳定时间差异较大。和面仪8 min带宽和混合实验仪稳定时间可作为预测面条品质的重要指标，可分别解释面条总分变异33.3%和34.4%。Ppo-A1a和Ppo-A1b频率为41.4%和58.6%，两种基因型间PPO活性差异显著(P<0.05)；Ppo-D1a和Ppo-D1b频率为51.7%和48.3%，但PPO活性差异不显著；Psy-A1a和Psy-A1b频率为81.0%和19.0%，两种基因型间黄色素含量差异显著(P<0.05)；1BL/1RS易位和非易位品种频率为13.8%和86.2%，两种基因型间面粉L*值、黄色素含量、和面仪衰落势与8 min带宽、混合实验仪稳定时间等差异显著(P<0.05)。面条品质较好的品种包括Sunzell、石优17、郑麦366、中麦 895、周麦 26、CA1004和石4185。本研究明确了58份小麦品种(系)的品质特征和基因型分布，为优质小麦新品种选育和推广提供了重要信息。

| Abstract: | Fifty-two cultivars and lines from Northern China Winter Wheat Regions, and six cultivars from Australia and America were planted in two locations in two years to evaluate their milling quality, Mixograph and Mixolab parameters, pasting properties and noodle quality. Five gene-specific markers were used to test their effectson quality traits. The results indicated that most of the tested cultivars were featured with hard grain and strong gluten. Large variations of flour yield, flour a* value, b* value, yellow pigment content, PPO activity, Mixograph parameters, Mixolab parameters such as development time and stability were observed. The Mixograph parameter width at 8 min and Mixolab parameter stability were important for predicting noodle quality, accounting for 36.9% and 28.0% of the variation for noodle total score, respectively. Ppo-A1a and Ppo-A1b genotypes had the frequency of 41.4% and 58.6%, respectively, with significant difference in (P<0.05) PPO activity. The frequency of Ppo-D1a and Ppo-D1b was 51.7% and 48.3%, respectively, and there was no significant difference in PPO activity between two genotypes. The frequency ofPsy-A1a and Psy-A1b was 81.0% and 19.0%, respectively, and the yellow pigment contents of two genotypes were significantly different (P<0.05). The 1BL/1RSand non-1BL/1RScultivars had the frequency of 13.8% and 86.2%, respectively, with significant difference (P<0.05) in flour L* value, yellow pigment content, Mixgraph parameters such as right of peak slope and width at 8 min, and Mixolab parameter stability. Four cultivars including Zhoumai 26, Zhongmai 895, Sunzell, and CA1004 showed excellent noodle quality. This study provides important informations for wheat breeding and cultivar extension. |
