| 摘 要： | 目的]为优质小麦的品种选育、栽培调控及加工提供参考依据。方法]将不同HMW-GS类型的小麦品种在宁夏不同纬度地区种植,收获储存30 d后进行品质分析。结果]宁春4号、宁春43号、宁J210、1188-1的HMW-GS评分较高,宁春35号的较低。小麦各品质指标与HMW-GS评分的相关程度由大到小依次为:湿面筋含量>蛋白质含量>硬度>沉降值,前3个指标与HMW-GS评分呈正相关,沉降值与HMW-GS评分呈负相关。在不同纬度条件下,宁春35号的各项品质指标较稳定,宁春4号和1188-1次之。随着纬度的升高,供试小麦品种的主要品质指标呈上升趋势。结论]HMW-GS评分与小麦营养品质密切相关,HMW-GS评分高的品种,其品质指标受生态环境条件的影响较小。

| Abstract: | Objective] The study was to provide a reference for breeding,cultivation and regulation and processing of wheat with high quality.Method] Different HMW-GS wheat varieties were planted in regions with different latitudes in Ningxia.After harvest,they were stored for 30 d to analyze their quality.Result] The HMW-GS scores of Ningchun 4,Ningchun 43,Ning J210,1188-1 were higher and that of Ningchun 35 was lower.The correlative degree between wheat quality indices and HMW-GS score from big to small was wet gluten content > protein content > hardness > sedimentation value.Three former indices had a positive correlation with HMW-GS score and sedimentation value had a negative correlation with HMW-GS score.Under different latitude conditions,the quality indices of Ningchun 35 was more stable and that of Ningchun 4 and 1188-1 were secondary.The main quality indices of wheat varieties had an increasing tread with the rise of latitude.Conclusion] HMW-GS score was closely related with nutritional quality of wheat.The quality indices of variety with high HMW-GS score were influenced relatively less by ecological condition. |
