摘　　要：利用快速粘度分析仪(RVA)分析了东北地区新近培育的春谷新品种(系)淀粉粘滞性。结果表明,不同品种(系)具有特征性RVA谱,消减值可有效地区分出品种(系)直链淀粉含量(AC)的高低。低AC品种(系)消减值一般较低,中等或高直链淀粉含量品种(系)消减值较高,相近直链淀粉含量品种(系)间食用品质的优劣,可根据消减值和崩解值来判断。RVA谱特性有望作为理化标记在优质谷子育种中发挥重要作用。Rapid Visco Analyzer （RVA） was used to investigate different spring millet varieties （lines）, which was analyzed recently in Northeast China. The results showed that different varieties had distinct RVA stickiness, and the varieties （lines） with low or high amylose content （AC） could be quickly distinguished by the setback. According to the values of breakdown and setback, it could evaluate the superior or starch viscosity of millet varieties with the breakdown value of RVA stickiness of the similar AC was closely related to the del consistency and the millet taste, meanwhile, the setback value was linked to the millet texture. It suggested that the characteristies of RVA stickiness could be used as an important physical and chemical marker on assisted-selecting good quality millet.
