摘 要 ：用粘度速测仪(RVA)测定了72个水稻品种的淀粉粘滞性谱(RVA谱)，发现不同亚种之间RVA谱的特征存在明显差异。表观直链淀粉含量(Apparent Amylose Content AAC)相似的水稻品种，崩解值大小依次为爪哇稻>粳稻>粕稻，而消减值呈相反趋势。在43个釉稻品种中，AAC与RVA谱的热浆粘度、冷胶粘度、消减值和回复值均呈极显著正相关，相

Abstract:Using Rapid Visco-Analyzer(RVA)，the starch viscosity profiles(RVA profile) of 72 cultivars or lines within 3 rice subspecies were analyzed. Significant difference of RVA profiles was found among rice subspecies. The breakdown of rice varieties with similar AAC continually decreased from javanica to
