以26个不同糯玉米品种为试验材料,测定其RVA谱特征值以及总淀粉含量、支链淀粉含量、直链淀粉含量等淀粉品质性状及品尝品质性状,分析不同糯玉米品种的RVA谱特征值间及其与主要品质性状间的相关性。结果表明,RVA谱特征值间的峰值黏度与谷值黏度、崩解值、终值黏度呈极显著正相关;谷值黏度、崩解值与终值黏度两两间呈极显著正相关;总淀粉含量、支链淀粉含量、直链淀粉含量与RVA谱特征值均未达到显著相关;糯性与峰值黏度、谷值黏度、崩解值、终值黏度呈显著负相关;果皮厚薄与峰值黏度、谷值黏度、终值黏度呈极显著负相关。
Twenty-six different waxy maize cultivars were used as experimental materials to determine their RVA profiles and their starch content, amylopectin content, amylose content and other quality traits. The RVA profiles of different waxy maize varieties were analyzed. Between and its correlation with the main quality traits. The results showed that there was a significant positive correlation between the peak viscosity and the valley viscosity, the breakdown value and the final viscosity of the RVA profiles. The valley viscosity, the breakdown value and the final viscosity had a significant positive correlation Starch content, amylopectin content and amylose content had no significant correlation with RVA profiles. Waxiness was negatively correlated with peak viscosity, valley viscosity, disintegration value and final viscosity. Peel thickness and peak viscosity , Valley viscosity, final viscosity showed a very significant negative correlation.
