| 摘 要： | 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。 |

| Abstract: | Twenty-six waxy maize varieties were determined on RVA profile characteristics, the total starch content, amylopectin content, amylose content and quality traits, and the relationship among RVA profile characteristics and between RVA profile characteristics and main traits were studied. The results showed that significantly positive correlations were observed among peak viscosity(PV), trough viscosity(TV), breakdown(BD) and final viscosity(FV). RVA profile characteristics had no significantly correlation with total starch content, amylopectin content, amylose content. Glutinousness and PV, TV, BD, FV was significantly negatively, Thickness of skin and PV, TV, FV showed significant negative correlation. |
| Keywords: | Waxy maize Starch RVA spectrum Quality character Correlation |
