摘　　要：本研究系统分析了适合辽宁地区的水稻品种(系)资源各类品质性状间的相关性,并应用因子分析和典型相关分析方法研究了各类品质性状的关系。结果表明:多个RVA谱特征值之间相关性显著,直链淀粉含量和食味值与垩白性状呈负相关,食味值与蛋白质含量呈负相关;多个RVA谱特征值与垩白性状、直链淀粉含量和食味值之间存在显著相关性。因子分析表明RVA谱特征值可分为过程因子(热浆黏度、崩解值、冷胶黏度、回复值、峰值时间)和变性因子(峰值黏度和糊化温度),品质性状可分为垩白因子、碾米因子和食味因子,并且过程因子和垩白因子变异贡献率最大。RVA谱特征值与其他品质性状典型相关分析中共检测到3组显著的典型相关变量,其中以冷胶黏度与其他品质性状关系最为密切,其次是热浆黏度、崩解值和回复值;品质性状中垩白性状与RVA谱特征值相关性最高,其次是直链淀粉含量,此外蛋白质含量和食味值与RVA谱特征值也存在显著相关性。本研究结果进一步明确了辽宁粳稻品种(系)资源RVA谱特征值与稻米品质的关系以及其在稻米品质评价中的重要作用,为辽宁地区水稻优质育种提供了理论依据。Abstact The correlation of several kinds of quality traits were analyzed with rice varieties suitable for Liaoning area using factor analysis and canonical correlation analysis. The main factor effects of all kinds of quality characters and the relationship between the starch RVA profile characteristics and other quality traits were studied. The results showed that the multiple RVA profile characteristics were significantly correlated. Amylose content and taste valuewas correlated with chalkiness negatively. The taste value was negatively correlated with protein content. Multiple RVA profile characteristics had significant correlation with some quality traits such as chalkiness, amylose content and taste value. Factor analysis showed that the RVA profile characteristics could be divided into process factor（hot paste viscosity, breakdown, cool paste viscosity, setback, peak time） and denaturation factor（peak viscosity and pasting temperature）. Quality traits could be divided into chalkiness factor, milling factor and taste factor. Process factor and chalkiness factor variation contributed most. Three typical related variables were detected in canonical correlation analysis between RVA profile characteristics and other quality traits. The relationship between the cool paste viscosity and other quality traits most closely, followed by hot viscosity, breakdown and setback. The correlation between the quality traits and the RVA profile characteristics were highest, followed by amylose content. In addition, protein content and taste value had a significant correlation with RVA profile characteristics. The results of this study further clarify the relationship between RVA profile characteristics and quality of japonica rice in Liaoning province and its important role in the evaluation of rice quality, which provided theoretical basis for the quality breeding of rice in this region.
