摘要
以64份粳稻品种为试材,分析了品种株型性状的差异,并对品种进行主成份和聚类分析,结果表明,冠层因子、高度因子、穗长因子、叶宽因子、角度因子是影响粳稻品种株型表现的主要因素。64个粳稻品种可明确分为6个类群,不同类群具有不同的株型特点,类群间存在着较大的距离,可作为品种亲本选择的重要依据。
The difference and cluster analysis were analysed by using the 64 rice varieties and the results indicated that the major factor to affect stalks were canopy factor,height factor,panicle length factor factor,leaf width factor and angle factor.The 64 rice varieties can be divided into 6 groups,they had different characteristic on plant type and can be the major foundation for selecting parent.
