本文利用典型相关分析研究了水稻株型、穗部性状及产量因素三组性状间的关系。结果表明,该三组性状间的关系十分密切,选育具有壮杆和较大剑叶面积的株型将有助于克服产量因素之间相互制约的矛盾。 In this paper, canonical correlation analysis was used to study the relationship between plant type, panicle traits and yield components in rice. The results showed that the relationships among these three traits were very close. Breeding of plant lines with strong stalks and larger leaf area would help to overcome the contradiction between the yield factors.
