本文对当前推广１６个水稻品种进行性状相关分析，阐述了株高、剑叶角度、长度、宽度、面积；倒２叶角度、长度、宽度、面积，倒３叶角度、长度、宽度、面积与产量关系。从而提出要想提高产量，不仅要考虑水稻的产量构成因素，而且要考虑水稻的株型。为吉林省水稻高产栽培和水稻育种提供科学依据。
In this paper, trait correlation analysis of 16 rice cultivars is carried out, and the plant height, the angle, length, width and area of the flag leaf are described. The angle, length, width, area, Yield relationship. Thus proposed to increase production, not only to consider the composition of rice yield factors, but also to consider the plant type of rice. Provide scientific basis for high-yielding rice cultivation and rice breeding in Jilin Province.
