中文摘要：对12个水稻品种生理成熟期的产量和叶型特征进行典型相关分析,结果表明:产量与叶型特征各性状的典型相关系数均达显著或极显著水平。剑叶宽、短、直和叶基夹角小;倒二叶厚、直、叶鞘长;倒三叶长、直、窄、厚、叶鞘较短和叶基夹角较大的株型对产量的提高有利。

外文摘要：This paper presents the result of canonical correlation analysis between leaf characters and yield of 12 paddy rice cultivars measured during the physiological maturing stage. The results are as follows ： It is significant or highly significant correlation between leaf characters and yield. The yield is higher than the plant type with wider, shorter and erect leaves with smaller base angle, longer and thicker straight second backward leaf with longer sheath, longer and narrower and thicker straight third backward leaf with larger base angle as well as with shorter sheath.
