| 摘 要： | 本文通过6个水稻品种7个性状指标的典型相关分析，结果表明：水稻产量构成因素与植株特性的第一和第二典型相关系数达极显著水平，分别为0．834466和0．590734，占总相关的98．99％；单株产量与植株特性和产量构成因素的典型相关系数也达极显著水平，分别为0．975675和0．843063。从分析结果可得出在这些性状中起主要作用的性状指标有株穗数（X7）和干物重（X3）。

| Abstract: | This article presents the result of canonical correlation analysis between 7 characteristics of 6 paddy rice cultivars It was highly significant correlation between the yield components and the plant characteristics' first two canonical correlation coefficients,0 834466 and 0 590734, together up to 98 99% of the total correlation value It was also highly significant correlation between the single plant's yield and the plant characteristics as well as the yield components with 0 975675 and 0 843063 as their canonical correlation coefficients respectively.The analysis showed that the most important plant characteristics on affecting a single plant's yield were spikelet number( X 7) of plant and the plant's weight( X 3) of dry substance among these characteristics. |
