摘要： 通过对黑龙江省28个水稻主栽品种的农艺性状及产量构成因素之间的相关性分析，得出株高与穗长、倒三茎长、倒三叶长呈极显著的正相关；在产量构成因素中，穗粒数与理论产量呈极显著的正相关，相关系数为0.535（r0.05=0.374 r0.01=0.478 n=28）；穗粒数与剑叶宽、倒二叶长、倒二宽、倒三叶长、倒三叶宽呈显著或极显著的正相关；叶片的宽度与结实率呈显著或极显著的负相关，与理论产量呈显著或极显著的正相关。

Abstract: through the relativity of agronomic characters of 28 main plant breeds in Heilongjiang province and yield factors, the results showed : plant height is remarked significant positive to panicle length, converse third burl length, converse third leaf length; Among the factors of field, grain number is remarked significant positive to theoretic yield, the correlation coefficient is 0.535（r0.05=0.374 r0.01=0.478 n=28）；grain number is remarked positive or remarked significant positive to blade leaf width, converse second leaf length, converse second leaf width, converse third leaf length, converse third leaf width; leaf width is remarked negative or remarked significant negative to seed-setting rate and remarked positive or remarked significant to theoretic yield.
