| 摘 要： | 在进行糯玉米品种比较试验中,利用关联分析法对糯玉米的鲜穗产量与其相关性状进行了关联性分析,糯玉米鲜穗产量与其相关性状的关联度大小顺序依次为穗位高>株高>生育期>穗长>行粒数>棒三叶叶面积>穗粗>穗行数。明确了各相关性状对产量影响的主次关系,棒三叶叶面积与鲜穗产量的关联度大于穗粗、穗行数与鲜穗产量的关联度。

| Abstract: | Comparison of main traits of waxy maize varieties had been conducted.The correlation between fresh ear yields and relative agronomic traits were analyzed by method of grey correlative degree analysis.The result showed that the values of the correlation degree between fresh-cob yield and main agronomic traits among different varieties were sequenced as follows: ear position height > plant height > growth period > ear length > kernel numbers per row > three leaves area near the ear > ear wide > row number of seeds per ear.This sequence indicated the effects of different traits on yields. |
