| 摘 要： | 为探讨小麦各主要农艺性状对产量影响的主次关系,运用灰色关联度分析方法,对2008、2009年两年小麦品比试验的结果进行分析。结果表明,产量高的品种其单位面积穗数和千粒重也相应较高,综合抗病性好的品种产量也较高;关联度大小依次为:单位面积穗数>千粒重>穗粒数>扬花期>成熟期>赤霉病>纹枯病>条锈病>白粉病。说明该地区与产量密切的主要农艺性状为单位面积穗数、千粒重、穗粒数。

| Abstract: | To explore the effects of major agronomic traits on the grain yield of winter wheat, the variety comparison trial results of 12 varieties (such as Zhengmai 9023 and Xinong 979) in 2008 and 2009 in the Southern Henan Plain, China were analyzed by using grey correlation analysis method. It is found that the varieties with high yield had high ears per unit area and high 1000-grain weight. The varieties with good comprehensive performance had high grain yield. The grey correlation degrees of different agronomic... |
