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 major agronomic traits of wheat on the yield of primary and secondary relationship, this gray relational analysis method, the two years of 2008, 2009 Wheat Varieties Test results of the analysis. The results show that the correlation in the order: panicles > grain weight > grains per spike > flowering > maturity > Fusarium > Rhizoctonia > stripe rust > powdery mildew. That the region close with the production of major agronomic traits for the panicles, grain weight, grain number.
