应用灰色关联度分析评价不同大麦品种产量与产量构成因素

Application of Grey Correlation Degree Analysis and Evaluation in Different Barley Varieties on Yield and Yield Components

运用灰色系统理论,对重庆市7个大麦品种的6个主要农艺性状与产量进行灰色关联度分析。结果表明,重庆地区大麦产量构成因素对产量影响大小的顺序为:穗粒数>小穗数>有效穗>千粒重>穗长>株高。

The barley yield and yield components were analyzed with the analysis method of Grey Correlation Degree in Chongqing City. The results showed that the sequence of yield components affecting barley yield in Chongqing region ： grains per spike 〉 Spikelet number 〉 The ef- fective spike 〉 1000-grain weight 〉 Ear length 〉 Plant height.
