春小麦几个数量性状与产量的灰色关联分析

Grey Relevancy Analysis between Several Quantitative Characters and Yield on Spring Wheat

应用灰色系统理论分析方法,对东北春小麦中晚熟生态区8个主栽品种的产量与其他几个数量性状进行了综合分析。结果表明:中晚熟小麦品种的产量与各数量性状间的灰色关联位次是:穗粒数>株粒重>千粒重>株高>株穗数>穗长>小穗数,这从农艺性状方面为今后春小麦育种提供了参考依据。

The method of grey system theory was used to analyze yield and the several quantitative characters which affected the yield with 8 main plant spring wheat varieties from the mid-late-maturing zoology region of northeast. The results showed that grey relevancy order of yield and several quantitative characters were in turn： Number of main spikes〉kernel weight per plant〉 1000-grain weight〉 plant height〉spikes per plant〉length of ear〉 Number of main spikes. The results also provided a referenced basis for spring wheat breeding from agronomic characters in future.
