春谷产量与其相关性状的关联度分析

Grey Connected-degree Analysis of Yield and Correlated Traits in Spring Millet

应用灰色系统理论中的关联度分析法 ,对 1 998～ 2 0 0 0年中国北部高原七省区春谷联合区域试验中晚熟区组 7个品种的 8个性状进行分析。结果表明 :各性状对产量的影响大小依次为出谷率、谷草比、单株粒重、单株穗重、千粒重、株草重、株高、穗长。通过分析指出各性状对产量影响的主次关系 。

Eight traits of 7 Spring millet in North-high-area of China from 1998 to 2000 were analysed by the method of grey connected degree.The effects of spring millet yield in turn were product-millet-rate,millet-plant-rate,seed weight of per plant,weight per ear, 1000-seed weight,weight per plant,plant length,ear length.The primary and secondary ralations of yield traits may provide the foundation of theory foundation for the breeding of spring millet.
