灰色关联分析在宁夏春大豆育种数量性状选择上的应用

Application of Grey Relational Analysis in Quantitative Trait Selection of Ningxia Spring Soybean Breeding

[目的]研究灰色关联分析方法在宁夏春大豆育种数量性状选择上的应用。[方法]分析了宁夏春大豆主要数量性状与产量之间的关联度。[结论]关联度大小依次为百粒重>株高>生育天数>主茎节数>结荚底高>有效结荚数>单株粒数>分枝数。[结论]为宁夏春大豆高产育种数量性状选择及栽培提供理论依据。

[Objective]The aim was to study application of grey relational analysis in quantitative trait selection of Ningxia spring soybean breeding.[Methods] The correlation between quantitative traits of Ningxia spring soybeans and yield was analyzed.[Result] The study showed that the order of correlation was： kernel weight〉 height;fertility days〉nodes on main stem〉pod base height〉effective pod〉seed number per plant〉branch number.[Conclusion] The study provided the theoretical basis for quantitative trait selection of Ningxia spring soybean breeding and cultivation.
