大豆主要生育性状与产量间的关系分析

Correlation Analysis of the Major Breeding Traits and Yield of Soybean

生育期、株高、分枝数、主茎节数、单株荚数、百粒重等性状是大豆主要生育性状。通过对生育期、株高、分枝数、主茎节数、单株荚数、百粒重等性状的相关分析和灰色关联度分析,结果表明,分枝数、单株荚数是影响产量的关键因素。

Maturity,plant height,branch number,nodes of main stem,pods per plant and 100-seed weight are main breeding traits,which affect soybean yields.Comparative analysis and grey correlation degree were carried on soybean traits,the results were as follows:branch number and pods per plant have more important effect on yields.
