摘 要 ：1985-1990年用两套亲本的单、双交是否较单交更优越。结果表明：单、双交组合F2代的株高、主茎节数、单株荚数、单株粒数、百粒重、单株粒重的平均表现、标准差及变异系数无大差异。双交组合多数性状的变异幅度处在两个单交组合之间。除第二套组合双交的主茎节数同时显著少于两个单交外，其余性状均未能同时达到显著水平。按

Abstract:The performances of the progenies and the selection effects of 2 sets of single and 4-way crosses of soybean were studied comparatively in order to accertain whether the 4-day crosses is superior to the single cross. The results indicated that the average performance,standard error and coefficients
