摘　　要：以8个大豆亲本为材料组配6个杂交组合,并对F2～F6各世代的蛋白质含量与亲本蛋白质含量及产量进行相关性分析。结果表明:(1)各世代蛋白质含量与母本显著正相关,与父本相关性不显著;(2)随着世代的升高,高蛋白×高蛋白组合后代蛋白质含量先降低后升高,F4代蛋白质含量最低,而高蛋白×低蛋白组合后代蛋白质含量先升后降,F4代蛋白质含量最高;(3)各世代蛋白质含量与产量呈负相关,但高蛋白×低蛋白组合的相关性未达显著水平,说明从中可能选育出高产高蛋白的材料。Six hybrid combinations were made from eight soybean cultivars （ lines）, and divided into four high protein ×high protein（ H ×H） and two high protein × low protein（ H ×L） combination. Protein content of filial generation and parents were determined and the correlation between protein content and seed yield were analyzed. Results showed （ i ）Protein content in filial generations significant positively correlated with that of their female parents, while no correlation with male parents; （ ii ） For H ×L combinations, with the increase of generations, the protein content showed first increase and then decrease trend and peaked at F4 ,while just on the contrary for H ×H combinations; （iii ） Protein content in filial generations all negatively correlated with seed yield, and the correlation in H × L combinations didn＇ t reach significant level,from which we can select soybean materials with high yield and high protein content. Key words： Soybean; Protein content; Yield; Correlation
