本文用野生大豆、种间杂交中间材料与栽培种大豆杂交， 配制９ 个组合， 分析了杂种Ｆ１ 代蛋白质含量的表现及与亲本的关系， 同时也分析了种间杂交组合Ｆ２ 代蛋白质含量的变异。结果表明： 种间杂交后代的Ｆ１ 代蛋白质含量明显的倾向高蛋白野生亲本。Ｆ２ 代蛋白质含量株系间变异幅度很大， 呈现明显分离， 表现为连续变异， 广泛分布， 并出现部分正向、负向超亲单株。种间中间材料杂交组合后代的Ｆ１ 代蛋白质含量一般为介于两亲之间的中间型；在正反交组合中， 母本蛋白质含量对杂种Ｆ１ 代蛋白质含量影响较大； 以同一种种间中间材料为母本，不同种栽培种大豆为父本的杂交组合后代Ｆ１ 代蛋白质含量受父本影响较大；以不同种种间中间材料为母本，同一种栽培种大豆为父本的杂交组作品Ｆ１ 代蛋白质含量受母本的影响较大。不同杂交组合后代Ｆ１ 代蛋白质含量与父母本平均蛋白质含量的相关性呈极显著正相关
In this paper, 9 combinations were prepared by crossing wild soybean and interspecific hybrid materials with soybean cultivars. The protein content of F1 hybrids was analyzed and their relationships with parents were analyzed. The variation of F2 protein content in interspecific hybrids was also analyzed . The results showed that F1 progeny of interspecific hybrids tended to express high protein wild parents. The variation of protein content of F2 generation was very large, showing a clear separation, showing continuous variation, widely distributed, and some positive and negative super-progeny single plant. The F1 protein content in F1 progenies of cross between interspecific hybrids was generally intermediate between amphibians. In reciprocal crosses, the protein content of female parent had a greater effect on the protein content of F1 hybrids. The interspecific interspecific crosses The results showed that the F1 progeny had a significant effect on the protein content of the F1 progeny of crosses between the parents of different cultivars and the parents of the hybrid cultivars with the same cultivated soybean as the male parent The F1 protein content is more affected by the female parent. The correlation between the protein content of F1 generation and the average protein content of parents was extremely significant positive correlation
