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。
Based on the data of 8 soybean parents, 6 crosses were made and the correlations were analyzed between the protein content of F2 ~ F6 and the parental protein content and yield. The results showed that: (1) The protein content of each generation was significantly positively correlated with the female parent, but not significant with the male parent; (2) With the increase of the generation, the protein content of the high protein × high protein combination decreased first and then increased, The content of protein in F4 generation was the lowest, while the content of protein in high progenies × low protein combinations increased first and then decreased and the content of protein in F4 generation was the highest. (3) The content of protein in each generation was negatively correlated with the yield, but the correlation between high protein × low protein Not significant level, indicating that it may be bred high-yielding high-protein material.
