摘　　要：利用高效液相色谱法检测了中豆27(♀)×九农20(♂)重组自交系的异黄酮含量。结果显示重组自交系间异黄酮含量差异显著。分析了异黄酮含量同主要农艺性状和化学品质性状的相关性,结果表明:总异黄酮含量与蛋白含量、脂肪含量、蛋白脂肪总含量、分枝数、单株产量、总荚数、主茎荚数和分枝荚数呈现负相关,其中与蛋白含量和蛋白脂肪总含量相关都分别达到显著和极显著水平;同株高、主茎节数和百粒重呈正相关趋势,并进一步估算了各异黄酮的含量与主要农艺性状的通径系数。To investigate the correlation between the isoflavone content and the major agronomic traits, as well the chemical qualities traits in soybean, HPLC was used to measure the isoflavones content of RILs from a cross by high isoflavones and low isoflavones cultivars. The correlation coefficients between soybean isoflavones and the major agronomic characters, as well chemical qualities traits were calculated. The results showed that the correlation coefficients between total isoflavones content and the content of protein, fat, the total content of protein and fat, number of branch, seeds weight per plant, number of total pods, number of pods in main stem, number of pods in branch were negative; the correlation coefficients were positive between total isoflavones content and height of plant, number of main stem nodes, and 100-seed weight. The path-coefficients were calculated based on the above correlation results.
