摘要
试验采用^(60)Coγ—射线以9.3,13.95,18.6千拉德3种剂量分别处理半野生大豆“药泉山”和“龙79-6613”,在M_2代测定其蛋白质和脂肪含量。结果表明,M_2代群体蛋白质平均含量较对照增加,而脂肪平均含量较对照减少,且均有超亲现象。对蛋白质含量进行选择可获得一定的预期遗传进度。简单相关分析表明,蛋白质含量与脂肪含量及单株粒数呈极显著负相关,而与百粒重呈极显著正相关,脂肪含量与生育日数呈极显著正相关。
An attempt was made to investigate the variation in oil and protein content of semi-wild soybean induced by gamma rays. Two semi-wild soybeans were treated by 60Co γ-rays with dosages of 9.3 K Rad, 13.95 KRad, 18.6KRad,in the experiment,respectively.Oil and protein content of the semi-wild soybeans were analysed in the second generation.The results demonstrated that the protein content of treated population was higher than that of control and the oil content of treated population was lower than that of control in the second generation. The higher expected genetic advance was obtained for the selection of protein content in the second generation. Simple correlation analysis revealed that oil content and seed number per plant were apparently negatively correlated with protein content. Protein content was apparently positively correlated with 100 seed weight. Oil content was positively correlated with growing date.
