摘要
为探究不同EMS处理时间对大豆诱变后代主要品质含量变化的影响,文章利用0.5%EMS溶液处理大豆高蛋白品系公交1057-1,分别浸泡4、7和10 h(清水冲洗处理为对照),对播种后获得的连续4代诱变后代主要品质含量变化进行分析。结果表明,与对照相较,经EMS处理后的植株成活率随处理时间延长而降低。其中,经EMS-4处理后的植株成活率最高,为43.5%;经EMS-10处理后的植株成活率最低,仅为16.0%。不同EMS处理时间对大豆诱变后代的蛋白质含量影响显著,对脂肪含量影响不明显。其中经EMS-4处理的诱变后代蛋白质含量高于其他3组处理;经EMS-4处理后的M2代蛋白质含量发生显著分离,并出现超亲个体,脂肪含量变化不显著。
In order to study the effect of different EMS treatment time on the main quality content of soybean induced progenies,0.5%EMS solution was used to treat high protein soybean line Gongjiao 1057-1 for 4,7 and 10 h respectively,the changes of main quality contents in four generations of induced mutation progenies after sowing were analyzed.The results showed that compared with the control,the survival rate of EMS-treated plants decreased with the prolongation of treatment time.EMS-4 had the highest survival rate(43.5%)and EMS-10 had the lowest survival rate(16.0%).Different EMS treatment time had significant effect on protein content,but had no significant effect on fat content.The protein content of EMS-4 treatment was higher than that of the other three treatments.After EMS-4 treatment,the protein content of M2 generation was significantly separated,and the superparent individuals appeared.The change of fat content was not significant.
