| 摘 要：不同浓度的甲基磺酸乙酯(EMS)处理大豆合子，对M1植株生长发育有强烈的抑制作用，M2出现的突变类型较多，比较明显的有晚熟、黄化、矮化、缺绿素、半不孕等，且多数性状仍在分离，M3继续出现新的变异。对有益变异进行定向选择，选育出4个新品系，比对照冀豆7号增产11.8%～26.5%。 |

Abstract： Different concentrations of EMS (ethylme thane sulphonate)solution were used to treat soybean zygot. The results showed that EMS intensively inhibited M1 growth and developenent, and a series of mutant types were observed in M2 generation, such as late-mature, yellowish, dwarf, chloriphyll defect, parital steril etc. Most ecomnic traits continuently segregated in following generations. 4 lines were selected out from elite mutants, which the yield was higher than the check (Jidou No.7) by 11.8%～26.5%. |
