摘　　要：为探讨昆虫为杂交大豆授粉的行为,提高授粉效率,以大豆细胞质雄性不育系JLCMS34A和保持系JLCMS34B为材料,研究父母本3种行距配置(T1、T2、T3)对昆虫授粉行为及产量构成的影响。结果表明:行距配置T2条件下昆虫授粉效率最高,母本单株粒数最多,为45.98个(2011年),与T1、T3差异达到显著水平,T3配置授粉效率最差,单株粒数最少,为32.06个(2012年),与T1、T2差异达到极显著水平。在吉林省洮南地区适当缩小父母本行距,增加母本间行距可有效促进昆虫授粉效率,提高结实率。This paper aims to study the relation between hybrid soybean distance and pollinating insects to improve the pollina- tion efficiency. In this paper, soybean cytoplasmic male sterile line （JLCMS34A） and its maintainer line （JLCMS34B） were used to study the effect of three treatments of parents row-spacing （ T1, T2 and T3 ） on the efficiency of insect pollination and the production of the hybrid seed of soybean. The results showed that the T2 row-spacing treatment had the highest efficiency of insect pollination and the maximum grain number per female plant, which differ significantly from that of T1 and T2 row- spacing treatment （ P 〈 0. 05 ）. The maximum grain number per female plant on T2 row-spacing treatment was 45.98 in 2011. In addition, the 33 row-spacing treatment had the lowest efficiency of insect pollination and the minimum grain number per fe- male plant, which differ significantly from that of T1 and T2 row-spacing treatment （P 〈 0.01 ）. The minimum grain number per female plant on T3 row-spacing treatment was 32. 06 in 2012. This paper concluded that narrowing parents row-spacing and widening female row-spacing in Taonan, Jilin province could effectively improve the efficiency of insect pollination and seed setting percentage.
