摘　　要：以细胞质雄性不育系JLCMS82A和其保持系JLCMS82B为试材,采用裂区试验设计,在田间开放条件下对不同苜蓿切叶蜂释放量和父母本种植方式下的制种效果进行了研究。结果表明:不同放蜂量处理之间不育系结实率和不育系与保持系总产量的差异达极显著水平,不育系间的产量差异达显著水平;保持系与不育系不同行比处理间的结实率以及不育系与保持系总产量的差异达极显著水平,而不育系间的产量差异不显著;放蜂量与行比间的互作差异不显著。不同放蜂量下,每公顷放3万头蜂时不育系的结实率、产量及总产量达最高;不同行比下,不育系间的产量差异并不显著,而父母本1:1时不育系的结实率和总产量最高。综合评价,在每公顷释放3万头苜蓿切叶蜂并以父母本1:1行比种植时,不育系的结实率、产量以及不育系加保持系总产量均达最高,制种效果最佳。The line JLCMS82A and its maintainer line JLCMS82B were used in this trial with a split block design for evaluating the effects of cross-pollination of alfalfa leafcutting bees in different treatments of bee amount and row cytoplasmic male sterile（CMS） ratio of male and female parents.The results showed that the seed setting of the CMS line and the whole yield of the male and female parents existed significant difference at the 1% level and the yield of the CMS line at the 5% level among the different treatments of bee amount.There was significant difference at the 1% level in the seed setting of the CMS line and the whole yield of the male and female parents,whereas the difference of the yield of the CMS line was not significant among the different treatments of row ratio of male and female parents.There was no significant difference between the treatments of bee amount and row ratio of male and female parents.In the treatment of different bee amount,the highest seed setting and yield of the CMS line and the whole yield of the male and female parents were observed when the amount of alfalfa leafcutting bees reached 30,000/ha.In the treatment of different row ratio of male and female parents,the highest seed setting and whole yield of the male and female parents were also observed when the row ratio was 1：1,whereas there was no significant difference for the yield of the CMS line between the different row ratio.On the whole,the best effective treatment was that of the 1：1 row ratio with the amount of 30,000 alfalfa leafcutting bees per hectare.
