摘　　要：在苜蓿雄性不育系杂交制种的基础上，以敖汉苜蓿为对照，以加混苜蓿和抗蓟轮苜蓿为参试品种，对杂交Ｆ１代的综合性状进行了测定，３年的试验结果表明，杂种Ｆ１代的产量与对照相比平均增产２５．２％，且综合性状也显著高于对照。Based on the Male Sterility’ to hybrid seed making, the synthetic characters of F 1 generation were tested when the control was M. Sativa L. cv. “Aohan” and trial cultivars were “Jiahun” and “kangjilun”. The 3-year-experiment results showed that yield of F 1 increased by 25.2%, its synthetic characters was superior to control and it had significant hybrid vigor.
