| 摘 要： | 在大田和室内条件下，采用大量蚜虫侵染幼苗法评价4个苜蓿（Medicago sativa）品种对豌豆蚜（Acyrthosiphon pisum）的抗性，以筛选出对豌豆蚜高抗的材料。结果表明，甘农5号（HA 3）在大田和室内的抗性植株百分率均显著高于其他品种，分别为50.3%和48.9%，而猎人河的抗性植株百分率在大田和室内均较低，分别为4.0%和4.3%；4个苜蓿品种在大田的抗性级别为甘农5号高抗，甘农3号、金皇后、猎人河均为感虫，室内抗性级别为甘农5号抗虫，金皇后、甘农3号低抗，猎人河感虫。

| Abstract: | The resistance of 4 alfalfa(Medicago sativa) cultivars to pea aphid(Acyrthosiphon pisum) was evaluated by mass-infesting young seedlings in the field and lab to select high resistant cultivars to pea aphid.The results of this study showed that the Gannong No.5(HA-3)showed the strongest resistance and its percent of resistant plants accounted for 50.3% and 48.9% in the field and lab experiments,respectively.The Hunter River showed a poor resistance and its percent of resistant plant was only 4.0% and 4.3% in the field and lab experiments,respectively.The field experimental results showed that Gannong No.5 was high resistance cultivar,and Gannong No.3,Golden Empress and Hunter River were susceptible cultivars;the lab experimental results showed that Gannong No.5 was high resistance cultivar,and Gannong No.3 and Golden Empress were low resistance cultivars,and Hunter River was susceptible cultivar. |
