Abstract:

The field resistance of different alfalfa (Medicago sativa) varieties to Acyrthosiphon pisum Harris was evaluated using aphid index and the rate of resistant plants as evaluation indices. Results show that the highest aphid index detected in China alfalfa No.1 is 82.48 and the lowest one is 26.00 in Algangjin compared with others, while the highest rate of resistant plants found in Algangjin is 93.50 and the lowest one is 2.36 in Hunterriver. The 16 of 28 tested alfalfa varieties such as Gannong No.5, Sandili and Algangjin have higher resistance to A. pisum. Six tested alfalfa varieties such as Algangjin, Gold empress and Gannong No.3 are resistant varieties. Cropper nine, Tianshui and 75-43 have moderate resistance and Weinan has low resistance. Hunterriver and China alfalfa No.1 are susceptible to A. pisum.

摘要：

以感蚜指数和抗蚜株率为指标，评价28个苜蓿（Medicago sativa）品种对豌豆蚜（Acyrthosiphon pisum）的田间抗蚜性。结果表明：感蚜指数以中苜1号最高为82.48，阿尔刚金最低为26.00；抗蚜株率阿尔刚金最高为93.50，猎人河最低为2.36。28个苜蓿品种中甘农5号、三得利、阿尔刚金等16个为高抗品种；金皇后、甘农3号等6个为抗性品种；Cropper nine、天水、75-43为中抗品种；渭南为低抗品种；猎人河和中苜1号为感虫品种。
