| 摘 要： | 在田间评价了8个马铃薯品种Cardinal,Ultimus,Cosima,Mansur,Monaliza,Ajax,Diamant和Desiree对桃蚜Ｍyzus persicae(Sulzer)的抗生性。结果表明在所有品种中，Cardinal对桃蚜表现出相对较高的抗生性，用其繁殖的桃蚜具有最低的内禀增长率（rm)，其次为品种Ultirmus;在品种Cardinal上繁殖的桃蚜其内禀增长率（rm)比在最敏感的品种Desiree上小1.6倍。

| Abstract: | Eight potato cultivars i.e. Cardinal, Ultimus, Cosima, Mansur, Monaliza, Ajax, Diamant and Desiree were screened for their relative antibiosis in the potato field to peach-potato aphid, Myzus persicae (Sulzer). Among all the tested cultivars, Cardinal showed comparatively high resistance and showed the lowest r_m, followed by Ultimus. The r_m for Cardinal was 1.6 times lower than that of r_m on Desiree, which was found consistently the most susceptible cultivar. |
