- Abstract:
- The objective of this research was to test for aphid biotypes using two aphid isolates and seven soybean genotypes.The responses of two soybean aphid(Aphid glycines Matsumura)isolates,one collected in Shanghai and the other in Harbin,were compared by infesting seven soybean genotypes in unselective test.The same genotypes were also tested with the Shanghai isolate in a selective test.In the unselective test,soybean P746 and Jiangxi 9 were resistant to both Shanghai and Harbin isolates,while Dongnong 47 was heavily susceptible to the both.Jiangxi 33,Jiangxi 37 and Jiangxi 69 were resistant to Harbin isolate,but susceptible to Shanghai isolate.In addition,Jiangxi 22 was resistant to Shanghai isolate,but susceptible to Harbin isolate.In the selective experiment,P746(DI=25%)and Jiangxi 9(DI=25%)were a little damaged by Shanghai isolate;but the other four soybean genotypes,such as Dongnong 47,were severely damaged(DI=68%75%).These results indicated that Shanghai aphid isolate is different from Harbin aphid isolate.
