Abstract excerpt

The large raspberry aphid, Amphorophora idaei, has several biotypes described by their abilities to overcome plant resistance genes. Bioassays of field populations showed a strong shift towards A1 resistance-breaking biotypes since the 1960s. RFLP analysis of the rDNA cistron was used to study variation found within and between standard clones of three A. idaei biotypes and twenty-nine field populations collected...
