Abstract Background Raspberry breeding programmes worldwide aim to produce improved cultivars to satisfy market demands and within these programmes there are many targets including increased fruit quality yield and season and improved pest and disease resistance and plant habit. The large raspberry aphid Amphorophora idaei transmits four viruses and vector resistance is an objective in raspberry breeding. The development of molecular tools that discriminate between aphid resistance genes from different sources will allow the pyramiding of such genes and the development of raspberry varieties with superior pest resistance. We have raised a red raspberry Rubus idaeus F progeny from the cross Mailing Jewel X Malling Orion MJ X MO which segregates for resistance to biotype 1 of the aphid .
