Abstract

Hop (Humulus lupulus L.) breeding is a lengthy process due to the dioecious nature of hop producing highly heterozygous offspring, and only female plants are of commercial interest. Marker assisted selection can be invaluable in breeding programs using markers linked to genes that encode resistance to different diseases and pests. The damson hop aphid (Phorodon humuli Schrank) is a very important pest in hop fields and effects over 90% of world growing areas. This paper presents the application of RAPD and AFLP methods for screening markers related to damson hop aphid resistance in hop. In an analysis of resistant and susceptible parents, ten DNA markers were identified as potential markers for resistance and they will be tested on F1 families derived from crosses between susceptible and resistant hop genotypes.
