Virus incidence in Australian hop (Humulus lupulus L.) gardens and cultivar differences in susceptibility to infection

Abstract

0uo;Victoria’ (98%) was significantlyhigher than in ‘T11’ (58%), which was higher than‘Opal’ (31%). Results suggested that ‘Victoria’was more susceptible to infection by all 3 viruses than traditionally growncultivars and recently released or experimental cultivars. Planting with elitematerial and roguing of infected plants has been ineffective as a viruscontrol strategy with this cultivar.
