Abstract

Incidence of hop latent virus (HpLV), hop mosaic virus (HpMV), and Prunus necrotic ringspot virus [PNRSV (apple, A, and intermediate, I, serotypes)] was assessed in 6 Australian-bred hop cultivars in Tasmania and Victoria, Australia. At Gunns Plains, Tasmania, virus incidence in 5 gardens of cv. 'Victoria', initially established with elite material and 7-9 years old, was 89-98% for HpLV, 72-96% for HpMV, and 85-100% for PNRSV (A & I). Virus incidence in 13 'Pride of Ringwood' gardens, 10-19 years old and initially established from material of unknown virus status, was 0-49% for HpLV, 0-69% for HpMV, and 0-77% for PNRSV (A & I). In an 8-year-old trial, in which 3/4 cultivars were planted with elite material, incidence of HpLV in 'Victoria' (47%) was significantly (P < 0.001) greater than in `Opal' (8%). Incidence of HpMV in 'Victoria' (52%) was significantly (P < 0.001) higher than in 'T11' (42%), which in turn was higher than in 'Opal' (24%). Incidence of PNRSV (A & I) in 'Victoria' (98%) was significantly higher 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 grown cultivars and recently released or experimental cultivars. Planting with elitematerial and roguing of infected plants has been ineffective as a virus control strategy with this cultivar.
