Abstract

The reaction of different apricot cultivars to PPV infection was studied in conditions of natural transmission of the virus in the field by aphids and artificial transmission of the virus by grafting.
Sixty two cultivars were examined in two plots located in an area where the disease is endemic.
The highly virulent PPV-M strain (Marcus) has previously been identified as the causal agent.
Observations of the disease symptoms on leaves and on fruits were recorded for five vegetative periods.
Artificial inoculation of the cultivars was carried out by grafting them onto old heavily PPV infected apricot trees.
The ELISA test was applied for the detection of the virus in leaf samples.
According to the results obtained the following cultivars presented resistance to Sharka disease in the field: Harlayne, Henderson, NJA₂. Stark Early Orange, Goldrich, Orange red, Sunglo, Avilana, Lito and Pandora.
