Abstract: The reaction of 19 Slovak apricot cultivars and hybrids (breeding program of Research Breeding Station at Vesele) to infection by M isolates of plum pox virus (PPV-M) was evaluated. The genotypes were inoculated by grafting to naturally infected plum trees in the field and by chip-budding in the glasshouse. Monitoring of PPV infection was done over a 3 year period by visual inspection and DAS-ELISA. In the third year of evaluation the RT-PCR assay was also applied. The tested apricot genotypes differed in their reaction to PPV infection. Most of them developed mild or severe symptoms on leaves in the first year and/or next two consecutive years after artificial inoculation. The four Slovak apricot genotypes Veharda, Vemina, VS 15811 and VS 157/8 were resistant to PPV-M infection.
