Symptoms of prematurely yellowing and leaf roll in the summer were observed in apricot, peach and sour cherry orchards in the East Bohemia (Czech Republic) during 2009-2010. Samples from selected symptomatic trees were tested by PCR assays followed by RFLP analyses. Detected phytoplasmas were classified in the apple proliferation group, subgroup 16SrX-B, which representative strains are apricot chlorotic leaf roll and European stone fruit yellows. Although the majority of symptomatic trees was observed in apricot orchards, out of 54 apricot trees examined by PCR/RFLP assays, only 10 plants were positive (18,5 %) to phytoplasma presence. In the peach orchards, phytoplasmas were detected in 4 trees out of 14 plants tested (28,6 %). Total number of trees examined from sour cherry orchards was 25, out of these 9 plants revealed positive reactions (36 %). DNA sequencing of phytoplasma strain from one sour cherry tree confirmed the RFLP identification as Candidatus Phytoplasma prunorum.
