Four clonal progenies of wild cherry obtained using an in vitro technique and control progeny of generative origin were tested on the Polná research plot in southeastern Bohemia. Growth characteristics of cherry trees were determined each year during the period 2000–2010. At the age of 15 years, the progenies reach mean heights of 4–9 m and diameter at breast height (DBH) of 5–10.5 cm. The determined differences in height and DBH between progenies are statistically significant. Cherry trees of generative origin and progeny of clone No. 14 grow markedly slower in comparison with clones Nos 24, 26 and 28. The values of growth characteristics for verified clones are comparable with similar findings from abroad. The in vitro plantlets of wild cherry achieve similar growth characteristics as generative seedlings.
