The genetic diversity of re-established population of endangered species Allium angulosum L. was tested as a one part of rescue program. Founder individuals were picked in Chropyně - Záříčí area (North Moravia, Czech Republic) and new population was set in Protected Landscape Area Litovelské Pomoravi (North Moravia, Czech Republic). The task was whether the newly founded population was made by representative individuals to cover (include) the genetic variability of source (mother) population. Items were tested with variability assay of six isozyme systems (G-6-PDH, AAT, PGM, EST, ACP, PGI) using discontinuous polyacrylamide gel electrophoresis (PAGE). The method stated relatively sufficient level of variability on condition that new population would be raised to prevent genetic changes. Application of more tests checking the genetic diversity within population could be useful during reintroduction and management of endangered plant species.
