Zmienność genetyczna cisa w wybranych rezerwatach Polski

Genetic variability of yew (Taxus baccata L.) trees in seven nature reserves (Jasień, Czarne Człuchowskie, Choczewo, Wierzchlas, Wirty, Rokita and Mogilno/Stary Sącz) in Poland was investigated by RAPD methods. The results showed high genetic differences between populations ranging from 22.7% among the population of Stary Sącz and hedge (+) to 86.1% between Wierzchlas and Rokita (+). Based on the results of RAPD analyses, the studied populations were divided into three groups of similarity. The first include Jasień and Choczewo the populations, the second Rokita (+), hedge (–) and Stary Sącz, and the third remaining populations. High level of genetic diversity was showed among the studied populations, is essential to the adaptability of the population of yew. This theoretically increases the chances of survival species thanks to the possibility of passing to preferred combinations of genes to the future generations.
