title: Clonal micropropagation of essential oil rose cultivars and breeding samples at long-term subcultivation<i>in vitro</i>
abstract: The development of explants of 12 cultivars and breeding samples of essential oil rose (obtained with the participation of Rosa damascena Mill., R. gallica L., R. alba L.) during long-term micropropagation was investigated. At the second multiplication stage 5 subcultures were carried out. Increase of the studied morphometric parameters of explants to 3-4 th subcultures was established. In some genotypes, the maximum multiplication index was in the third subculture (сultivars ‘Raduga’, ‘Zolushka
