anglais. The work is focused on the evaluation of variability of morphological and pomological characteristics of several old sweet cherries (Prunus avium L.) that were found in different Slovak regions. The experimental work has been performed during two years, 2014 and 2015. The following characteristics according to the descriptor list of subgenus Cerasus were evaluated – period of flowering and ripening, morphological characteristics of the flowers, fruit size, fruit weight, and quality parameters. The results showed high variability of evaluated accessions. From the 13 surveyed localities, the most valuable accessions were found in the locality Horná Streda – places Èachtice, Krakovany, Nitra, and Brdárka. During the collecting expeditions, 170 accessions of sweet cherry, with fruit of the different quality were found. The most interesting accessions were grafted onto rootstocks with different intensity of growth (Prunus avium L., Prunus mahaleb L., and ‘Gisela5’). Some of the selected cherry accessions can be used for commercial growing after tests, while some of them can be used only for collection of genetic resources and as potential genitors in breeding programmes.

Eksperimentālais darbs veikts 2014. un 2015. gadā. Saskaņā ar Cerasus apakšģints deskriptoriem tika noteiktas sekojošas pazīmes – ziedēšanas un augļu gatavošanās laiks, ziedu morfoloģiskās īpašības, augļu izmērs, svars un kvalitātes rādītāji. Novērtēto genotipu rezultātos atklājās augsta variabilitāte. No 13 apsekotajiem apvidiem vērtīgākie genotipi tika atrasti Horna Streda apvidū – vietās Čahtice, Krakovani, Nitra un Brdarka. Ekspedīcijās atrada 170 saldo ķiršu genotipus ar dažādas kvalitātes augļiem. Interesantākie genotipi tika potēti uz dažāda auguma potcelmiem (Prunus avium L., Prunus mahaleb L. un ‘Gisela5’). Dažus no izdalītajiem ķiršu genotipiem pēc pārbaudes varētu izmantot komerciālai audzēšanai, bet daži no tiem ievietojami ģenētisko resursu kolekcijā tālākai izmantošanai pētījumos un selekcijā.
