Description
Summary:Based on examination of 10 important pomologic and technologic properties, genetic divergence of 10 selected Oblacinska sour cherry clones was established. The genetic divergence between the analyzed clones was determined using the hierarchical cluster analysis. The UPGA method was used and the Euclidean distance in order to determine the difference between the groups. Four similar clone groups were obtained on the dendrogram. The objective of clone differentiation was primarily yield, although other properties were taken into account as well. As the most yielded clones for the production, that can be recommended, were clone D8 or clone D4 that are genetically very similar, and clone D3. Oblacinska visnja predstavlja sortu populaciju koja obuhvata veliki broj formi razlicitih po bujnosti, rodnosti, vremenu sazrevanja, krupnoci, boji i kvalitetu plodova. Posto Oblacinska visnja nije jedan klon vec smesa velikog broja klonova (genotipova) namece se potreba izdvajanja geneticki divergentnih formi za eksploataciju i dalji oplemenjivacki rad. U ovom radu prikazani su rezultati analize 10 selekcionisanih klonova Oblacinske visnje. Ogled je izveden na OD "Radmilovac" Poljoprivrednog fakulteta u Beogradu. Tokom trogodisnjeg perioda istrazivanja analizirane su sledece osobine: vreme sazrevanja, prinos, masa ploda, masa kostice, randman, duzina peteljke ploda, sadrzaj rastvorljivih suvih materija, sadrzaj ukupnih secera, sadrzaj invertnih secera i sadrzaj ukupnih kiselina. Geneticka divergentnost izmedju proucavanih klonova ustanovljena je primenom hijerarhijske klaster analize. Koriscenje UPGA metod, pri cemu je razlika izmedju grupa izrazena preko Euklideanovog rastojanja. Na dobijenom dendrogramu izdvojeno je cetiri grupe srodnih klonova. Razdvajanje klonova u grupe bilo je prvenstveno u funkciji njihovog prinosa, mada su uticaj na razdvajanje imale i ostale proucavane osobine. Kao najprinosniji za proizvodnu praksu mogu se preporuciti klon D8 ili klon D4 koji su geneticki veoma bliski i klon D3.
