Oblaèinska višnja predstavlja sortu populaciju koja obuhvata veliki broj formi razlièitih
po bujnosti, rodnosti, vremenu sazrevanja, krupnoæi, boji i kvalitetu plodova. Pošto
Oblaèinska višnja nije jedan klon (genotip) veæ smeša velikog broja klonova
(genotipova) nameæe se potreba izdvajanja genetièki divergentnih formi za eksploataciju
i dalji oplemenjivaèki rad. U ovom radu prikazani su rezultati analize 10 selekcionisanih
klonova Oblaèinske višnje. Ogled je izveden na OD «Radmilovac» Poljoprivrednog
fakulteta u Beogradu. Tokom trogodišnjeg perioda istraivanja analizirane su sledeæe
osobine: vreme sazrevanja, prinos, masa ploda, masa koštice, randman, duina peteljke
ploda, sadraj rastvorljivih suvih materija, sadraj ukupnih kiselina, sadraj ukupnih
šeæera i sadraj invertnih šeæera. Genetièka divergentnost izmeðu prouèavanih klonova
ustanovljena je primenom hijerarhijske klaster analize. Korišæen je UPGA metod, pri
èemu je razlika izmeðu grupa izraena preko Euklideanovog rastojanja. Na dobijenom
dendrogramu izdvojeno je èetiri grupe srodnih klonova. Razdvajanje klonova u grupe
bilo je prvenstveno u funkciji njihovog prinosa, mada su uticaj na razdvajanje imale i
ostale prouèavane osobine.
GENETIC DIVERGENCE OF OBLAÈINSKA SOUR
CHERRY CLONES (Prunus cerasus L.)
Oblaèinska sour cherry represents the population of a cultivar encompassing a great number
of forms different on vigor, yielding, ripening time, size, color and quality of fruits.
The need arises to separate the genetically divergent forms for further exploitation and
breeding considering the fact that Oblaèinska sour cherry is actually a mixture of a great
number of clones (genotypes). The results of the analysis of 10 selected clones of
Oblaèinska sour cherry are given in this paper. The experiment was conducted at the Experimental
Station «Radmilovac» of the Faculty of Agriculture in Belgrade. A three-year
trial was carried out in order to test the following properties: ripening time, yield, fruit
weight, stone weight, randman, stalk fruit length, soluble solid content, total acid content,
total sugar content and invert sugar content. 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 dendogram. The objective of
clone differentiation was primarily yield, although other properties were taken into account
as well.
