Genetic divergence of Oblacinska sour cherry (Prunus cerasus L.) clones

Abstract

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.
