During three years we investigate the main phenological and pomological
properties of four highbush bluebery in Cacak ecological conditions. Results showed
significant variation of properties evaluated among cultivars and years with inconsistent
behavior of cultivars in some seasons. The highest bunch weight and berry number per
bunch had cv. Reka, whereas the lovest valuaes was found in Ozarkblue and Nui,
respectively. The highest berry weight had cvs. Ozarkblue in 2011 and Nui in 2012,
respectivelz, whereas diferences in 2014 were not significant. The highest and similar
soluble solids content had berries of cvs. Ozarkblue and Reka in 2012, and Reka i Duke
in 2014, respectively, whereas differences among cultivars were not significant. The
lowest soluble solids content had cv. Nui. Statisticaly significant correlations among
blueberry properties evaluated were not determined. The prinicipal component analyisi
(PCA) can be served as confidental model for segregation or grouping cultivars with the
most favourable phenological and pomological properties. Tokom tri godine, ispitivane su najznačajnije fenološke i pomološe osobine
četiri sorte visokožbunaste borovnice u ekološkim uslovima Čačka. Rezultati su pokazali
značajna variranja ovih osobina između sorti i godina ispitivanja, uz nedosledno ponašanje
sorti u pojedinim sezonama. Najveću masu grozda i broj bobica po grozdu imala je sorta
Reka, a najmanje vrednosti su utvrđene kod sorti Ozarkblue, odnosno Nui. Najveću masu
bobica imala je sorta Ozarkblue u 2011. godini, odnosno Nui u 2012., dok razlike u 2014.
godini nisu bile značajne. Najveći i sličan sadržaj rastvorljive suve materije (RSM) imale
su bobice sorti Ozarkblue i Reka u 2012. godini, odnosno Reka i Duke u 2014., dok
razlike između sorti u 2011. nisu bile značajne. Najmanji sadržaj RSM je imala sorta Nui.
Nisu utvrđene statistički značajne korelacije između ispitivanih osobina borovnice.
Analiza najznačajnijih komponenti (PCA) može poslužiti kao pouzdan model za
izdvajanje ili grupisanje sorti sa najpovoljnijim fenološkim i pomološkim osobinama.
