Abstract

Uz veliki broj sorata vinove loze (Vitis vinifera L.), danas se sve veća pažnja posvećuje
mogućnosti uzgoja sortata međuvrsnih hibrida s otpornošću na gljivične bolesti i abiotske
stresove. Sorte međuvrsnih hibrida nastale su križanjem sorata vinove loze (Vitis vinifera L.) i
nekih drugih vrsta roda Vitis. Uz međuvrsne hibride često se veže i prisutnost nekih
nepoželjnih aroma (najčešće se navode tzv. foxy ili strawberry-like arome) podrijetlom od
aromatskih spojeva identificiranih u najstarijim generacijama međuvrsnih hibrida. Zato se pri
evaluaciji ovih sorata njihovom aromatskom profilu pridaje velika važnost. Istraživanje je
provedeno na 11 sorata. Analizirane sorte pripadaju međuvrsnim križancima nastalim u
oplemenjivačkim programima u Mađarskoj, Njemačkoj i Srbiji: „Bačka“, „Bianca“,
„Johanniter“, „Kozmopolita“, „Lisa“, „Merzling“, „Orion“, „Phoenix“, „Sirius“, „Solaris“ i
„Staufer“. U ovom istraživanju provedena je analiza sastava i koncetracije aromatskih spojeva
lociranih u kožici grožđa. Putem vezanog sustava plinska kromatografija-spektrometrija masa
(GC-MS) određen je aromatski profil sorata.

Abstract (english)

With great number of grapevine (Vitis vinifera L.) varietes, ever increasing attention
today is given to possibility of growing interspecies hybrids varietes with resistance on fungal
diseases and abiotic stresses. Interspecies hybrid varietes are created by crossing with varietes
of European grapevine (Vitis vinifera L.) and some other species of Vitis genus. Interspecies
hybrids are often associated with presence of some unwanted aromas (e.g. foxy and
strawberry-like aromas) that have originated from the oldest generations of interspecific
hybrid varietes. Thats why when these varietes aromatic profile is evaluated it is of great
importance whether are unwanted aromas present. Research was done on 11 varietes.
Analysed varietes belong to group of interspecies hybrids that were created in breeding
programms in Hungary, Germany and Serbia: „Bačka“, „Bianca“, „Johanniter“,
„Kozmopolita“, „Lisa“, „Merzling“, „Orion“, „Phoenix“, „Sirius“, „Solaris“ i „Staufer“.
Analysis of content and concentration of aromatic compounds that are located in grape skin
was done in this research. Aroma profile of varietes were determined by gas chromatography
coupled with mass spectrometry (GC-MS).
