Agro biological, economical and technological traits of recently developed domestic grape vine cultivar negotinka in Radmilovac

Abstract

Negotinka is a new domestic cultivar of grapevine developed by crossing of the cultivar Začinak to the cultivar Black Burgundy. It was multiplied and planted on the agricultural school farm of the Faculty of Agriculture Belgrade-Zemun - "Radmilovac". The investigation and monitoring of this cultivar was carried out in 2000 and 2003. The following major parameters were observed: grape yield, number and weight of grape clusters, sugar content and total acids content in must and alcohol percentage in wine. Grape yields varied from 2.446 to 6.566 kg per a grape cluster, grape cluster weights and numbers varied from 93.17 to 107.40 g, and 20.63 to 39.86, respectively, while the sugar content and total acids content in must varied from 20.42 to 21.50 percentage, i.e. 6.63 to 7.07 g l-1 respectively, and the alcohol content in wine varied from 10.91 to 11.91 percentage.

Negotinka je novostvorena domaća vinska sorta nastala ukrštanjem sorti začinak x burgundac crni. Ona je umnožena i zasađena na OŠD "Radmilovac" Poljoprivrednog fakulteta u Beogradu. Ispitivanje i praćenje ove sorte vršeno je u periodu 2000-2003. Od važnijih pokazatelja ispitivani su: prinos grožđa, broj grozdova po čokotu, masa grozda, sadržaj šećera u širi, sadržaj ukupnih kiselina u širi i procenat alkohola u vinu. Prinos grožđa je varirao od 2,446 - 6,566 kg/čokotu, masa grozda od 93,17 - 107,40 g, broj grozdova po čokotu je varirao od 20,63 - 39,86, sadržaj šećera u širi je varirao od 20,42 - 21,50%, sadržaj ukupnih kiselina u širi kretao se od 6,63 - 7,07 g/l, dok je sadržaj alkohola u vinu varirao od 10,91 - 11,91%.
