Agrobiological and technological characteristics of five black wine varieties of the Proles occidentalis group in the vineyard district grocka

Abstract

On the basic of three-year testing of five black wine varieties of the Prolec occidentalis group, grown in the vineyard district of Grocka, the following conclusions can be made: 1. High yield of grapes exhibited variety game black the great, while varieties merlot, Burgundac black and cabernet Souvignon had smaller yield of grapes, and the Caberne franc variety had the smallest yield of grapes. 2. The biggest cluster masshad variety cabernet franc the great, followed by varieties merlot, game black and cabernet Souvignon, while smallest cluster mass had the Burgundac black variety. 3. Biggest berry mass had the cabernet franc variety, while smaller berry mass had varieties merlot, cabernet Souvignon and game black, and smallest berry mass had the Burgundac black variety. 4. Biggest sugar content in must had the Burgundac black variety, while cabernet Souvignon, cabernet franc and merlot varieties had less sugar, and game black the great variety had the smallest sugar content. 5.

U radu su prikazani rezultati proučavanja važnijih agrobioloških i privredno tehnoloških karakteristika pet crnih vinskih sorti grupe Proles occidentalis: Burgundac crni, Game crni, Kaberne sovinjon, Kaberne fran i Merlo u uslovima gročanskog vinogorja. Na osnovu rezultata ispitivanja može se zaključiti da su ove sorte u agroekološkim uslovima gročanskog vinogorja ispoljile stabilnu rodnost sa zadovoljavajućim kvalitetom grožđa. Ispitivanje je obavljeno u ampelografskoj kolekciji "Radmilovac" Poljoprivrednog fakulteta u Zemunu u periodu od 1992-1994. godine.
