Abstract

Sorta 'Portugalka' je nastala s križanjem sort 'Mala modrina' in 'Zeleni silvanec' na območju današnje Slovenije. 'Portugalka' je danes razširjena tudi v Avstriji, Nemčiji, Franciji, na Madžarskem. V Sloveniji jo trenutno gojijo na približno 13,0 ha, od tega 11,7 ha v vinorodni deželi Posavje, preostalih 1,3 ha pa v vinorodni deželi Podravje. Sorta 'Portugalka' se je najbolj ohranila v vinorodnem okolišu Bela krajina, kjer je na 7,2 ha zasajenih 30496 trt. Sorta ni občutljiva na tip tal, dobro prenaša sušne razmere in se jo priporoča saditi na južne lege. Občutljiva je na peronosporo (Plasmopara viticola Berl. & de Toni) in oidij (Uncinula necator (Schwein) Burrill). Za sorto 'Portugalka' se priporoča gojitvena oblika enojni guyot. Sorto uvrščajo med masovnice. V fenofazi začetek zorenja se priporoča 40-50 % redčenje grozdja, ki prispeva h kakovostnejšemu grozdju in pridelavi vrhunskega vina. Tehnološko zrelost grozdja lahko opišemo s povprečno vrednostjo skupnega sladkorja 75 °Oe, skupnih kislin 5,87 g/l in pH 3,36. Vino ima povprečno vsebnost alkohola 11,0 vol. %, vsebnost skupnih kislin 6,46 g/l in pH 3,65. 'Portugalka' se prideluje kot mlado sortno vino, ki se uvršča v kakovostni razred, najpogosteje pa se vino portugalka meša v zvrsti.

Secondary title: ǂThe ǂampelographic characteristics, viticultural and winemaking practices and grape and wine quality of the grapevine (Vitis vinifera L.) 'Portugieser Blauer' variety
Secondary abstract: The 'Portugalka' variety (Blauer Portugieser) was created by crossing the varieties 'Mala modrina' and 'Zeleni silvanec' in the area of today's Slovenia. It is spread also in Austria, Germany, France, Hungary. In Slovenia it is currently grown at about 13,0 hectares, out of which 11,7 hectares are in the wine-growing region of Posavje, and the remaining 1,3 hectares in the wine-growing region of Podravje. The 'Portugalka' variety has been most preserved in the wine-growing region of Bela krajina, where on 7,2 hectares there are 30496 vines planted. The variety is not susceptible to the soil type, it tolerates drought well and is recommended to be planted in the south-facing sites. It is sensitive to peronospora (Plasmopara viticola Berl. et de Toni) and oidium (Uncinula necator (Schwein) Burrill). For the 'Portugalka' variety a single guyot training system is recommended. The variety produces high yields of grapes. In the phenological stage the beginning of ripening 40-50% thinning of grapes is recommended, which contributes to a better grapes quality and production of premium wine. The technological maturity of the grapes can be described with an average sugar value of 75 °Oe, total acids content amounting to 5,87 g/l and pH 3,36. The wine has an average of about 11,0 vol. % alcohol, total acids 6,46 g/l and pH 3,65. The 'Portugalka' variety is produced as a young wine of a quality class, but most often it is included in blends.
