Petra : Sorte šljive (Prunus domestica L.)

Abstract

Nova sorta šljive Petra je priznata Rešenjem Ministarstva polјoprivrede, šumarstva i vodoprivrede Republike Srbije br. 320-04-00840/2011-11 od 03.04.2018. godine. Nastala je planskom hibridizacijom, ukrštanjem sorti Stenlej (Stanley) i Opal. Stablo sorte Petra je srednje bujnosti sa krošnjom srednje gustine. Tolerantna je na virus šarke šljive (Plum Pox Virus). U uslovima prirodnog zaražavanja ispoljava veoma blage simptome karakteristične za prouzrokovače ekonomski najznačajnijih gljivičnih bolesti šljive. Sorte Petra cveta pozno, istovremeno sa sortom Stanley. Rano stupa u fazu pune rodnosti i ima veliki potencijal rodnosti. Plod je izduženo-ovalnog oblika. Prosečna masa ploda je 26 g, pokožica je tamnoplave boje sa obilnim pepeljkom. Mezokarp je tamnožute boje, čvrst, aromatičan i ukusan sa prosečno 21,50% rastvorljivih suvih materija. Plodovi se mogu koristiti za potrošnju u svežem stanju, kao i za različite vidove prerade. Vreme sazrevanja plodova je veoma kasno, u drugoj dekadi septembra.

The new plum cultivar "Petra" was named and released by the Ministry of Agriculture, Forestry, and Water Management of the Republic of Serbia (confirmation No. 320-04-00840/2011-11; April 3, 2018). It was developed through planned hybridization, by crossing the "Stanley" and "Opal" cultivars. The "Petra" plum tree is of medium vigor with a moderately dense canopy. It is tolerant to the sharka virus (Plum Pox Virus) and exhibits very mild symptoms characteristic of economically significant fungal diseases under natural infection conditions. "Petra" plum flowers late, at the same time as the "Stanley". It enters full fruit-bearing phase early and has high fruit-bearing potential. The fruit is elongated-oval in shape with an average weight of 26 g. The fruit skin is dark blue with abundant bloom. The mesocarp is dark yellow, firm, aromatic, and tasty, with an average of 21.50% soluble solids content. The fruits can be used for fresh consumption and various processing purposes. The fruit ripens very late, in the second decade of September.
