Dunavski rubin: A new indeterminate tomato cultivar

Abstract

Dunavski rubin is a medium early indeterminate cultivar with large fruits and average fruit weight of 180 g. It was developed by crossing cultivars Korona and Saint Pierre. Hybrid material was grown by using the pedigree method. Phenotypically uniform line V9 was selected and submitted to the Varietal Release Committee of the Republic of Serbia. Cultivar was released in 2014 by the Decision of Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia under no. 320-04-1871/2/2013-11. Dunavski rubin represents successful combination of genes responsible for high fertility rate and fruit quality. Fruits of Dunavski rubin cultivar have high percentage of dry matter (6.30%), high level of lycopene (106.7 mg/100 g), and excellent total acidity (0.39%). Vitamin C content is 52.7 mg/100 g, while total sugars amount to 5.71%. High K content (1520 mg/kg) and low Na content (79.8 mg/kg) is what distinguishes this cultivar from the others. Comparing with other cultivars trough three year field experiments, it was concluded that Dunavski rubin is a cultivar intended for fresh consumption due to a long fruit-bearing period, but is also an excellent raw material for processing due to its high quality fruit. All of the above mentioned classifies Dunavski rubin as an enhancer in technological processing of tomato.

Sorta Dunavski rubin je srednje rana indeterminantna sorta, krupnih plodova, prosečne mase 180 g. Nastala je ukrštanjem sorti Korona i Saint Pierre. Hibridni materijal je uzgajan po pedigre metodi. Fenotipski ujednačena linija V9 je odabrana i prijavljena Komisiji za priznavanje sorti. Sorta je registrovana 2014. godine rešenjem Ministarstva poljoprivrede, šumarstva i vodoprivrede Republike Srbije pod brojem 320-04-1871/2/2013-11. Dunavski rubin predstavlja uspešnu kombinaciju gena odgovornih za visok potencijal rodnosti i visok kvalitet ploda. Plodovi Dunavskog rubina imaju visok procenat suve materije od 6.30, visok nivo likopena od 106.7 mg/100 g i odličnu ukupnu kiselost od 0.39%. Sadržaj vitamina C iznosi 52.70 mg/100 g , dok ukupni šećeri čine 5.71%. Visok sadržaj K od 1520 mg/kg i nizak sadržaj Na od 79.8 mg/kg je ono što ovu sortu izdvaja od drugih. Na osnovu trogodišnjih poljskih ogleda i poređenja sa drugim sortama utvrđeno je da je Dunavski rubin pogodan za svežu potrošnju zbog dugog perioda plodonošenja ali je i odlična sirovina za preradu zbog visokog kvaliteta ploda koji je svrstavaju u red poboljšivača u tehnološkom procesu prerade paradajza.
