Pomological properties of newly introduced red currant cultivars (Ribes rubrum L.)

Abstract

The obtained results show the pomological properties of six newly introduced red currant cultivars: Rovada, Red Poll, Rondom, Junifer, Makosta and Detvan in comparison to the cultivar standard - Industria (Heinemann's Rote Spatlese). The study was conducted in the collection orchard of red currant cultivars located in the nursery "Omega", the village of Mislodjin in the vicinity of Belgrade. The experiment was established in the spring of 2005. It included three replications, three bushes per plot, planted at the distance 3.0 x 1.0m. The study included some most important indicators of physical properties of the cluster and fruit, chemical composition of fruit, as well as, the sensory evaluation of fruit quality based on which ranking of cultivars according to their quality was established. Based on the analysis of physical properties of the cluster it can be concluded that the cultivar Red Poll was superior with regard to the cluster weight (15.75g), cluster length (10.38cm) and the number of berries per cluster (22.3). Also, that cultivar had the highest content of soluble solids (13.4%) and total acids (2.95%). The other tested newly introduced cultivars Rovada, Rondom and Detvan demonstrated higher values of physical cluster properties and the berry weight in comparison to the standard cultivar - Industria, that expressed better results with regard to the fruit chemical composition. Therefore, the mentioned four newly introduced cultivars, as well as, the standard cultivar, can be recommended for commercial growing under the agroecological conditions of the broader Belgrade area. .

Rad prikazuje rezultate ispitivanja pomoloških osobina šest novointrodukovanih sorti crvene ribizle: Rovada, Red Poll, Rondom, Junifer, Makosta i Detvan. Kao standard je korišćena sorta Industria (Heinemann's Rote Spatlese). Proučavanja su vršena u kolekcionom zasadu crvene ribizle na imanju rasadnika "Omega" u selu Mislođin, u periodu 2005-2006. Ogledom su obuhvaćeni važniji pokazatelji fizičkih osobina grozda i ploda, hemijski sastav ploda, kao i senzorička ocena kvaliteta ploda, na osnovu koje je izvršeno rangiranje sorti po kvalitetu. Analizirajući dobijene rezultate, možemo konstatovati da je sorta Red Poll u pogledu parametara fizičkih osobina grozda ispoljila superiornost među ispitivanim novointrodukovanim sortama, kao i u odnosu na sortu standard - Industria, koja je manifestovala statistički veoma značajno niže vrednosti mase grozda (5,35 g) i dužine grozda (6,30 cm) u poređenju sa pet ispitivanih novointrodukovanih sorti. Najveći sadržaj rastvorljive suve materije (13,4 %) i ukupnih kiselina (2,95%) registrovan je kod sorte Red Poll, što pored odličnih fizičkih osobina grozda, ukazuje i na visok kvalitet ploda pomenute sorte. Pored ove sorte, bolje rezultate u pogledu većine analiziranih parametara ispoljile su i sorte Rovada, Rondom i Detvan u odnosu na sortu standard (Industria), koja zahvaljujući pogodnom biohemijskom sastavu ploda i dalje ostaje vodeća industrijska sorta. .
