Qualitative indicators of redcurrant varieties (Ribes rubrum L.) selected by the Professor V.L. Symyrenko Department of Horticulture of NULES of Ukraine

Abstract

This study presents the findings on the qualitative indicators of seven varieties of redcurrant (Ribes rubrum L.), five of which are selected by the Professor V.L. Symyrenko Department of Horticulture of NULES of Ukraine. The largest average weight of berries had the varieties 'Buzhanska' (0.58 g) and 'Polyana Holosiivska' (0.59 g). These varieties also stand out among others in terms of maximum berry weight. In certain years of research, the fruits of 'Buzhanska' weighed 1.05 g. The 'Lebidka' variety had the largest cluster weight (6.98 g) due to the large number of berries in it (17 pcs.). The uniformity of berries in the cluster of the studied varieties is average (from 63 to 73% depending on the variety). The highest yields per bush were achieved by 'Buzhanska' (4.20 kg/bush), 'Kyianochka' (4.42 kg/bush) and 'Polyana Holosiivska' (4.0 kg/bush). The varieties 'Jonkheer van Tets' (c.), 'Polyana Holosiivska', 'Buzhanska' and 'Snizhanka' are rich in vitamin C. The highest dry soluble solids content was found in the 'Lebidka' variety (12.94%). The most sugars in the fruit were accumulated by the varieties 'Snizhanka' (5.40%), 'Buzhanska' (5.23%) and 'Malva' (5.13%). The white-fruited varieties 'Snizhanka' and 'Lebidka' are particularly notable for their dessert flavour, as they have the best sugar to total acidity ratio (TAR) among the varieties studied – 4 and 3, respectively, and the highest flavour score (9 points)
