Biological-pomological properties of some red and white currant cultivars and selections

Abstract

Over a five-year period (1992-1997), the major properties of four red and four white currants were studied under the agroecological conditions of Cacak. The planting was set up at the Ljubic locality belonging to the Fruit and Grape Research Centre in Cacak. The trial included the following cultivars: red currant - 'Bo 123*', 'Detvan', 'Tatran' and 'Bo 80'; white currant - 'Bo 71', 'Primus', 'Blanka' and 'White Versailles'. The phenology of flowering and ripening, strig mass, number of berries per strig, percentage of berries set, berry mass and dimensions, number of seeds per berry, stalk mass, soluble solids and yield per bush and per hectare were assessed. The earliest to flower was cv. 'Detvan' and the last cv. 'Blanka'. The earliest ripening time was recorded with cv. 'Detvan' and the latest with selection 'Bo 71'. The largest strig among red and white cultivars belonged to cv. 'Tatran' and cv. 'Blanka', respectively. They also had the largest berries. The highest number of berries per strig among red and white cultivars came from cvs. 'Tatran' and 'Blanka'. 'Bo 123' had the highest percentage of berries set. Selection 'Bo 71' had the highest content of soluble solids. The largest yield among red and white cultivars was observed in cultivars 'Bo 123' and 'Blanka', respectively.
