Ukrainian, Russian, and Byelorussian cultivars started growth earlier than standard cultivars, the earliest ones being ‘Byelorusska Slodkaya’, ‘Suita Kyevskaya’, ‘Kozatska’, and ‘Tchernetcha’, 9 days prior to the early cultivar ‘Ojebyn’. The aforementioned cultivars started blooming earlier by 5 days. The bushes of ‘Tchernetcha’ split strongly. Those of a Ukrainian cultivar ‘Novost Prikarpatya’ grew the strongest, the same referring to a standard cultivar ‘Titania’. The weakest growth was typical of ‘Malyshkha’, ‘Bagira’, ‘Basura’, and ‘Suita Kyevskaya’. The fruit of Ukrainian, Russian, and Beylorussian cultivars ripened much earlier than standard cultivars in the climatic conditions of Wielkopolska. The earliest ones were ‘Byelorusska Slodkaya’ and ‘Suita Kyevskaya’, whose harvest took place 1-3 weeks earlier than the standard early cultivar ‘Oyebyn’. The most fruitful within the initial 4 harvests was ‘Titania’, whose total yield was 22.26 kg per bush. The best yield came from ‘Katyusha’ and ‘Vernisage’, whose total yield during 4 years equaled 20.37 and 18.79 kg per bush respectively. The following Ukrainian cultivars: ‘Sanyuta’ (with an average fruit weight of 100 berries ranging from 135 to 151 g), ‘Kozatska’ (128-148 g respectively), ‘Tchorny Jemtchuk’ (119-139 g), and ‘Suita Kyevskaya’ (120-164 g) and, as a standard cultivar, ‘Ben Sarek’ (112-151 g respectively), were characterized by the most shapely fruit.
