At SCDVV Murfatlar, in the period 2018 – 2022, a study was carried out on 5 clonal elites of the 'Bican roz' cultivar, selected from existing trunks in the ampelographic collection of the research station. In all 5 years of studies and observations, the clonal elite 80/10/6 was superior to the other elites, being approved under the name Bican roz 6 Mf in 2022, following testing at ISTIS (State Institute for Testing and Registration Varieties).
During the research period, average annual temperatures were 2-3°C higher in comparison with the multiannual average, while precipitation values were situated below the multiannual average (406 mm, average during the study period, compared to 522.6 mm, the multiannual average).
For all 5 clonal elites, the agrobiological properties, as well as the technological and agroeconomic characteristics were compared to those of the original variety. Bican roz 6 Mf is a table grape clone with high growth vigor and 79% fertility. It is a productive clone, with an average grape bunch weight of 714 g, compared to 403 g, the average grape weight for the original variety, and with yields of 10.76 kg/trunk, respectively 24 t/ha and commodity production of 75 – 80%.
