AbstractIn this study, carried out in 2017, the aim of the experiment was to compare new cultivars of celeriac (Apium graveolens var. rapaceum) that were not yet registered on the EU list. Yield as well as chemical composition of tubers and leaves were determined. The yield of tubers ranged from 31.2 t ha-1 (‘Kompakt’) to 52.6 t ha-1 (‘Diamant’), and leaf biomass ranged from 26.3 t ha-1 (‘NOV2231 AG’) to 54.7 t ha-1 (‘Phoenix’). The new cultivars – ‘Phoenix’ and ‘Kompakt’ – were characterized by the highest dry weight of tubers (15.5 and 14.0%, respectively) in relation to the well-known cultivars ‘Diamant’ and ‘Brilliant’ (10.3 and 10.6%, respectively). A significantly higher amount of essential oils was found in the leaves of the new cultivar ‘NOV2231 AG’ (0.95 cm3 100 g-1 DW) compared to ‘Diamant’, ‘Brilliant’ and ‘Phoenix’. The highest total phenolic content was determined in tubers of the new cultivars ‘Phoenix’ and ‘Kompakt’ (0.73 and 0.69 mg GAE g-1 FW, respectively). The lowest concentrations of Ca, S, Mn, and Sr, Cd and Ba were determined in the leaves of ‘NOV2231 AG’. In general, all the new cultivars tested (with the exception of ‘AG1101’) had a lower tuber weight but a significantly higher concentration of flavonoids and total phenols in the roots in relation to the well-known cultivars ‘Brilliant’ and ‘Diamant’. Except for ‘NOV2231 AG’, the tubers of the new cultivars were characterized by a higher dry mass compared to ‘Brilliant’ and ‘Diamant’. The leaves of the new cultivars were notable for the lowest Ca and Mg content in comparison with the well-known commercial cultivars.
