About 70 % of the registered carrot varieties in the European Union are hybrid varieties. In organic farming the use of hybrid varieties is discussed controversially. Due to the recent discussions on hybrid varieties Biohof Adamah, producing and marketing organic vegetables, was looking forward to find an open pollinated carrot variety which is well adapted to the site of production and is consistent with the requirements of the farm. Therefore, a field experiment with 17 open pollinating varieties and one check hybrid variety was carried out. Besides agronomic traits several quality aspects were investigated by lab analyses and a hedonistic sensory test. The hybrid variety Maestro F1 showed the best performance in regard to economic traits but revealed deficits in nitrate level and the sensory test after four month storage. Three open pollinated varieties, i.e. N2 Milan, N2 Fynn and N2 Beate, revealed acceptable performance concerning economically important traits, e.g. marketable yield, homogeneity etc., and excellent inner quality, e.g. low nitrate concentration, high popularity in sensory tests in regard to taste and flavour. It is concluded that there exists enough variability in the currently available open pollinated varieties for the economic production of organic carrots. Furthermore, the positively selected non-hybrid varieties can form the basis for an open pollinated, farm and site specific selection program.
