Parsnip (Pastinaca sativa L.) is one of the few cultivated plants domesticated in Europe. The crop is underutilised and the number of available varieties is small in Central Europe. On-farm management of genetic resources can be an important means to increase infraspecific diversity, and to improve the quality of crops. In the present experiment quality-improvement by progeny selection on-farm was investigated. In a first step parsnips were selected for organoleptic quality by a technique that allows to harvest seeds from the plant tested. In a second step, progenies of positive- and negative-selected plants were compared with the original population. The experiment was carried out with the varieties Aromata (2006) and White King (2008) in biodynamic management. Organoleptic quality was determined according to a key developed for parsnip. Sugar contents were determined. Organoleptic selection significantly improved sweetness and flavour and can be recommended. However, selection was not efficient to improve texture.
