New table potato varieties

In 1998 and 1999 respectively a selection of mid-early to mid-late table potato varieties have been assessed within the main trials (7 locations) throughout Switzerland. The experiments were conducted within the framework of the swisspatat working group for potato cultivars, by the two Swiss Federal Agricultural Research Stations Zurich-Reckenholz and Changins. For the varieties Victoria and Appell, results concerning agronomic characteristics, disease resistance and food use possibilities are presented. Victoria and Appell have been admitted to the Swiss national list for potato cultivars. Appell, in particular, has been further introduced in the recommended list for potato cultivars in 2001, due to a high resistance against late blight, a low susceptibility for tuber damages, a long dormancy and thus an excellent storability. Appell is well appropriated for integrated and organic potato production. In general, the introduction of new potato varieties may help to provide consumers with environmentally friendly produced potatoes of high quality. However, there is a need for special efforts of all market participants in the promotion of this promising variety
