Abstract Organic and conventional growers require potato varieties that give reliable and stable yields under low nitrogen input conditions. However, breeders lack suitable selection criteria to select for such varieties. In this research we analysed genetic variation of relevant crop characteristics and physiological processes associated with nitrogen efficiency under low nitrogen input. The aim is to identify crop traits that reflect variation in the ability to deal with low availability of nitrogen and to transform these traits into practical selection criteria. In 2008 and 2009 field trials were conducted on an organic site (sandy soil) and on a conventionally managed site (clay soil). In 2010 and 2011, both trial fields were on an organic farm (a sandy soil and a clay soil).
