Several nutritive values for tubers of 114 Jerusalem artichoke (Helianthus tuberosus) populations were evaluated during 2006. The used material is a part of wild sunflower species collection at the Institute of Field and Vegetable Crops and it is situated in Rimski Sancevi, Novi Sad (Serbia). The samples were analyzed as fresh tubers on Venema automatic laboratory for alpha amino nitrogen, sodium and potassium content. Total sugar content was determined as the brix value on a refractometer. Total nitrogen was determined by Kjeldahl method on dried samples. Significant variability was found for all analyzed traits. The obtained results suggest that selection of populations with appropriate nutritive values is possible.
