The objective of this study was to analyze the variability and mutual dependence of the tuber weigh per plant, tuber number per plant, average tuber weight and total sugars content in the tubers of 20 Jerusalem artichoke genotypes included in a varietal trial conducted in the period 1994-2008. The variability of tuber weight per plant, tuber number per plant and average tuber weight was significantly affected by environmental conditions, while the total sugars content in the tubers depended primarily on the genotype. As the tuber weight per plant increased, the content of total sugars in the tubers decreased. Maximum tuber weight per plant was achieved with the genotype BT-4 and highest content of total sugars in tubers were found in the genotypes Violet Rennes, UKR 5/82 and Topianca.
