and Aleksići. The trial was arranged in a randomized complete block design with three replications. The following parameters were analyzed: tuber weight (g), plant height (cm), stem number/plant, average stem thickness (cm), green mass yield/plant (kg), and dry mass yield/plant (kg). Average tuber weight ranged from 36.7 g (Bosna) to 61.0 g (Lazarevo). Plant height ranged from 1.55 m (Lazarevo) to 2.20 m (Aleksići). Stem number/plant varied from 2.2 (Aleksici) to 5.3 (Modrica). Stem thicknesswas between 1.24 cm (Bosna) and 2.11 cm (Aleksići). The population Bosna had the lowest average yield of green mass and dry mass yield/plant, while the highest mean value had population Aleksići. Broad sense heritability varied from 34.66% (plant height) to 50.99% (dry mass yield/plant). Highly significant positive correlations between plant height and stem thickness (r = 0.874), stem thickness and green mass yield (r = 0.919), stem thickness and dry mass yield (r = 0.902) were established. Jerusalem artichoke populations were clustered into two groups, and the first group was composed of two subgroups .The results of these studies will allow choice of Jerusalem 46
