Examination of heritability of yield and yield components of autochthonous populations of Jerusalem artichoke was conducted in the experimental field of the Agricultural Institute in Banja Luka during 2015 and 2016. The trials were set up in four replications with ten populations of Jerusalem artichoke in the late October 2014. During the study, the following parameters were observed: plant height, number of stems per plant/clone, stem thickness and dry matter yield per plant/clone. Population Razboj had the highest yield of dry matter per plant/clone. In the first year, the population of Irić bašta had the largest number of stems per plant/clone. Broad sense heritability for plant height and number of stems per plant/clone indicates intermediate hereditary traits. A significant positive genetic correlation between yield of dry matter and plant height was determined.
