Abstract :Broad-sense heritability insert ignore into journalissuearticles values(H); values of some quantitative traits in a potato population comprising 21 genotypes grown at Bornova, Izmir, Turkey during the 2013 and 2014 growing seasons were estimated by using the variance components analysis method. Based on the combined analysis of variance performed over two years, the following moderate to high level H values were found for plant height insert ignore into journalissuearticles values(0.77);, leaf width insert ignore into journalissuearticles values(0.69);, leaf length insert ignore into journalissuearticles values(0.71);, single tuber weight insert ignore into journalissuearticles values(0.74);, plant yield insert ignore into journalissuearticles values(0.60); and starch content insert ignore into journalissuearticles values(0.87);.The expected genetic advance based on the selection of 25 % upper part was 8.2 cm for plant height; 0.5 for tuber number; 18.5 g for single tuber weight; 150.8 g for plant yield; 2.2 kg for plot yield and 1.9 % for starch content
