ln order to evaluation the possibility of true potato seed application for potato production, An experiment conducted with six true potato seed families includeing three open pollination Aula, Kaizer and Dessire cultivars and three hybrid families from the crosses of paeizeh x Dessire, paeizeh x Kaizer and Aula x Kaizer in Ardebil Azad University Agriculture research station. Some agronomic traits such as seedling stability, Plant hight, number of stems, plant vigor, number of tubers, yield and tuber dry matter were measured. The results of ANOVA showed that there is no significant differences among families in terms of plant hight, number of stems, seedling stability and dry matter, however differences in number of tubers, tubers weight and plant vigor were significant. Paeizeh x Dessire, Payezeh x Kaizer with average of 21.3 and 20.4 tubers per plant had the highest and Kaizer and Dczireh open pollination with average of 8 and 6.5 had the lowest number of tubers per plant respectively. Also ranks of plant vigor in Paeizeh xDessirc hybrid with the average of 3 and open pollination of Dessire with the average of l.7 were the highest and lowest amounts respectively. Also, hybrid families were superiar than open polliantions in term of yield, So that Paeizeh =Desstre with 20460 kg/ha was the highest yielding and Dessire open pollination with 6060 kg/ha was the least yielding families. Analysis of correlation coefficient showed that there are significant positive relations between yield and agronomic traits includeing number of stems, number of tubers, plant vigor, seedling success and plant hight.
