In order to evaluate the possibility of the use of hybrid mini tubers in potato production, nine TPS families including Desiree×Payezeh, Caesar×Payezeh, Caesar×Aula, Aula×Desiree and Draga ×esiree Hybrids and Desiree, Aula and Daiezer open pollinated populations with five Clonally varieties: including Aula, Caesar , Desiree, Draga, Astrix were compared in an augomented design based on completely randomized blocks. Agronomic traits such as plant yield, plant height, number of stem in plant and number of tubers in plant were noted. The results showed that there are significant differences among treatments for plant height, number of stems and number of tubers and yield. Desiree variety with 557gr per plant yield and then Desiree×Payezeh and Caesar×Payezeh hybrids with 549 and 445gr per plant yield respectively had the higher yield. The least yield was of Aula×Desiree and Payezeh×Aula hybrids. The Desiree×Payezeh hybrid had the highest and the Draga variety and open pollinated Caesar had the lowest height respectively. Astrix and Desiree varieties with average stem number of 4.5 and 4.4 had the highest number of stems. Concerning the number of tubers, Desiree×Payezeh Hybrid with average 20 tubers and Draga with average 4.6 tubers had the highest and lowest number of tubers respectively. The study of correlation coefficient between traits showed a significant relationship between yield plant with the numbers of stem and height of the plant, and also the plant height showed a significant relationship at 5% probability level with the number of tubers and stems.
