This experiment was conducted to investigate the relationship between storing condition of ‎potato seed and application of Giberellic acid (GA3) on quantitative traits and total yield of ‎potato seed tubers. The research was conducted at the Khorram dareh Agro‏ ‏‎- industry.‎ Three cultivars of potato with two methods of storage and three levels of GA3 (0, 5, 10 ‎ppm) in a factorial design with randomized complete blocks were cultivated. The five ppm of ‎GA3 with storage conditions number two had most effects on potato seed production. The ‎effects of storage conditions in treatments of five and 10 ppm of GA3 on producing amount of ‎main stem didn’t show any significant difference at one percent level. In total, "Marfona" had ‎the highest yield in the most treatment and we have obtained 3.71 kg/m2 on mean weight of ‎tubers from this cultivar.‎
