The golden nematode, Globodera rostochiensis which was reported from Hamadan in 2008, is one of the most important pests of potatoe world wide which causes serious yield reduction. Damage to plant occures with invasion of the roots and production of specialized feeding cells. Since the nematode is fairly new for the region, its pathogenicity needs to be monitored on potato cultivars. In a preliminary test, the relation between nematode and a common potato cultivar in Hamadan was studied. Marfona was planted in microplots infested with 0.05, 4, 9 and 15 eggs and J2/g soil and weights of plant growth parameters and final nematode density were taken after 75 days. As nematode density increased at planting, plant and tuber weights decreased. Nematode reproduction increased with increasing nematode population at planting. The highest final nematode density occurred at highest initial population.
