This research were conducted to evaluate micro-tubers production potential in plantlets different potato cultivars under in vitro condition in the tissue culture laboratory of Bahparvar Sabalan Company during 2013. The plantlets of five potato cultivars (Agria, Sante, Marfona, Savalan and Caesar) from meristem culture under in vitro condition by single nod cuttings method were amplified and from these plantlets were used to production micro-tubers. Analysis of variance for measured traits showed that potato cultivars in micro-tuber number, weight and diameter per plantlet, number of leave per plantlet and plantlet height had significant difference. The maximum of micro-tuber diameter per plantlet belonged to Marfona and Caesar cultivars, micro-tuber weight per plantlet belonged to Sante and Marfona cultivars, micro-tuber number per plantlet belonged to Sante, Marfona, Agria and Savalan cultivars, leave number per plantlet belonged to Sante, Savalan, Marfona and Caesar cultivars and plantlet height belonged to Caesar, Savalan and Marfona cultivars were. Linear correlation coefficients between traits showed that micro-tuber weight produced per plantlet with micro-tuber number per plantlet and number of leave per plantlet, and micro-tuber diameter with number of leave per plantlet had significant positive relationship. Based on the results of cluster analysis, the second group with Sante, savalan, Caesar and Marfona cultivars were selected the better cultivars.
