Abstract :

This research was conducted to evaluate mini-tubers production potential in micro-tuber different potato cultivars under greenhouse conditions in Ardabil Agricultural and Natural Resources Research Station during 2010. Micro-tubers less than 1g of eight potato cultivars (Satina, Caesar, Marfona, Luta, Agria, Markies, Hermes and Savalan) were cultured on completely randomized design with three replications. The micro-tubers were planted in Biolan and Punch bed planting to volume ratio of 1:1 in plastic as pots 10×10 cm. Analysis of variance for measured traits showed that potato cultivars in all of traits had significant difference. The maximum mini-tuber number per m2 belonged to Agria cultivar; mini-tuber weight per m2 and mini-tuber size average belonged to Savalan cultivar; mini-tuber number and weight higher than 10 g belonged to Savalan and Satina cultivars; mini-tuber number and weight between 7-10 g belonged to Agria and Satina cultivars.
