This research was carried out in greenhouse of Mohaghegh Ardabili University by using split plot experiment basis of completely randomized block design. In this project ,obtained micro tuber from healthy laboratory plantlets of potato (private section) were planted in greenhouse condition during 2006.Microtubers were sprouted (amount of 0.5 cm) at the planting time and they were not necessary for presprouting of planted micro tubers. In this research the cultivars were used as main plot in 2 levels (Savalan and Agria) and micro tuber sizes (weight) were used as sub plot in 6 levels of 50 mg, 50-100 mg ,100- 150 mg,150-200 mg,200-250 mg and one gr tuber size (check) .Agronomic practices were uniformity used for all treatments during planting and plant growth and development stages. The studied agronomic characters such as wet tuber yield per unit area and hectare, emergence percent ,flowering date, stolon and tuber initiation dates, number of tuber per plant, number of main stem per plant, mean stem diameter and stem height were recorded during plant growth and developments. Analysis of variance was done by using the SAS statistical software and the comparison of treatments mean of mentioned above characters were done on the basis of LSD 5%.Savalan in 200-250 mg with production of 4.755 kg tuber per m2 relative to compare with Agria and other factors of micro tuber weight levels had better conditions between 2 studied cultivars. There were significantly differences between main effect of cultivars in analysis of variance table and all of studied characters were better in Savalan, by contrast to Agria. So it caused the very significantly increasing of wet tuber yield in Savalan.
