In order to find the most effective concentration of 6-Banzilamino purine (BAP) and cycocel (CCC) on microtuber production of two potato cultivars under tissue culture conditions, a factorial experiment was carried out with randomized compelete design with 4 replications. Four levels of BAP (0, 5, 10 and 15 mg L-1) and four levels of CCC (0, 250, 500 and 1000 mg L-1) were applied on two potato cultivares (Sante and Arinda). Results showed that the best cultivar for microtuber production was Arinda and the best plant growth regulator combination regarding to microtuber number was 10 mg L-1 BAP+250 mg L-1 CCC. Although, the highest microtuber yield achived at 5 mg L-1 BAP without CCC. Tuber dry weight and tuber diameter were reached to the highest levels at 10 mg L-1 BAP without CCC. On the other hand, higher microtuber number, yield, and the larger microtuber, acompanied with decrease of shoot and root length were obtained with BAP and CCC application.
