Abstract


The sprouts of potato variety Solanum tuberosum L. cv. Desiree were used as explants to regenerate in vitro plantlets. The best regenerated shoots were treated for their growth in sugar solution with different concentration (2.5, 5, 10 & 12 g/L) in MS Medium with 0 and 2 mg/L Benzyl amino Purine (BAP) concentration to examine tuber induction during 1st, 2nd and 3rd week. The results regarding number of tubers, the highest number of tubers were recorded in media containing 2 mg BAP+10.0 g and 12.0 g sugar concentration, i.e., 8.66 and 9.00 tubers per plant and tuber weight in this study indicated that the highest weight of tubers were in the media containing 2 mg BAP+10.0 g and 12.0 g sugar concentration produced tubers of 94.80 and 91.73 mg/plant, respectively.
