In vitro sweet potato (Ipomoea batatas (L.) Lam.) was evaluated as to its ability to regenerate into plantlets and micropropagation. Apical meristems were inoculated on MS medium supplemented altematively with ANA + BAP; ANA + KIN + GA3; and ANA + BAP + GA3. The cultivars RC 1.8, MFT (Mãe-de-Família També), TR 3, 473 and Arroba led plantlets with similar height but different regeneration ratio. The supplementation with 0.01 mg/l of ANA plus 1.0 mg/l of BAP was indicated for Arroba and MFT; however, for TR 3,473 and RC 1.8, the supplementation with 0.005 mg/l ANA + 0.5 mg/l BAP + 0.25 mg/l AG3 was recommended. Plantlets were propagated through nodal segments using MS medium with 1.0 mg/l of GA3. Differences between cultivars were not observed.
