Com o objetivo de desenvolver um procedimento eficiente para a produção de mudas de bananeiras tetraplóides (Musa sp. cv. FHIA-01, grupo AAAB) estudou-se o efeito do clone no desenvolvimento in vitro dos explantes e as taxas de contaminação, multiplicação e nível de oxidação em meios de cultura contendo cinco concentrações de BAP. Na fase de introdução in vitro dos explantes, foi observada elevada taxa de contaminação (22,32%), causada, principalmente, por bactérias. No entanto, os níveis de contaminação decresceram na seqüência dos subcultivos, tendo sido de 1,07% no oitavo subcultivo. As maiores taxas de multiplicação foram obtidas no meio de cultura MS com 4,0 mg L-1 de BAP, em média de 2,65 plântulas por subcultivo, possibilitando a produção estimada de 584 plântulas de FHIA-01 por explante inicial no sexto e 3451 no oitavo subcultivo. Em função do clone, houve a produção estimada de 305 a 4497 plântulas por explante inicial, após oito subculturas. A eficiência de aclimatização das plântulas foi de 94%, não sendo encontrados variantes somaclonais em condições de casa-de-vegetação. The objective of the present work was to establish an efficient procedure for the in vitro production of tetraploid banana plantlets (Musa sp. cv. FHIA-01, AAAB group). The cloning effect on the in vitro development of the explants, the rates of contamination and multiplication, and the level of oxidation in culture media with five benzylaminopurine (BAP) concentrations were studied. In the phase of in vitro introduction of explants, a high level of contamination (22.32%), caused mainly by bacteria, was observed. However, the degree of contamination decreased along the subcultures, reaching 1.07% in the eighth subculture. Higher multiplication rates were obtained, averaging 2.65 per subculture, on the MS media supplemented with 4.0 mg L-1 BAP, leading to an estimated production of 584 and 3451 plantlets/initial explant after the 6th and 8th subculture, respectively. A pronounced effect of the cloning on multiplication was observed. Acclimatization efficiency of plantlets was 94%. Somaclonal variations were not observed among in vitro micropropagated plantlets under greenhouse conditions
