          Abstract

          Na bananeira ocorrem variações somaclonais em taxa muito superior ao que se observa na maioria das outras culturas, provavelmente em função da instabilidade mitótica. Objetivou-se com o presente trabalho avaliar clones de bananeira Cavendish coletados em diferentes locais. Os clones Grande Naine (G.N. Taperão, G.N. Rossete, G.N. Williams, G.N. Magário, G.N. SC-074) e Nanicão (N. IAC Abóbora Verde, N. Rossete, N. SC-0008 e N. SC-063) coletados em São Paulo, Santa Catarina e Bahia foram avaliados no Lote 54-P da Thelo Produção Agropecuária (Grupo Plena), no Projeto Jaíba, Etapa 1, no município de Matias Cardoso-MG. Avaliaram-se os caracteres altura da planta, circunferência do pseudocaule, número de folhas vivas no florescimento e na colheita, número de brotos, peso do cacho e das pencas, número de frutos e de pencas por cacho, comprimento e circunferência do fruto e número de dias do plantio ao florescimento e à colheita. Observou-se grande similaridade nas características dos clones. No entanto, os resultados obtidos permitem a recomendação dos clones N. IAC Abóbora Verde e G.N. Williams.

          Translated abstract

          Somaclonal variations occur in bananas at greater rates compared to other crops, probably due to mitotic instability. The objective of the present research was to evaluate Cavendish banana clones collected from different sites. The 'Grand Naine' clones (G.N. Taperão, G.N. Rossete, G.N. Williams, G.N. Magário, G.N. SC-074) and 'Nanicão' (N. IAC Abóbora Verde, N. Rossete, N. SC-0008 and N. SC-063) collected from the states of São Paulo, Santa Catarina and Bahia, were evaluated at the Station 54-P of the Thelo Agricultural Production (Plena Group), in the Jaíba Project, Stage 1, in the city of Matias Cardoso-MG. The characteristics of the plant as height and pseudostem circumference, number of live leaves at flowering and harvesting, number of shoots, weight of bunch and hand, number of fruits and hands per bunch, fruit length and circumference, and the number of days from planting to flowering and harvest, were evaluated. Great similarity among the clone characteristics was observed. However, the results allowed to recommend the following clones: N. IAC Abóbora Verde and G.N. Williams.
