‘VTP Hayashi’: Nova cultivar do subgrupo Prata

O objetivo deste estudo foi descrever as principais características de desenvolvimento, produção e pós-colheita da nova cultivar do subgrupo Prata, a VTP Hayashi, mutação natural originada da cv. SCS451 Catarina. As plantas da VTP Hayashi apresentaram altura e diâmetro do pseudocaule maiores, e as frutas são mais longas, pesadas e uniformes no cacho, características que diferem da SCS451 Catarina. Os ciclos de desenvolvimento e de produção e a suscetibilidade às doenças fúngicas assemelham-se aos da cv. SCS451 Catarina. No estádio 6 de maturação, apresentou médias dos teores de sólidos solúveis de 28,1ºBrix e de acidez titulável de 0,69% de ácido málico, superior à SCS451 Catarina. A seleção desta cultivar foi devido ao posicionamento da inflorescência no sentido vertical, conferindo melhor desenvolvimento dos frutos. Termos para indexação: Musa
