Desempenho agronômico de clones de bananeiras tipo prata tolerantes à murcha de Fusarium

Abstract

The evaluation of new banana genotypes with agronomic potential and tolerant to the main pests and diseases is essential for the market. The objective was to evaluate the vegetative and productive characteristics of new potential banana clones Prata Gorutuba R1 and Prata Gorutuba R2 and commercial cultivars. The experiment was implemented in a rural property located in the municipality of Nova Porteirinha, MG. The treatments consisted of banana clones Prata Gorutuba R1 and Prata Gorutuba R2 (genotypes selected from the 'Prata-Anã' clone Gorutuba tolerant to Panama disease) and four cultivars: Prata Gorutuba, Prata-Anã, Grande Naine and BRS Princesa. The treatments were distributed in randomized blocks, with four replications and six useful plants per plot. The planting spacing used was 3.5 m x 1.7 m. The evaluations were carried out in the first and second production cycles. The Prata Gorutuba R1 and Prata Gorutuba R2 clones in general showed excellent performance compared to the already consolidated cultivars. The clones presented median height and number of leaves in the ideal flowering for banana trees of the 'Prata' subgroup. Bunch and bunch weight, as well as production were similar to the Prata-Anã, Prata Gorutuba and BRS Princesa cultivars. Considering that the clones evaluated present high tolerance to Fusarium wilt, the result indicates that the materials have great potential for the registration of new cultivars.
