Abstract

Introduction. Banana plants (Musa sp.) face problems caused by diseases such as Yellow Sigatoka (Mycosphaerella musicola), which is responsible for significant economic losses. Through micropropagation techniques, a somaclone variety called CIEN BTA-03 resistant to this disease was obtained. The purpose of this study was to compare fruits of somaclone CIEN BTA-03 and its parental clone Williams. Materials and methods. Fruits from both clones were studied, determining shape, weight, dimensions, proportions, pulp viscosity and consistency, total solids, soluble solids, pH, titratable acidity, sugars, ash, total phenolic content and crude fiber, and analyzing their color, odor and taste. Results and discussion. Clones differed in shape, weight and [pulp/peel] ratio. Pulps also differed in viscosity, pH, and soluble solids, sugars and phenolic compound contents. Differences between the two clones favored clone CIEN BTA-03, since it was better ranked for the color, odor and taste characteristics. Conclusion. Despite being resistant to Yellow Sigatoka, somaclone CIEN BTA-03 shows better sensory characteristics than its parental clone Williams.
