Variação fenotípica em frutos de doze introduções de Cubiu (Solanum sessiliflorum Dunal) avaliadas em Manaus, AM, Brasil

Abstract

Phenotypic variation in fruits of 12 accessions of cubiu (Solanum sessiliflorum Dunal) evaluated in Manaus, Amazonas, Brazil. The cubiu was domesticated by the amerindians and has considerable economic potential for modern agro-industry. Fruit of 12 accessions werw evaluated to determine differecens among these in yield, fruit shape and dimensions, and several economically important characters ( pulp thickness, juice volume, Brix). There exists considerable variation in all characters evaluated, especially size and number of fruits. Brix varied from 4 to 6 and juice volume from 10 to 30ml, in fruits that varied from 40 to 190 g. There is sufficient variation in these 12 introductions to permit rapid genetic advance during breeding for any agro-industrial requirement.
