Abstract

Standardized criteria are needed to select seedlings of mango (Mangifera indica L.) that merit retention in a varietal improvement program, and to compare selections and cultivars evaluated. Such a slate lets seedlings and new or uncommon cultivars be compared with well-known standards. Preferences may vary in different regions, and performance of a given cultivar may vary; however, application of this system or clearly defined modifications of it can enhance the interchange of information and plant material worldwide among people working to improve mangos. Traits of importance arc shape, size, colour, firmness, fiber content, disease resistance, flavor, and productivity. A tabular system for rating these characters like those already used for strawberry and blueberry was developed and is being used to advantage in a program of mango germplasm evaluation. Occasional defects such as fruit cracking, "jelly seed" or stem end breakdown are noted when necessary in a "Remarks" column. A "Score" column permits one or more checks to give an estimate of overall quality, and a tree slated for discard is also designated here by a special sign, "[x]". ----- Seprecisan criterios para seleccionar plantas de mango (Mangifera indica L.) de semillero que merecen retenciJ'n en programas de mejoramiento, y para comparar selecciones y variedades ya evaluados, Tal sistema per mite la comparacid" n de plantas de semillero y nuevas variedades con variedades establecidas. Preferencias pueden variar de regidn a regid'n, y el cornportamiento de una variedad puede variar; sin embargo, la aplicacidn, de este sistema 0 una clara modificacid'n de ello podrfa aumentar el intercambio de inqormacion y materia vegetal entre todos que trabajan para el mejoramiento del mango. las caracteristicas mas importantes de la fruta son la forma, tarnailo, color, firmeza, cantidad de fibra, resistencia a enfermedades, sabor, y productividad. Un sistema tabular para evaluar estas caracteristicas fue desarrollado y utilizado con ventaja en un programa de evaluacion de germoplasma del mango. Defeetos de la fruta, tale como rajadura, pUdricion interna, y pudricion por el tallo se notan en una columna para comentarios cuando sea ncccsario, Otra columna permite marcar una o mas veces para indicar la caIidad general, y la marca "[x]" se usa para indicar la elimmacidn de una variedad o seleccion.
