Evaluating Important Fruit Characters in Mango Germplasm

Abstract

Standardized criteria are needed to select mango ( Mangifera indicaL.) seedlings that merit retention in a varietal improvement program, and to compare selections and cultivars evaluated. Such criteria allow comparisons of seedlings and new or uncommon cultivars with well-known standards. Preferences vary in different regions of the world, 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. Traits of importance are shape, size, color, firmness, fiber content, disease resistance, flavor, and productivity. A tabular system for rating these characters was developed and is being used to advantage is a program of mango germplasm evaluation. Occasional defects such as fruit cracking, “jelly-seed,” or internal breakdown are noted when necessary in a “Remarks” column. A “Score” column provides space to give an estimate of overall quality; also, a tree slated for discard is designated here by a special sign, “/x/.”
