Abstract

The purpose of this current study was to morphologically characterize 37 accessions of mango taken from the germplasm bank at RozarioIzapa experimental station of the National Forestry, Crops and Livestock Research Institute (CERI-INIFAP) in Mexico, in order to support genetic improvement programs for mango. We used 49 varietal descriptors for this species. Characters were analyzed through Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), and Cladistics Analysis (CA). Principal Component Analysis (PCA) indicated that the first eight components generated 61.4% of total variation. The other 32 characters permitted to make a distinction amongst accessions and so we formed three groups via HCA: group I using material from Guatemala Rey Jorge and Suchitoto, group II with regional criollo material from Mexico Ataulfo andmanililla; and group III using Floridian-type materials. Cladistics Analysis (CA) allowed the formation of eight groups and eight materials being grouped alone, the distinction from the three groups was mainly determined by embryos (monembryony and polyembryony) also by their geographical origin and high heritability characters such as fruit skin color at physiological maturity, fruit skin color at maturity and ripeness, shape of left shoulder, skin thickness; core and fruit core depth. We determined the existence of a wider genetic diversity in the studied accessions of mango so it can be used for the genetic improvement program.
