GENETIC RESOURCES OF AVOCADO (Persea Americana Mili.) AN RELATED SPECIES IN MEXICO

Abstract

In order to know the avocado genetic resources distribution in México, and their genetic diversity, collecting missions have been achieved in 24 States. The collecting sites and areas are described, and the gathered material - vegetative, fruits and seeds –is characterized according the UPOV Guide. We have a preliminary taxonomic dassification inside the genus Persea, and the major areas of genetic diversity are presented. Additionally, relationships between taxons and their environments have been established. Up to date, we have treated with about 600 accessions form Persea americana Mili. induding the three horticultural races, and Persea schiedeana Nees.
