Abstract

At the present time the society has a better concern for the conservation of the genetic diversity, beca use the gene tic diversity of each country is the most essential tool for the breeding program, of this manner must put special attention to establishment the plots or germplasm banks. At the Fundación Salvador Sánchez Colin, since 1989, with the support of the different national and intemational institutions we have carried out activities of exploring, collection, preservation and evaluation of different materials of Persea genus. Today the natural patrimony of the preserved genetic diversity is of 185 collections among the Persea and Beilschmiedia genus. Of the Persea genus in addition to the three races and of the local selections grouped as hybrids are counted on the following species: Persea steyermarkii, Persea schiedeana, Persea nubigena, Persea lingue, Persea indica, Persea fIoccosa, Persea cinnerascens, Persea gigantea and the other dassified like Persea spp. Conceming related species has to Bei/schmiedia with the following species: Bei/schmiedia anay, Bei/schmiedia miersii.
