SEGURA LEDESMA, S. et al. Genetic resources of fruit trees in Michoacan. Rev. Chapingo Ser.Hortic [online]. 2009, vol.15, n.3, pp.297-305. ISSN 2007-4034.

This study is an inventory of the genetic resources of fruit-bearing tree species present in Michoacán and the state of their conservation and use. Studies on fruit-bearing species were reviewed exhaustively. The information collected was ordered by botanical family, genus, species, and collection. The 134 species found in Michoacán belong to 24 taxonomic families. In the management of genetic resources of this group of plants, ex situ conservation plays an important role: 38 species are conserved ex situ; of these, eight species are conserved in botanical gardens, three species are conserved in vitro, 23 are in field collections, and, only three species are in bank collections. A total of 271 accessions are conserved ex situ. Four species are subject to genetic breeding. Five species are conserved in situ in home gardens. Forty species are found in herbariums and there is a notable increase in the register of people consulting the information existing in the research institutions of the state.

Keywords : diversity; conservation; utilization; fruit-edible species; México.
