Where Do We Go with Annona in Mexico?

Genetic resources information about seven Annonaceae species from Mexico were revised and linked to geography of the country. The collects of A. cherimolia, A. muricata, A. squamosa, A. reticulata, A. glabra, A. globiflora, and A. diversifolia are presented as species maps which represented regions where the climate is similar to that in sites where samples were collected. Some species showed evidence of intra-specific variation in their climatic adaptation. The eco-climatic diversity by means of cartographic representations permitted us to identify climatic particularities of these species. Complementary information about genetical resources of each species was revised focusing on studies in Mexico. Different species require different strategies to conserve and use their genetical resources. This study demonstrates how potential distribution and climatic suitability maps for Annona can complement genetic information in a way that delineates intelligent strategies for genetical resources studies by species. The research on Annona diversity in Mexico has been restructured by the Mexican Annonaceae Network ( REMA) of the National System of Genetical Plant Resources and these results are expected to be a useful tool for planning collections, both ex situ and in situ conservation, breeding, and use of this group of fruit plants in the country.
