Persea schiedeana, a close relative of avocado (Persea americana), is an important part of agroforestry systems and diets in parts of Mesoamerica, particularly in the coffee growing areas of southeastern Mexico and Guatemala, where it is known as chinene, coyo, and yas. Little research attention has been given to this species, other than as a rootstock for avocado. Research carried out in six villages composing the Comité de Recursos Naturales de la Chinantla Alta (CORENCHI) in Oaxaca, Mexico shows that Persea schiedeana has potential as a supplement to avocado production in subsistence systems and as a potential oil crop in more market oriented agroforestry systems. This survey of Persea schiedeana in the Chinantla area reports on the ethnoecology and management of chinene, as well as on the morphological diversity of the fruit in the area. High morphological diversity for fruit characters was noted and it is suggested that artificial selection has occurred and been modestly successful for desired fruit characters. Superior fruiting trees, identified during village level “chinene fairs” were targeted for vegetative propagation as part of a participatory domestication project. Such superior genotypes hold potential for addressing food security and creating marketable products in tropical areas around the globe.
