yield is estimated between 4000 and 5000 kg/ha (Gepts, 1993). Low yields can be attributed in part to the poor The diversity, structure, genetic flow, and evolutive relationships knowledge and limited use of the genetic diversity of within and among three wild–weedy–domesticated complexes and a wild populations of this species (Gepts and Debouck, wild(More)
Traditional farming communities frequently maintain high levels of agrobiodiversity, so understanding their agricultural practices is a priority for biodiversity conservation. The cultural origin of agave spirits (mezcals) from west-central Mexico is in the southern part of the state of Jalisco where traditional farmers cultivate more than 20 landraces of(More)
The genetic diversity ofP. lunatus in the Yucatan Peninsula was assessed on the basis of its morphological and phenological characters. Our results were then discussed in relation to ethnobotanic information obtained about the intraspecific diversity recognized by farmers, their selection criteria, agronomic management, production purpose and percentage of(More)
The role of gene flow in autogamous domesticated species diversity and their wild relatives is an issue that requires more field data. Using nine microsatellite loci, an analysis was done of the magnitude and direction of gene flow in the wild–weedy–domesticated complex of Phaseolus lunatus L. under traditional agricultural conditions in four regions on the(More)
The pattern of morphological variation of Cocos nucifera in Mexico was statistically and numerically evaluated. Forty-one populations were analyzed, using 17 morphological fruit characters. Principal components and cluster analyses indicated four main groups of coconut populations that showed high similarity with four different genotypes recently imported(More)
Recent paleoecological, archaeobotanical and genetic-molecular data are used to develop a hypothesis on the where, when, how and whom of plant domestication and the origin of agriculture in west Mesoamerica, and the formation of the maize-bean-squash multicrop milpa system and agro-food system which formed the base for development of ancient complex(More)
The Lowland Mayan culture has been one of the most successful in Mesoamerica. Being an agricultural society, part of their success was based on plant genetic resources which satisfied their needs of social reproduction. This article reviews recent evidence on early agriculture in the geographic area where Lowland Maya culture originated, and discusses its(More)
Lima bean (Phaseolus lunatus L.) is an important crop in traditional Mayan agriculture of the Yucatan Peninsula, Mexico, its Mesoamerican center of diversity. Genetic erosion in this species is currently a threat in this region out of 3 of 21 landraces dominate 71.24% of the cultivated area, and 12 are rare landraces grown only in 6.29%. Using 90 ISSR loci,(More)
Extensive monovarietal cultivation of Age tequilana Weber var. azul is threatening the diversity of the germplasm used in traditional Agave spirits production in west-central Mexico. To promote the preservation, use, and management of this germplasm, an ethnobotanical and morphological study was done in the center and south of the state of Jalisco, Mexico.(More)
The genetic diversity of coconut palm in Mexico has arisen from introductions carried out during the Spanish colonial period (1539–1810). The interest of estimating the extent and origin of the genetic diversity motivated the investigation of sites, dates and origins of the introductions, the initial areas of production, the economic importance of the(More)
