There is scarce information available about how peasants recognize Agave landraces. This study aims to identify the agave species and landraces used for “pulque” production and analyze their morphological variability in a Nahua community, San Pedro Tlacuapan (SPT), Tlaxcala, Mexico. To this end, we used traditional knowledge and conventional statistical methods. Semi-structured interviews were administered; from these, the frequency of mentions, lexical marking, and perception about each landrace were evaluated. A total of 36 morphological vegetative characters were measured in the main landraces, and ordination analyses (PCA) were performed. SPT is home to 8 landraces of Agave americana and Agave salmiana subsp. salmiana. “Manso” was the most frequently mentioned landrace, and 5 qualitative characters used by local experts to identify landraces were observed. One morphological cluster was associated with each landrace analyzed, and the variables characterizing them are rosette size, leaf shape, number of leaves, and tooth shape. The information about agave diversity from local experts can be integrated into measurements of morphological diversity through conventional statistical methods.
