Cucurbita maxima morph-agronomic characterization genetic diversity genetic resources. In the Andean valleys of Argentina, families grow vegetables by traditional methods, mainly for self-consumption. Squash (Cucurbita maxima) is an American crop of great importance in Andean regional economies. These squash landraces are being lost by the rural exodus, the replacement of local varieties with commercial seeds and frequent droughts. They are reservoirs of genes of interest for improving the species and for ensuring local food security; their conservation and characterization are thus fundamental to avoiding genetic erosion. During 2005, sixty-one populations were collected from Valle Fértil, San Juan Province, and from the Argentinian northwest. Twentyseven were selected and tested for two years in the EEA INTA La Consulta, Mendoza. Forty-nine characters of plant, flower, fruit and seed were measured under a completely randomized design with three repetitions per population. Commercial cultivars Marino FCA and Veronés INTA were used as controls. The populations were grouped by fruit, seed and growth habit characters; a great morphological diversity was observed among and within populations. The work allowed selection of materials with desirable traits for improving the species. En los valles andinos de la Argentina las familias producen hortalizas en forma tradicional principalmente para el autoconsumo. El zapallo (Cucurbita maxima) es un cultivo americano de gran importancia en las economías regionales andinas. Estas poblaciones criollas de zapallos se están perdiendo por el éxodo rural, la sustitución de semilla criolla por semilla comercial y las sequías frecuentes. Constituyen reservorios de genes de interés para el mejoramiento y para garantizar la seguridad alimentaria local, por lo que su conservación y caracterización son fundamentales para evitar la erosión genética. Durante 2005 se realizaron colectas en Valle Fértil, provincia de San Juan y en el noroeste argentino; se colectaron 61 poblaciones, de las cuales 27 se seleccionaron y evaluaron durante dos años en la EEA La Consulta INTA, Mendoza. Se midieron 49 caracteres de planta, flor, fruto y semilla, bajo un diseño experimental completamente aleatorizado y tres repeticiones por población. Los cultivares comerciales Marino FCA y Veronés INTA se emplearon como testigos. Las poblaciones se agruparon por caracteres de fruto, hábito de crecimiento y semilla, observándose gran diversidad morfológica entre y dentro de cada población. El trabajo permitió seleccionar materiales con caracteres de interés para el mejoramiento de la especie.
