ResumoTwo botanical forms of F. chiloensis ssp.chiloensis have been recognized in Chile (Staudt, 1962): f. patagonica (referred to as Lahueñe in Chile), for the wild taxon with red small fruit common in Chile and Argentina, and f. chiloensis (previously referred to as Quelghen or Kellen in Chile), for the cultivated taxon of white and large fruit size, which is found in Chile, Peru, Ecuador and Colombia, probably carried from Chile by the Spanish conquerors (Hancock et al., 1999).The latter was domesticated by ancient inhabitants of Chile before the arrival of Spanish conquerors, and is still cultivated in small plantings [e.g. at Buchupureo (lat.36°S), Cañete (lat.37º30'S), Puerto Saavedra (lat.38º46'S), Carahue (lat.38º43'S)] along the coast of central-south Chile, in Mediterranean type climates.F. chiloensis f. patagonica is distributed in a wide range of climatic and ecological conditions, along the coastal lands and the Andes mountains, between lat.35°30'S and 47°33'S and between sea level and 1850 m elevation (Lavín et al., 2000).It is found in Mediterranean, marine and polar type climates, and in various soil types and plant communities.F. chiloensis f. chiloensis is generally found near water between see level and 500 m (Lavín et al., 2000). Materials and MethodsA morphometric analysis of 66 Chilean accessions of Fragraria chiloensis (L.) Duch.was performed to asses phenotypical differences among them.Accessions were collected in expeditions in 1993 between 41° and 47°S.Plants were planted in plastic bags and placed in rised beds outdoors.A selection of eleven vegetative, four infl orescence and fi ve fruit
