Cucurbita is a genus of about 27 species, and is indigenous to the Americas (Bailey, 1943; Castetter and Erwin, 1927). Most of the species are concentrated in Mexico and in the southwestern United States. Of the five cultivated species, all except Cucurbita maxima are found in Mexico and Central American. C. maxima was confined to Argentina, Bolivia, Chile, and Peru in pre-Columbian times (see Table 1).
