Discussion

Cucurbita andreana Naudin, a wild species native to Argentina and Bolivia, hybridizes readily with C. maxima and is its ancestor (O. I. Sanjur et al. 2002); it sometimes is recognized as C. maxima subsp. andreana (Naudin) Filov.

Some fruits of Cucurbita maxima have a high sugar content and are used for making pies, and they are popular as a soup, especially in Brazil and Africa.

All of the giant pumpkins in weigh-off contests are derived from Cucurbita maxima, as are some of the Halloween pumpkins. In 1904, the largest pumpkin was 403 pounds, and winners increased relatively little to 459 pounds in 1980. A rapid increase in size began in 1981, with the champion at 493.5 pounds; from this individual’s lineage came seeds for the Atlantic Giant cultivar, which has contributed since to winners burgeoning in size. The first giant pumpkin over 1000 pounds (1061 pounds) was grown in 1996; by 2009 the winner was 1725 pounds and in 2010, 1810 pounds.
