Duncan (mango)
Encyclopedia
The Duncan mango is a named mango cultivar that originated in south Florida and was later patented.
. Sturrock had written in 1969 that it had been a cross of Edward
and Pico, but a 2005 pedigree analysis indicated that Nam Doc Mai was the likely parent. This explanation is challenging because Nam Doc Mai was not introduced into Florida until the 1970s, and that Duncan is monoembryonic while Nam Doc Mai is polyembryonic. The tree first fruited in 1960 and the new variety was named after Ralph V. Duncan of Boynton Beach, Florida
, who was a flood control district supervisor that had provided maps for a book written by Sturrock. 'Duncan' was later was patented by Sturrock. The variety was recognized for its excellent eating quality and handling characteristics, as well as its production, and later became a nursery stock tree in Florida.
'Duncan' trees are planted in the collections of the USDA's germplasm repository in Miami, Florida
, the University of Florida's Tropical Research and Education Center in Homestead, Florida
, and the Miami-Dade Fruit and Spice Park
, also in Homestead.
The tree is a vigorous grower with a dense canopy. Both it and its fruit have very good disease resistance qualities.
