Origin

The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone F-56-11): "Glen is a nucellar selection originating from Glen St. Mary’s Nursery. Found as a group of trees in a Washington navel grove of W. G. Roe of Winter Haven. It was named and introduced by the Glen St. Mary Nurseries of Glen St. Mary, Florida. The 56 clonal selections are seedlings of the Glen navel. The DPI released clones originated as seed from flowers pollinated in March 1955. The seed were planted at the University of Florida horticultural greenhouses in December 1955. The seedlings were received in Winter Haven from the Gainesville laboratory 9/4/1957 and assigned the SPB number 43. These seedlings were moved to the original DPI foundation planting north of Haines City. The original 56-11 & 56-12 trees were planted 3/7/1960 in row 56 of the foundation grove in tree spaces 11 & 12 respectively."
