Eustis Limequat Budwood

x Citrofortunella sp.

Parents unknown. Duncan grapefruit is believed to be the oldest grapefruit variety grown in the United States.  Although not named until 1892, it was growing as early as 1830 near Safety Harbor, Florida.

The tree is large, spreading, and grows vigorously.  The fruit is almost round and has a smooth, light yellow rind.  The flesh is very pale yellow, juicy, and seedy.  The flavor is considered by many to be superior to similar seedless grapefruit varieties.  Duncan is considered to be somewhat early in maturity.  The fruit holds well on the tree.  As with other grapefruit varieties, it should be grown in locations that can satisfy its high heat requirement.

Fruit large, oblate to globose or broadly obovate; basal furrows short and radiating; areolar ring faint; seedy.  Color pale to light yellow.  Rind medium-thick and surface smooth and even.  Flesh color buff to chamois-colored; tender, very juicy; flavor pronounced and excellent.  Medium-early in maturity.

Tree vigorous, large, very productive, and reputed to be probably the most cold-resistant.

Rootstocks of accession: Carrizo citrange , C-35 citrange.

Season of ripeness in the Riverside climate and latitude: January to May.
