TRIUMPHTRIUMPH

Photos by Toni Siebert and David Karp, CVC, 5/22/2008. Photo rights. C-35 left, Carrizo right, 23 year old trees. 

 

Source: Received as budwood from Dr. Fawcett's #124, Florida collection, 1914.

 

Parentage/origins: This was the first named grapefruit variety, having been offered to the public in 1884.  The parent tree, presumably a seedling, was situated in the grounds about the Orange Grove Hotel in Tampa, Florida.

 

Rootstocks of accession: Carrizo citrange, C-35 citrange

 

Season of ripeness at Riverside: February to June

 

Notes and observations:

1985, EMN: Hybrid-orange taste? This accession had exocortis, removed by shoot tip grafting. The Citrus Industry description suggests that this might be a natural orangelo instead of pure grapefruit.

5/29/2009, DK & TS: Small, round fruit; seedy; flesh greenish yellow, flavor sweeter and more orangey than grapefruit; light citrange aftertaste, not pleasant.

 

Description from The Citrus Industry Vol. 1 (1967):

" Fruit medium-small, oblate, globose, or ellipsoid; somewhat flattened at both ends; very seedy.  Color pale to light yellow.  Rind medium-thick with very smooth surface. Tender and very juicy; flavor lacking in bitterness and exceptionally good.  Early to midseason.
      Tree less vigorous than most grapefruits but productive.
      This was the first named grapefruit variety, having been offered to the public in 1884.  The parent tree, presumably a seedling, was situated in the grounds about the Orange Grove Hotel in Tampa, Florida.
      Being the first named variety, it was early and widely distributed though it did not achieve much commercial importance and has been little planted for many years.
      Its lack of bitterness and rich flavor are suggestive of the orange and some have thought that it might be a natural orangelo (orange-grapefruit hybrid).  In lack of bitterness it rather closely resembles Imperial of California origin and is somewhat like Mott (Aurantium), Leonardy, and Royal, all of Florida origin, though the latter is even more orange-like.  Indeed, these varieties appear to constitute a natural group of grapefruits in which the distinctive bitterness is lacking or they may be of hybrid origin.  With the exception of Triumph, currently employed primarily for home planting, none of them has attained commercial importance.
      The Jackson variety of South Africa is said to be a seedless budsport of Triumph."


Availability: Not commercially available in California.
