Citrus paradisi Macfadyen
Photos by Toni Siebert and David Karp, CVC, 5/22/2008. Photo rights. C-35 left, Carrizo right, 25 year old trees.
Source: Received as budwood from New Zealand, 1943.
Parentage/origins: This variety originated as a chance seedling at Wheeny Creek near Kurrajong, New South Wales, Australia, and was named by R. J. Benton, government citrus specialist.
Rootstocks of accession: Carrizo citrange, C-35 citrange
Season of ripeness at Riverside: January to May
Notes and observations:
WPB: Introductory tree pulled from nursery- new trees budded on Troyer citrange. Fruit has excellent flavor, no bitter taste. Seed is monoembryonic. While the fruit is grapefruit-like in most respects, the monembryonic nature of its seeds and some of the other characters suggest that it is probably a pummelo hybrid.
RRK: Excellent flavor, no bitter taste. Trees breaking from enormous crop load, but fruit still relatively good size; very seedy, has large hollow core, flesh lighter in color than other seedy white grapefruit.
6/10/2009, DK & TS: Very sour.
Description from The Citrus Industry Vol. 1 (1967):
" Fruit large, oblate or very broadly obovate to globose; both ends depressed, with small radially-furrowed basal cavity and broad, shallow apical basin; moderately seedy but monoembryonic. Color pale to light yellow. Rind medium-thin with moderately rugose surface (not smooth as are most grapefruits). Flesh straw-colored; coarse textured but very juicy; flavor good but acid (virtually indistinguishable from some grapefruits). Medium-early in maturity (as compared to the true grapefruits).
Availability: Not commercially available in California.
