Rootstocks of accession: Carrizo citrange, C-35 citrange

Notes and observations:
These plants were growing at the United States Plant Introduction Garden, Glenn Dale, MD; originally grown by the Office of Crop Physiology and Breeding Investigations (CPB), a section of the Division of Horticultural Crops and Diseases. Numbered in January 1935 for convenience and distribution. Upon brief observation, this accession was very dry and ricey textured, and did not match Groff's description.
Description from George Weidman Groff's "Culture and Varieties of Siamese Pummelos as Related to Introductions into other Countries" (December, 1927):
"Kao Pan (which means "white flat") fruits are subglose, flattened, pistil-end depressed, and are without a neck. The rind is light to lemon yellow, smooth, and 1-2 centimeters thick. They have 12-15 segments, separating with difficulty. Flesh is light yellow. Each juice vesicle can be separated. They have a sweet, very mildly acid flavor, and there is slight to no bitterness."
Description from The Citrus Industry Vol. 1 (1967):
" Fruit medium-large, subglobose to spherical; apex slightly depressed; seedy if open-pollinated, but otherwise not (Soost, 1964). Lemon-yellow (deeper than most) at maturity. Rind medium-thick; faintly pebbled with prominent oil glands; tightly adherent. Segments numerous (12-15); carpellary membranes thick and tough; axis medium-small and solid. Juice sacs large, fleshy, easily separable, and moderately juicy. Flavor sweet and mildly acid. Early in maturity.
Availability: Not commercially available in California.
