The UCR profile identifies CRC3804 as Whitney Marsh grapefruit (PI539480, VI148) and reports that budwood was received from Whitney Ranch, Oasis, California, in 1961. It gives no known parents and notes the accession traces to a high-yield tree with good-quality fruit. A 1988 note says it appears identical to Marsh and CRC3184 (Frost Marsh), so this separate accession record does not establish a distinct phenotype or pink flesh. UCR classifies it among white grapefruits; its reproduced 1967 description reports pale-yellow fruit and buff-colored flesh. Riverside season is listed as January–May; the profile says it is not commercially available and has no approved budsource.
