This page states that the Umatilla flower used as Raspberry Tangor’s seed parent was a Satsuma × Ruby Orange cross. It does not identify which Satsuma or Ruby Orange selection. Umatilla’s current parentage record identifies ordinary Owari Satsuma × Ruby Blood Orange, reflecting Hodgson (1967), while the primary Circular uses generic Satsuma wording; this Panzarella account does not identify those selections. The page has no byline or publication date.

Citrus ID Edition 2, October 2011; no byline or publication day is shown. The structured description says the fruit is broader than long, the rind color ranges from yellow to orange, and the flesh is orange. A separate historical description attributed to Hodgson (1967) says the fruit is medium-large, reddish-orange and broadly oblate, tender and very juicy, rich but acid, and medium-late; the tree is described as slow-growing and spreading. The Origin entry attributes a Florida Satsuma × Ruby orange cross to 1911 and naming/description by Swingle, Robinson and Savage (1931). This combines an identification entry with an attributed historical account, not a current accession trial. No named accession, harvest sample date, rootstock, field protocol or taste method is given; Winter Haven photo captions do not establish the tree age or match the pictured fruit to the text.

Canonical primary publisher DOI record for this paper; ResearchGate publication 226864057 is the supplied discovery link. Springer gives July 2002 (the ResearchGate page displays June 2002). The available evidence is the publisher abstract; full text was unavailable. The abstract reports colchicine-induced regeneration of three non-chimeric autotetraploid plants from monoembryonic Umatilla callus at 0.05% and one at 0.1%, with no plants regenerated from oryzalin treatments; ploidy was assessed by flow cytometry and chromosome squashes. This is experimental in-vitro induced-ploidy work, not ordinary cultivar fruit, taste, field performance, release history or sexual-parentage evidence.

The archived message is a 1993 directory of mandarins, tangerines and hybrids, with no citation alongside the Umatilla entry. It lists Umatilla as a tangor (Owari Satsuma × Ruby orange), late season, large and red-orange, says its size and shape are like King, and attributes breeding to W. T. Swingle in 1911 and release in 1931; it also says “good quality.” The FAQ preamble defines season as ripening time and notes that it varies by climate. This is a secondary directory listing, not a cited trial or first-hand account; it supplies no Umatilla sample, site, rootstock, harvest date, taste method or flesh color. “Good quality” does not establish taste intensity.
