Summary from video review: Tough Citrus tastes seedy citrandarin fruit supplied by Stan McKenzie, finding mandarin-lemon flavor, sweetness, tartness, and a pungent oily trifoliate note. The presenter enjoys it fresh and discusses a general 0°F hardiness claim. No weight, Brix, or pH measurements are given. Captions were unavailable; this summary uses audio and visual analysis. The title identifies US-852, while the spoken review calls it citrandarin. Some of this older footage reappears in the later US-852 review.

Summary from transcript: The Mulberries compares US-852 with its Changsha parent using fruit from Stan’s farm. The US-852 sample weighs 101 g, reads about 11.5 °Brix, and gives a color-strip pH estimate around 3 or below. It is difficult to peel, very seedy, and less juicy than Changsha. The flavor is very sour lemon-mandarin with herbal notes, moderate trifoliate influence, little flesh bitterness, and no sticky resin. The presenter favors sweetened juice and marmalade, while describing fresh eating as a matter of taste. General single-digit and approximately 0°F hardiness reports are discussed without a documented freeze event.

Summary from transcript: One small US-852 tree flowers in midsummer after spring buds on several trees had fallen off. The grower attempts pollination with Fukushu kumquat pollen, hoping for a useful citrandarinquat. Ripened fruit and viable hybrid seeds are possibilities rather than confirmed outcomes.

Summary from transcript: Virginia Fruit Grower tastes several hardy citrus varieties, then reviews fruit supplied by a friend and labeled US-852. That fruit has orange skin, a thin rind, many seeds, orange aroma with a slight trifoliate note, and tart orange flavor suited to a sweetened diluted drink. Earlier measurements and flavors concern other varieties. The presenter’s later Bishop video explains that a plant sold as US-852 proved distinct; the identity of this older supplied fruit is not established as the same plant or as Bishop.

Summary from transcript: Tough Citrus revisits US-852, including older tasting footage and a later review of fruit picked with Stan McKenzie. The presenter describes sweet, very juicy, seedy fruit with a little bitterness, thin tough skin, and a Tang-like juice flavor. He enjoys it fresh and for juice, while noting irregular-looking tree growth. General Zone 7 and near-0°F survival claims are relayed without an event record. The repeated introductory tasting is not a second sample.

USDA authors describe the 1965 cross and August 1999 release for commercial rootstock trials in Florida. Performance findings concern grafted scions, not the eating quality of US-852 fruit.

Summary from transcript: In a Stan McKenzie shipment tasting, the presenter and spouse describe the title-listed US-852 fruit as a seeded, medium-juice, peculiar mandarin-like fruit; their equally diluted juice was sweet and tasty. Auto-generated captions retain cultivar-name uncertainty.

Individual scorecard image for US-852 Citrandarin. The printed preference ratings are sweetness 6.5/10, sourness 4/10 and bitterness 8/10; the linked fruit reference preserves these original ratings alongside catalog numeric scores. Sweetness is stored as printed; sourness and bitterness use 10 minus the printed score. Any Brix or pH printed on the card is a separate reading, not derived from ratings. Sample method and harvest date are not stated unless noted in the reference.

Peer-reviewed trial of Ray Ruby grapefruit scions on seven rootstocks in a commercial Indian River County, Florida orchard, with 2012–14 harvests. This record is cited only for the trial’s total-solids comparison for US-852 as a rootstock; it does not describe fruit borne by US-852 itself.

Pages 6–7 include Walt’s US-852 reports. In posts 131100 (Apr 7, 2019), 131120 (Apr 15, 2019), 131459 (Aug 23, 2019), and 131864 (Dec 6, 2019), he reports fruit sources, taste impressions, and seed counts. The claimed 60–70% zygotic share is an unverified estimate and is not treated as a measured rate. The Apr 15 post does not establish the tasted fruit’s source; the Aug and Dec posts concern separate batches.

Summary from transcript: At 1:50, the narrator says the US-852 tree experienced an “eight degree freeze” (unit not stated in the recovered captions), was unaffected, and later produced a good crop. Protection and exposure duration are unknown; this is one grower report and does not establish an absolute hardiness minimum. At 2:04–2:11 he recommends the fruit for juicing.

The trial evaluates Pera IAC sweet-orange scions on 13 rootstocks at Bebedouro, Brazil; its field outcomes and fruit measurements concern Pera IAC, not US-852 rootstock fruit.

Summary from transcript: At 6:44–6:57, Tough Citrus compares US-852 with US-942, describing US-852's rind as thin and nearly leathery relative to US-942's thick, plump rind. This is a retrospective comparison; no separate US-852 fruit sample or rind measurement is identified.

User-supplied page 3 HTML capture. Posts #122249 (May 22, 2017), #122250 and #122278 (May 22–23) discuss about three seedlings Walt initially labels “F2 or OP” and tentatively attributes to US-852 or US-832. imgrimmer identifies them as US-852; Walt confirms. The exchange does not resolve F2 versus open-pollinated origin. The post asserts a roughly 50% sexual-seedling proportion without a denominator or verification method; it is not treated as a measured rate.
