First-hand report from raregrowsnj in New Jersey. The author corrected the tree identification to Bishop Citrandarin. The original forum thread is titled “US-852 seedlings in Greenville NC”; its title does not describe this grower’s location. Paraphrased account, not an independently verified trial.

Summary from transcript: The Mulberries compares Bishop and US-1279 in central North Carolina. Bishop is described as an Alan Bishop selection from US-852, with some white double flowers, mixed leaf forms, and upright or shrubby growth. Recently transplanted Bishop trees showed more sparse foliage under heat and drought than US-1279. Both had generally good winter performance at this site. The presenter recalls Bishop fruit as sweeter and less herbal than US-852 and discusses seedling selection and breeding potential.

Summary from transcript: The Mulberries tastes Bishop alongside US-1279 and US-852 using fruit supplied by Mel in Pennsylvania. The Bishop sample weighs 58 g and reads 10.5 °Brix; a color-based pH test is estimated at 3 or below. Bishop has moderate seeds and juice, somewhat difficult peeling, and bitter low-to-medium-quality zest. Its moderately sweet, tart orange-and-lemon flavor is less herbal than US-852, with very slight bitterness and low perceived trifoliate influence. The presenter enjoys it fresh and suggests juice and marmalade, while US-1279 has a distinct mango-like flavor.

Summary from transcript: Virginia Fruit Grower compares Bishop Citrandarin, Dimicelli, and Prague Chimera. Bishop was originally sold as US-852 but was distinguished by its fruit and double flowers. The Bishop sample is about 5 cm across and reads 14 °Brix, with orange-colored flesh, numerous seeds, an orange aroma with only a very mild trifoliate note, and a tart orange flavor. The presenter would eat it fresh or use it for juice. The later Dimicelli and Prague readings and cold-tolerance discussion concern those varieties separately.

Companion scorecard to the Bishop fruit review, not an independent sample. It records ≤3.0 pH and 58 g. Its 12 °Brix entry differs from the video transcript’s 10.5 °Brix; the existing video reading is retained and the scorecard is not added as another measurement.

Summary from transcript: Bishop Citrandarin was sweet enough to eat out of hand with fewer off-flavors than US-852 in the speaker's personal comparison (16:50–17:54).

Individual scorecard image for Bishop Citrandarin. The printed preference ratings are sweetness 8/10, sourness 5/10 and bitterness 8.5/10; 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.

Original grower post #4. Kumin reports that Bishop defoliated but survived at 2°F during prior winters. No exact tree age, event date, duration, protection details, or measurement method is stated; this anecdotal report does not establish a hardiness minimum.

First-hand grower report that Bishop showed no visible damage in a tunnel. The same post gives an 8°F figure for foliar damage to a separate 5-Star Citrumelo plant; the temperature and exposure are not assigned to Bishop.

Post #488666 is a quick visual inspection of selections that stayed outdoors over the winter; the author reports Bishop Citrandarin was heavily damaged but likely to survive after a sustained low of “2 degrees” during high winds. The unit and exposure duration are not stated in this post.

The author reports variation in cold resistance among Bishop seedlings. This is a progeny-population observation, not a fixed hardiness rating for the Bishop clone.

Post #572336 reports one Bishop fruit picked December 2 at 12 °Brix, then says a fruit picked a couple of weeks later was about the same. The post does not say the second fruit was also exactly 12 °Brix; do not calculate a mean or treat the two descriptions as a standardized sample.

Post #572315 compares Bishop, US-1279, and US-1282 fruit, described as somewhat immature and affected by excessive shade. It calls Bishop the largest and prefers it for size and possible earlier ripening; it estimates roughly 50% zygotic seedlings. These are grower observations and an unverified seedling-origin assessment, not a genetic test. Relative flavor preference is not an intensity score.

Post #572329 compares Bishop with US-1279 and reports the grower’s seedling-vigor assessment. Bishop’s nucellar seedlings are described as vigorous, while many seedlings the author considers zygotic show lower vigor; the author says this may depend on the pollen parent. No method or genetic test is reported. The US-1279 seedling classification and vigor comparison remain grower assessments.

Kumin says Bishop’s parents bloom on new growth and that this appears to delay fall fruit maturity. This is the grower’s interpretation, not a controlled flowering-time trial.

Kumin reports Bishop fruit developing and attributes delayed autumn maturity to blooming on new growth. He contrasts it with Conestoga 004, which blooms on overwintering flower buds and was at least a month ahead in ripening in his comparison. This is a source-specific grower comparison.

Kumin reports severe damage among Bishop seedlings, with some possibly resprouting from roots, in the winter event that reached −8°F. He notes 4–6 inches of snow cover during the lowest temperatures. The account concerns seedlings and does not establish clone hardiness.

Kumin reports Bishop fruit at 12 °Brix and describes the fruit and juice as highly colored. He says he is a collector, breeder, and propagator, not the originator of the tree. The post does not specify sample count or measurement method.

Kumin reports Bishop seedling survivors after the same −8 °F event described in post #550214. He says they were protected by snow during the coldest period while the soil remained frozen for a month, and attributes seedling variation to winter weed cover. These posts concern one event, not independent exposures or a reported sample count.

Kumin corrects his earlier description of larger Bishop seedlings as zygotic, saying they were predominantly nucellar. This is the grower's reported classification and correction, not a genetic test; it concerns the previously discussed seedlings, not every Bishop seedling.
