Genome resource reviewed against the CGD assembly record and existing variety identity. ZK8 is a sequenced trifoliate-orange reference relevant to the Poncirus background inherited through C-35. It is not a sequence of Conestoga 067 Citrange or its recorded parental accession, and does not establish ancestry percentages or cold tolerance.

Forum grower report that Conestoga 067 had not flowered as of the post. This is a time- and site-specific observation, not a cultivar-wide flowering conclusion.

Post #488666 is a quick visual inspection of selections that stayed outdoors over the winter; the author reports Conestoga 067 survived with injury after a sustained low of “2 degrees” during high winds. The unit and exposure duration are not stated in this post.

The author reports that Conestoga 067 survived 2 °F with high winds “last December.” This is reported as a follow-up/clarification of the earlier outdoor winter account, not a second independent freeze event. The post separately compares Conestoga 058 as less hardy; that comparison does not assign 058 the 2 °F exposure.

The author reports that Conestoga 067 had recurring dieback and survived by virtue of being grafted onto Poncirus rootstock. This is the author’s interpretation of the observed plants, not a controlled comparison.

The author compares Conestoga 067's hardiness with Bishop and reports mixed leaf forms, including monofoliate leaves. The post provides no exposure measurement or genetic confirmation of its leaf types.

Wahl reports that Conestoga 067 made it through a 6°F low that year and contrasts Conestoga 058 as not doing so. The post gives no exposure duration or measurement method. A reply shortly afterward says neither 067 nor 058 survived outdoors; preserve these as differing grower reports rather than a reconstructed hardiness threshold.

Kumin reports that Conestoga 067 did not survive outdoors in his garden. This is a separate grower and garden from Wahl's #775 report that 067 made it through a 6°F low. Kumin does not give a temperature for 067 in this post; these reports are not reconciled.

Kumin reports beginning with an initial population of 20,000+ seedlings, estimating 85% nucellar and 15% zygotic, with an effective trial population of about 3,000. He says seeds germinated in April 2018 and seedlings were planted outdoors in June 2018 without winter protection. This post documents the trial setup and timing; it does not identify individual Conestoga selection 067 or establish its individual selection date.

Kumin says the seeds were planted April 12, 2018, germinated in a heated bed, then field-transplanted in early June 2018. He describes the trial population, not an individual Conestoga 067 tree; this post does not establish when selection 067 was named or its individual first-winter survival.

Kumin says the seed parent was an F1 C-35 citrange and that the pollen parent was not definitively known; he mentions a citrumelo or a different citrange as possibilities. This describes the trial seed lot, not a verified pollen parent or a selection-specific genetic test.

Kumin reports that Conestoga 067 showed some leaf-color change and minor deciduousness. This is a single grower observation; the post does not quantify leaf loss or establish a seasonal pattern.

Kumin identifies the plant in front as Conestoga 067 in a photo taken before survivor numbers were assigned. He describes the plants as original survivors and says Conestoga 058 is likely one of two monofoliate specimens; the post does not explicitly identify 067 as monofoliate or give a date or temperature for an individual survival event.
