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 058 Citrange or its recorded parental accession, and does not establish ancestry percentages or cold tolerance.

Post #387020 reports aphid and slug attention to Conestoga 058, leaf-feeding damage on one small graftling, and a more pleasant leaf scent on the described plant. The author speculates about whether leaf scent may indicate fruit flavor; this post does not report a fruit tasting.

Post #386830 compares the original Conestoga 058 plant in a coldframe with Conestoga 010 and 011 grafted outdoors on Poncirus after an unspecified winter. It gives no winter temperature or duration; the differing protection settings preclude treating this as a common-condition comparison.

In post #488666, the author says Conestoga 058 was damaged at “15 degrees” in a tunnel and characterizes its hardiness as not exceptional. The unit is not stated for this figure; the post gives no exposure duration. Do not treat it as the separate outdoor comparison.

In post #414513, kumin describes Conestoga 058 as in poor condition, strongly evergreen, the most citrus-like, and the least cold hardy among the hybrids. The update gives a +10 °F low to date across the group; it does not identify that low as a Conestoga 058 exposure.

The post caption identifies Conestoga 058 as a monofoliate Segentrange sibling and describes its spines as very slender and rather long. The plants were shown before planting; the author’s planned slight protection from mid-December to mid-March is not evidence that this 058 plant received it or survived a particular winter.

The author captions the original Conestoga 058 tree as nearing three years old and describes it as the most citrus-like and least hardy of the seedlings, with the longest spines among the author’s trees, slender rather than stout like Poncirus. A separate caption identifies a grafted 058 plant on Poncirus at 16 months post-grafting; keep that plant distinct from the original tree.

The author describes the original Conestoga 058 selection as vigorous, with good graft takes, remaining dormant later in spring and growing late into autumn. Bruised leaves were fragrant. A graft of this tree survived outdoors the prior winter with considerable cold damage. Anticipated fruit tasting is not a result.

The author says Conestoga 058 is evergreen, quite vigorous, and the most citrus-like and least hardy of the two selections discussed in this sentence; it lacks Poncirus-like winter bud scales. The author predicts it may flower during the initial spring flush, which is not a reported flowering observation.

The author describes Conestoga 058 as a vigorous four-year-old tree that had not fruited yet, and captions its upper branches as largely monofoliate. The post separately shows a four-year-old A-026 fruit; do not assign that fruit to Conestoga 058.

The post states that Conestoga 058 has mostly monofoliate leaves and is less hardy than 067. The separate statement that 067 survived 2 °F with high winds last December belongs to 067 and is not a 058 temperature result.

The author says the seeds were planted April 12, 2018, germinated in a heated bed and field-transplanted in early June 2018; the seedlings were 9–10 months old at the winter low. This is a cohort-level setup report, not a report of the specific winter exposure or embryo origin of Conestoga 058.

The author says the seed parent was F1 C-35 citrange, while the pollen parent had no definitive identification and could have been another citrange or citrumelo. The statement concerns the seed lot/population; it does not establish the embryo origin of an individual selection.

The author identifies #058 as one of two monofoliate original survivors and says the photo was taken before survivor numbers were assigned. He says the pictured plant is likely the one in back, so the photo position is uncertain. The post supports later identification in the trial, not an exact selection date or numerical hardiness threshold.

The author says Conestoga 058 and 067 were largely monofoliate and had not fruited; he reports that 058 developed reddish-purple winter coloration and was a bit less hardy than Bishop citrandarin. The separate claim that 067 was a bit hardier than Bishop is not a temperature result for 058.

The author reports a branch of Conestoga 058 with red leaves during a leaf-color change and describes this clone as having the thinnest, longest spines among his trees. He says he does not know whether Ruby Blood Orange ancestry contributes to the coloration. This is one grower’s observation, not a measured color or genetic result.
