Exact post by kumin. The author reports that Major C. Collins of Tifton made the selection available to him about 40 years earlier; the purported flesh/juice-to-seed advantage and a lost former name remain source-reported. The author says he uses it as rootstock. This is not independently verified cultivar history, identity, or trial evidence.

Exact post by kumin. The forum displays “Today” rather than a calendar date on page access. The author reports Poncirus Plus ripening approximately 10 days later than Collins; the post gives no season, location, harvest criteria, accession verification, or sample size. This is an unmeasured, source-specific relative-ripening observation.

In reply #568619, kumin says Collins trifoliate had the most fruit pubescence among the selections discussed and was not part of the breeding program. The post gives no measured or quantified pubescence amount.

Kumin identifies this as the oldest Poncirus tree in the collection and says its origin was Major C. Collins in Tifton, Georgia. He reports fruit larger than average, slightly more juice and pulp, and no reduction in seediness. This is a grower’s strain-level provenance and relative fruit comparison; the post gives no accession verification, measurements, sample count, or test method.
