Summary from transcript: The grower reports flowering from about one year and fruit retention after two to three years in fast-flowering trifoliate material. An own-root plant is distinguished from one grafted onto standard trifoliate. Repeated blooms are suggested as a source of fresh pollen; fruit is harvested before predicted freezing. No measured cold exposure or fruit chemistry is reported.

Archived grower discussion of fast-flowering trifoliate material supplied by Ned to Laaz and subsequent seedlings. Reports include early flowering, small or slow growth and differing seedling outcomes. The thread does not establish one verified clone or identity with the Chinese research mutant. Relevant posts are identified by author, displayed date/time and ordinal because individual post links are not exposed.

In page 2, post 3 (September 5, 2013, 2:24 pm), Sylvain answers affirmatively when asked whether the fast-flowering trifoliate material is polyembryonic. No method, seed batch, embryo counts or numerical rate is supplied, and identity with the Chinese research mutant is not established.

Research on Chinese early-flowering and wild-type trifoliate material. The Background reports discovery of the mutant in Yichang, Hubei, in 1976; Background and Results give differing juvenile-period figures. The study does not connect its experimental material to the forum or video plants, and expression differences do not prove a causal mutation.

Reply 848 (message 562932) directly answers a question about Precocious Poncirus hardiness. The author reports two plants, one own-root and one grafted onto standard trifoliate, emerging without damage from separate winters described as a “1f and 2f polar vortex.” Exposure duration, site and individual plant-level minima are not reported; the author’s prediction that it would tolerate lower temperatures is not an observation.
