David Karp's article focuses on Seedless Kishu, not generic Kishu. It reports that budwood from Japan reached the UC Riverside Citrus Variety Collection in 1983; describes the fruit as smaller than a golf ball, easy to peel, tender, juicy, and fragrant; and reports grower Jim Churchill's 780-tree commercial planting and observation that older trees yield smaller fruit. Article-level regional and historical context; not a controlled trial.

Single post about the author's own Fairchild and Seedless Kishu trees on Flying Dragon rootstock. The author reports that they produced first fruit after three years in the ground and says he grew the rootstocks and grafted the scions. This joint report does not assign a cultivar-specific bearing age, exact planting or fruiting date, or accession.

hoosierquilt reply dated July 29, 2015, in the “Ponkan Tangerine” topic. The grower says, “For me, in my orchard, Seedless Kishu and Ponkan are tied for the top spot,” and describes Kishu's flavor as “the best flavor going.” This is subjective orchard preference and unscored flavor praise only; no exact orchard location, accession/tree, rootstock, harvest date, sample count, or tasting protocol is stated. Existing objective small-fruit, seedlessness, and peelability claims are already covered by other sources.
