Keith,
Its having been about a year since I last tasted a Mysore--and that having been my very first time tasting a Mysore--I can't make a fair comparison. From memory, though, I'd say that the fruit that Dan has labeled as Chini-Champa is fatter, more angulated, and not nearly as sweet. It doesn't have the acidic component that some people--myself included--find so alluring about Mysore. So I'm pretty sure it's a different fruit entirely. As to whether it is an AB, as a Chini-Champa is supposed to be, I'm not sure of that, either. Dan was very thorough in explaining how he came into the corm for this plant, but my account of the story would be just a butchered paraphrasing.
If I'm remembering correctly, Dan's CC is separated from his Pisang Ceylon by only one mat. Perhaps with a wide-angle it is possible with some winter pruning to get a set of pictures that encompass both plants and their p-stem and petiole characteristics. As long as he's happy with the fruit quality, though, I'm not sure that it matters what it is. (The fruit was much-appreciated here, whatever the case.
) But back-in-the-day, when legends walked the forum, the general consensus seemed to be that the only willing source out of India with a phyto certificate was
Ganesh Mani Pradhan & Son The Nursery . Who knows!
