Fully ripe fruit, easily detached, good outside satsuma smell, rich orange color,
13°Brix, concentrated juice, very pleasant satsuma like taste

Thank Ilya you for your interesting report.
The picture of the entire plant is interesting because it shows the variety of growth forms and thorn development. Taken together, these are all characteristics that my several, even smaller plants also exhibit, sometimes only individually.
As for the fruit, it seems to be mostly a pure mandarin, so few Poncirus cells are recognizable in the chimera... However, the thickening of the peel indicates a disorder, possibly PT cells. Have you tasted the peel, especially at this thicker spot?
What were the coldest temperatures your plant has already withstood?

Thank you,
Indeed, everything is twisted in this variety, so no wonder the peel is not uniform.
I was always intrigued by the absence of trifoliate taste in its fruit reports.
The smell actually is of pure satsuma and neither albedo nor flavedo do not have any special notes, the bitterness is on the level of satsuma peel.
The same can be said on the taste of central white region that is a part of vascular system, supposed to contain only poncirus cells.
I have had Prague since 2002, bought a very small plant grafted on PT from B.Voss. It was in open since 2003, never protected , experienced many episodes with frozen grounds, the lowest temperature was -16C in 2012, when it lost the tips on a new summer growth.
It was flowering but no fruits and stayed very small.
I never observed any pure poncirus or satsuma stems on it.
In 2016 I regrafted it on 1 m high poncirus stem, grown from the seeds sown in situ. Last year it brought the first fruits, that were ridiculously small. So, this year it has been its first harvest. The lowest temperature since 2016 was -11.5C.
