Thanks.   There are differences.  The leaves are unifoliate, there are no thorns and the fruit is larger.  Dunstan may taste better, and has a nicer color.  There are more fruit on the tree and hopefully they will ripen enough before cold weather for a more positive evaluation.

Is it F2 seedling of your own F1 PomeloXPT cross?

Yes, an F2 of the original cross.  The original crosses were made many years ago.  I moved and almost all of the plants were lost.  A few fruit were scavenged when I went back to my old place.  7 plants from one fruit have survived which appear to be zygotic.  Three have fruit now.

From research I've looked into in the past, there's probably a higher than 50 percent chance the seedling you grew was nucellar, so it may be an exact clone of the original parent hybrid. But there's also a fair chance, maybe somewhere between 20 to 40 percent, that the seedling could have been zygotic (probably resulting from hermaphroditic sexual reproduction. If that's the case there is a chance the genes might get scrambled around to improve characteristics of edibility and cold hardiness. But even those chances of an improvement are probably 1 out of 4, or 1 out of 8 (I would guess, from apply basic statistics to how dominant/recessive gene pairs work). I know this is very speculative but maybe that will give you some small idea of what could be happening here and the chances of any change from what you did here.

I do find it very interesting that you chose to use an actual pomelo in your (original) cross.

No, it is zygotic.  The parent had a smaller fruit.  The siblings have different characteristics
