Which citrumelo is better? More resistant, better flavor or earlier to harvest.

Yes, I have lots of ideas for future crosses, and I think a Morton x Bishop cross could be very good. Here's a small list of some crosses I may attempt next season:
Calamondin x Citrandarin (942, 1279, Bishop)
Kumquat x Citrandarin
Kumquat x Tai Tri
Clem-yuz x Citrandarin (942, 1279, Bishop)
Yuzu x Poncirus
Yuzu + Trifoliate (Carolina Chimera)
Yuzu x Tai Tri
Ichang Papeda x Poncirus
Ichang Papeda x Tai Tri
Ichang Papeda x Citrandarin (942, 1279, Bishop)
Your crosses sound very interesting, I'm looking forward to seeing them in the future!

Very cool!

I just collected seed from a Thomasville x clementine cross, waiting for germination on them. I don't think they'll be any more hardy than a satsuma, but they're the only cross I made that didn't drop when it failed to rain for the entire month of June...

My own 1279 graft looks to have a delayed failure of some kind so the crosses I was planning with it are going to have to wait. The same thing happened to the Bishop citradarin I had, but none of my other grafts, so something weird is going on with those two. In the meantime I'll likely be able to try some of:

Meyer lemon x Ichang papeda
Meyer lemon x Dunstan
Meyer lemon x Poncirus+
Ichang papeda x Ichang lemon (if the latter blooms, which it might)
Clementine x Dunstan
Clementine x US-802 (looks like it might bloom this spring)
Clementine x Poncirus+
Marumi x Dunstan
Marumi x Ichang papeda
Marumi x US-802 (if it blooms)
Marumi x Thomasville

Not sure these are the exact crosses I'll make, depends on bloom times and such, but that's the general idea. Bloomsweet, Ten Degree Tangerine, Poorman Orange, US-1516, US-852, and Taiwanica are all in the works to make crosses with as well, but I don't think they'll bloom this spring. A few others are on the list but won't be happening any time soon. I might pick up a 1279 and a Bishop citandarin from you if/when you offer them for sale again.

I've considered getting Excaliber Red Lime, SugarBelle (not sure about patents on that one though), Kiyomi, Cara Cara (pollen could be an issue though...) Eremo x Shek, Kishu, Ujikitsu, and Mineola for breeding with, but I doubt I ever actually will. If my satsumas ever actually produce pollen I'll be sure to try and mix them in with something, but again, I don't know if that'll ever actually happen.

Those sound like very interesting crosses too. I actually was gifted scionwood from a mature Clementine x Thomasville but I know nothing about it or its fruit. One of my micro-grafts of this combo has mixed foliage types. Have you tried Marumi kumquat? Is it fairly zygotic? Mine hasn't set fruit yet but I'm very interested in it.

Oh, I'll be very curious to know how that one turns out for you, I'll have an idea of what mine might be like in a few years. I'm hoping at least some of mine inherit the precociousness of Thomasville. With Thomasville being mostly nucellar, but with one fully zygotic parent (I assume, given the kumquat side), my guess is that half of the clementine x Thomasville crosses will be zygotic. If I'm really, really lucky, some of those zygotic ones will also be fairly sweet.

The only Marumi I've tried were under ripe fruit set during a summer flush. Even then, they were nice, if sour and underdeveloped. I'm expecting it to be zygotic but I don't know for sure if it will be.

Most of these crosses aren't going to be sufficiently hardy even in my warmer zone. My expectation is on the F2 generation or on a backcross they'll start to have decent hardiness.

Till:
Batumi Citrumelo tastes good. It is not very bitter and has no Poncirus flavours. Hardiness is said to be not very good, however.

African Shadock x Poncirus bears fruits of Navel Orange size and the fruits grow fast. Ripens partly in late autumn and partly the next spring. It grows well. Unfortunatelly, the fruits taste awsome. Very bitter and with resinous smell. Seeds seem to be largely nucellar but sometimes you get a zygotic one.

Swingle 5 Star was never my favourite in taste. I had my own fruits and got some from Ilya. All very bitter. But a surprise came this year. A Swingle 5 Star mutation (outwardly just Swingle 5 Star) from Ilya bore fruits that were not very bitter and quite good. I had a Swingle 5 Star seedling which I believed to be nucellar bearing fruit at the same time. The taste was just like Ilya's mutation, i. e. quite good. Now I do not know what I should think. Has my taste changed or are the fruits better? The latter will be true since my  wife found the fruits also ok. Conclusion: Swingle 5 Star can be pretty good.

I have another Citrumelo labbeled with the strange name "Yuma Gwange x Poncirus Changsha Citrandarin". Obviously a mislabeling supposedly from handwritten "Yuma Citrange" and "Poncirus x Changsha Citrandarin" belonging to the next line in the catalogue. This citrumelo is similar to Swingle 5 Star, grows well and has fruits with a high percentage of zygotic seeds (sometimes over 50%). Fruits are very aromatic but with too many unfavourable tastes. It has set hybrids with Morton, Sucrena and other varieties. If it is indeed the so called "Yuma Citrange" you would have it in America. I would recomment it for breeding because of its moderate acidity and complex aroma. For fresh consumation it is not suitable.

Citrumelo 5* can be very good if you store it for a while after picking the fruits. I squeezed fresh fruits and they were not very juicy but from stored fruit you can get quite an amount of grapefruit-like juice wihout resin and poncirus bitterness. It resembles quite exact the juice of white grapefruit. Just dilute with water 1:1 and enjoy.
