Making improved citrangequat (Nagami x citrange Morton)

(1/2) > >>

Lauta_hibrid:
After so many attempts this year I got my first 2 hybrids of Kunquat Nagami x citrange Morton 💪🏻. If the hybrids we have are crosses with not so attractive citranges (in my opinion), what would happen if I made some with Morton? That was the question I had, to make an improved citrangequat... although only time will tell, it's a mystery so far. Many of the fruit were empty, but based on the growth they are having, it appears that the cross occurred. I already have other citrangequats made with Troyer (which has a very poncirus-like flavor), this would be the opposite. What do you think? Has anyone tried this?

Mulberry0126:
That is exciting news! I am looking to pollinate some of my kumquat flowers with US-852 pollen or vice-versa. Similarly, I think if a better hybrid is used we could attain a fruit similar or better to Thomasville. Extra cold hardiness would be a welcome benefit but I'm not sure how much will really be gained while still retaining good flavor.

In these graphs I made, we can see that genetic variability is very high. Who knows what might come out 😅. Statistics are king in this competition... they proved it by making Conestoga, F2 Citranges with more resistance than their father. I would try an F2 Citrangequat, maybe repeating genes from Kunquat and Citrange to achieve the same resistance but better flavor... and maybe the sweet skin 🤷🏻

tedburn:
I think every new crossing is interesting, the only problem with kumquat heritage could be the
late ripening time in zone7 and 8 with springfreezes which damage the fruit.

usirius:
The idea of ​​creating a new type of  Citrangequat sounds good. However, all the Citranges I know their fruits dont’t taste very pleasant, which means the result of crossing with them won't necessarily produce extrsordinary pleasant tasting fruits. I've switched to so only crosses with trifoliate hardy crossing partners whose fruits contains only a small amount of Poncirus taste like my HRS899 O/Q or other  improved Poncirus like trifoliate varieties which are also hardy to -20‘C and more.
