The Tropical Fruit Forum

There was a long discussion about the taste of Yuzu in Citrus Growers forum: https://citrusgrowersv2.proboards.com/thread/196/yuzu-taste. Most Europeans valued Yuzu very much while Americans were mostly not positively impressed. The reason seems to be that the Yuzu varieties in Europe are not the same as in the States.

I think there is much difference between old world culinary tradition as well as openness to new taste and preferences in the US. Yuzu-rind is not bitter at all 

Nice table! Data of Poncirus certainly depends on the cultivar. Poncirus can have 100% zygotic seeds or hardly 1%.

Never heard of 100% zygotic Poncirus

I think there are some members which have experiences with coldhardy citrus, but to receive answers you should ask more detailed what you are interested in. I e.g. I have a Yuzu since 3 winters in ground, froze to earth in winter after a low of - 15° C and has now recovered again or a Dunstan citrumelo seedlings two year old in ground took -13° C this winter - all survived, some with slight damages, others with none, depending on genetics and microclimate of place.

one thing I personally observed was, that C. ichangensis showed much more hardiness on its own roots than grafted on Poncirus. In direct comparison all grafted specimen died from cracks and all seedlings on its own roots survived with leaveloss. under exactly the same conditions. I will test yuzu on its own roots in future.

Ilya sent me some Poncirus+ seeds two years ago. There was some variation in the seedlings. And I would say there were also tetraploid seedlings. It is difficult though to count the exact number of zygotic seedlings. Most look too similar. They can be zygotic or not.

Batumi Citrumelo has zygotic seeds at least some at least when the right pollen is used. Batumi Citrumelo has a very good taste. But it is sour.

your batumi CM comes from ADAVO?

I have Kabosu from the budwood that I got from Roberto. The leaves are less round and have some suspicious wrinkles.

Ilya, can you remember, when did I send you this budwood? I think it came from a plant I have lost in the meantime. Originally from a Citrus-friend from Germany. Most likely it is not from Adavo (but I do nor know his source)

No poncirus but a hybrid.

Your yuzu is on its own roots or grafted?

Hmmm .... really "in some kind of english" :-) :-) :-) :-)  The automatic translation is totally insane.

All are grafted plants.

I do not know. Perhaps full dormancy of plants without interruption. From the beginning of November until the middle of February, the garden is completely sunless. In this period, the sun's rays will not reach even a minute over the surrounding houses.

Occasionally, the flowers look like roses. The appearance of the USA119 is very irregular.

I am with you: wintersun is a killer. If there is no full sun protection you can forget all stories about hardyness. One of my yuzus was killed by morning sun. Lowest was -6 or -7°C!! The one in the shade is not damaged at all and Hanayuzu which was hit by evening sun has some cracks but will survive (hopefully)

thanks Mikkel, seems I have to regradt some of my Dunstans 😉, because I also see 5* better than Dunstan in taste.

5* is bad enogh! The bitterness is grave and long lasting and there is resin. Nearly as much as with my Poncirus.

The fruit reached maturity by now.




Good fruity smell without poncirus note, juicy, acid,  bitter like calamondin, a little bit of internal oils sticking to the dents.

Thank you, Ilya. Looks very nice! Mine did not flower yet but is a very nice tree with dense round crown (high grafted on poncirus) Maybe this year!

Have you ever thought of Ichang Papeda? Is it suitable for your climate zone?
Ichang Papeda grows much better than Poncirus and some flower after 3 years, but not all.
Poncirus grows so unspeakably slowly that I am already wondering whether it is at all suitable for my climate.

Mikkel,

there is quite a lot of variety with PT seedlings. Some are vigorous others not at all. You have to select the vigorous ones.

Yellow twigs are a sign of some kind of lack of nutrients.

It seems that there are F2-Citrumelos with mono-leaves. The discription of taste does not fit a F1-Citrumelo
