Yes, Kinkoji (Bloomsweet) is a hybrid of pomelo with tangor Kunenbo-A ( sweet orange - Kishu mandarin cross).

In general, why would anyone support Monsanto???

Here the generic glyphosate is much cheaper than RoundUp.

If you try this post back and tell us how you came out.  I will also try it.

Strangely enough they are not showing the resulting roots  after this "rooting", only partially rotten potato.

At least I bought it from Bernhardt Voss under this name.
He propagated Bloomsweet seedling budwood grafted on poncirus and it seems that the first flowering happened in  my garden. Other than shape it fits the description of Kinkoji/Bloomsweet.

The gas is ethylene, not ethane. It is a naturally produced plant hormone for fruit ripening.

My Bloomsweet is doing beautifully till now. On PTFD, north exposure, it is dealing beautifully with cold snaps we had till now (Temps ranging from 30 to 24F). It is the biggest
My main concern is, if it remains so vigorous probably the place where i though it could be planted will be too small. I hoped to have a plant no taller than 2,5/3mt (8-10ft max).

Pancrazio,
The mother plant of your graft is now almost 4 meters high, but columnar in shape.

Last week harvest:


Very good taste, completely ripe, sweet with some pleasant acidity, practically no bitterness, for me it is better than most of conventional grapefruits

 

Zafra,
Please read carefully wiki article on Cam sanh:
Classification
This tree is referred to as the "King Tangor" or "King Mandarin" in most horticultural literature.[3] Scion for grafting is available through the University of California Citrus Clonal Protection Program.[4]

This Vietnamese  variety is known as King tangor in the West

There is even an article on it in Wikipedia:
https://en.wikipedia.org/wiki/Cam_s%C3%A0nh

According to the recent molecular DNA analysis  Indian limes have a very different origin than Citrus aurantifolia.

Why in this case limes are practically absent in commercial planting in Florida?

Shah8,
I agree with you, people are probably expecting too much from existing poncirus hybrids.
Still, it is amazing that that after more than 100 years of selection, only few hardy and edible varieties emerged.
Nevertheless,  the existence of plants like Thomasville and Dunstan demonstrates that it is possible to shift citrus belt to the North.
I guess  not enough efforts were made in crossing direct poncirus hybrids among them; their crossing to classical citruses diluted the hardiness , but rarely  brought  good quality of the fruits.

Very strange  warning at the end of this article:

Satsuma branches have thorns, so be cautious when handling them

I have never seen thorns in satsumas.
