The Tropical Fruit Forum

The Nansho Dai Dai fruit I have tried are very sour, much more so than Rough Seville Sour Orange. Possibly Gou Tou comes close, but not quite.
As for the foliage there are other "Willow Leaf" Sour Oranges and also Sweet Oranges with long narrow foliage.
Willow leaf variants could be possible ?
The type in Australia probably came from UC Riverside collection.
Citrus miaray, from the Phillipines is pretty close to Citrus Taiwanica.

Not sure if the original question is any more clear now, possibly info about the fruit flavours of the variant types, and in Taiwan would help.

The Taiwanica type here is a very attractive tree, with its narrow foliage and the way the fruit hangs in it around the outside.

Take a minute for us in Australia.

I have Fruit Fly in my Loquat fruit.
Lorikeets eating my Loquat Fruit.
Locusts under my Loquat tree.

Is that a Haiku ?
Or a Limerick ?

All this due to changed weather patterns.
Not getting the cold winters so much any more, so fruit fly can overwinter.
Not sure where the Lorikeets came from, only turned up in the last ten years.
Not really complaining about them, beautiful birds, but they can mow thru a fruit tree.
The Locusts, didn't see so many this year, but there was an nymph alert from the Plague Locusts Commission ( a dedicated area of Govt here).
There was a Locust plague some years back, filling the sky. This year it was Dragonflies like never before.

I had one Loquat seedling come up in a shade house, it fruited and missed the fruit fly that got the outdoor trees.

ls there any reason to think that the Taiwanica from Adavo and Lenzi are really Taiwanica, and not just something they grew from seed and marketed ?
They have a multitude of interesting Citrus on their websites, but some clearly don't match original descriptions from elsewhere.
I grew Taiwanica from seed, seedlings seemed highly identical with narrow leaves etc.
One occasionally fruits, but the fruit is closer to a mandarin than the original Taiwanica fruit.
The seed came from a collection, and the next door plant was a mandarin.

Another good point about Calamondin is that it is reasonably fast to fruit from seed, maybe 5 years, certainly not 15.
The plant is on the smaller side, so possibly the node count for flowering is lower ?
It doesn't take too many growth seasons to get to full size
Either way you won't be waiting those long years for the hybrid to flower, depending on the other parent.

I remember reading about another Phillipines variety Calamandarin.
I think both it and Calamondin were also used as rootstocks over there.
Interesting that other Calamondin hybrids are not well known or heard of, even though Calamondin / Kalamansi is cemented in Philippines culture.

The success rate of hybrids is an interesting question.
If the rate is low, you have a few much wanted plants to deal with and a bigger bunch of unwanted plants to deal with.
You may be able to use these as rootstocks for the hybrids ?
I have found it nearly essential to graft from hybrids to ensure survival long term.
(Some of my most interesting unusual off type seedlings now only survive on rootstocks, the originals often died.)
Also you can easily then multiply a few hybrid seedlings to many seperate plants on rootstock.
Grafting to other more established rootstock will also push the hybrid to flowering faster by growth alone.
After that you can either repeat the hybridisation cross, or just grow the next generation seedlings of the first hybrid to get more variable " hybrid " types.
That might be more interesting if they are zygotic, as you are reshuffling the original hybrid cross for new versions.

If the hybrid success rate is high, you have a lot of plants to deal with, pot up, possibly graft, and assess long term for worthwhile characters.
I am pretty sure professional breeders throw out a lot of interesting stuff that doesn't meet the original reason for the  hybridisation cross often based on arbitrary reasons.

I am going to fudge the answer.
I think I am allowed to as you said " when you're hungry and you don't want processed food "  ( ie Fudge )
Coconut, so versatile many stages and uses.
Pistachio and Cashew.
Green Flageolet Beans, Black Turtle Beans,
Lime, Durian,
Chempadek, Marang, Pedali.
It may shock some on the forum, but the roasted seed of these Artocarpus are very nice too, crab like flavour.

The way of grafting Citrus in Japan, and the tools used are different to the West. ( Kogatana knife ?). Also different tape ?

I always thought that pure glauca is 100% zygotic.
Are these plant some sort of  hybrids? They look amazingly uniform in appearance.

With other species, ie Eucalypt, Acacia, Syzygium, etc grown for environmental replanting, the bulk seedlings are highly uniform, more so from one seed tree.
Between seed trees there can be visible differences in the seedlings.
For forestry, some selected seed trees give highly uniform seedlings and reliable final tall straight timber trees.
I would guess most of the above would be zygotic.

Hydrogen Peroxide is added to drip irrigation systems to combat the bacterial biofilms in the irrigation lines. It is also used on cucumber farms to enhance growth and combat root disease. There would be a rate it is applied at, that might give you something to work with.

I shall try that. I have moss (the common type from the lawn),

Do you mean the moss that grows on rocks or damp places ?
Peat moss refers to bog peat, harvested from a wetland area, usually produced by the breakdown of reeds and sedges ( marsh plants ) underwater.

With the polyembryonic mango seed, if the patent applied to a mango variety with the characteristics ABCD, the clonal seedling would also have the characteristics ABCD and would be indistinguishable for patent purposes. A zygotic might be ABCd if you are lucky, who knows if that would infringe the patent. I guess it becomes ABCD$$$$$ vs ABCd$$ ??
I hear there was a case in Australia with giant blueberries where the patent holder took action against another grower who started growing "a Version" of the original.
Those are the developer growers words, so he wasn't explicit on the how and why.
It probably comes down to the level you are operating on.
Some may recall the music file downloading cases where major music companies went after teenagers who " illegally " downloaded music, in test cases or to set an example.

Yuzu is used extensively as a flavouring in Japan for all kinds of products from Ponzu sauces for cooking stock, to snacks and candy.
There was a one off version of Yuzu Doritos corn chips some years back as a promo, other Yuzu snack chips are available.
My local Asian grocery had cans of Yuzu soft drink for a while ( also Kabosu ). Mainly for Japanese backpacker seasonal farm workers, along with other Japanese groceries.

Yes the article is old, more for info about the Fruit Tree research stations in FNQ, ( FYI ).
The archives might be good to back track varieties you are looking for.
Here is a FB page for RFC in FNQ, now called Rare Fruit Australia.

It has good properties as the female parent. It reliably sets and holds fruit normally without much trouble.
It has genes from Mandarin type Citrus and Fortunella. If You pollinate from a Citrus distant from these two, the hybrid will genes from 3 Citrus groups
The fruit are sour but without unusual off flavours.
It is said to be nucellar, but I have also got variable seedlings from Calamondin, not crossed, just interesting variations.
