Citrus ichangensis as rootstock

[roberto]

is there any information about C. ichangensis used as rootstock? I am looking for a rootstock thas is not sensitive to a higher calcareous level in soil.

I used Yuzu as a rootstock - it works well with high calcium levels. You can also use FA5(trifoliata*cleopatra) and C22(trifoliata*sunki)

From my observation ichangensis and its hybrids are not particularly resistant on high pH soils.

FA5 citrandarin and its parent Cleopatra are more adapted to high limestone/pH/salinity.

Thank you. So I will look out for Forner-Alcaide 5. If I am lucky I can get plants from Spain.

[samodelkin]

citrandarin 84 E P. trifoliata x C. deliciosa Sunki mandarino Sunki x P. trifoliata Fao 30587 - SRA 926 can be bought in Tintori
www.oscartintori.it/prodotto/mandarino-sunki-x-p-trifoliata-fao-30587-sra-926/
FA5 here www.vivaisquadrito.it/614/New-Forner-Alcaide-N-5.html
Citrandarin can be propagated by rooting. FA5 retains properties only when cuttings

[roberto]

FA5 produces zygotic seeds, does it? And what about PTxSunki? I have a tree in my garden. It is really hardy but did not flower yet (after much more than ten years) I grew it from seed.

[samodelkin]

The plant from Tintori preserves leaves in winter, some seedlings are deciduous, some seedlings also winter with leaves.
The fruit is similar to a tangerine 70-90gr, the skin is unpleasant as pontirus. The flesh is orange sour, there is a little sugar, when fully ripe, there is no bitterness. Seeds 10-25pcs

Aleksandr, is it SRA 926 (SunkiXFao PT)? On Tintori site its leaves are quite different.

[roberto]

My plant Comes from seed, has very narrow leaves like shown on the picture. In very cold winters it drops almost all its leaves.

[samodelkin]

On strong shoots, the leaves are large wide trifoliate. On the thin side branches the leaves are narrow long often monofoliate

[samodelkin]

I don't have C. ichangensis seedlings. There are rooted Yuzu from Yalta and Tintori. In my terms(Ph 8-9) Yuzu from Tintori much chlorotic
I assume that Yuzu from Yalta is C. ichangensis + sunki.

[roberto]

Thank you Samodelkin,

very interesting indeed. Tintori's yuzu ist worth Nothing. The fruits are inferior aswell.

[samodelkin]

Yuzu as a rootstock - good growth and no chlorosis. Grafted on Yuzu C. macroptera. I plan to make a tree garden from papeda

[samodelkin]

C. ichangensis x C. limonia var. otaitense (Tahizu)
Tahizu seedlings at Ph 8 grow poorly, half died of chlorosis. Tintori Tahizu plan to graft on Yuzu to preserve the variety. Tahizu fruit resembles Yuzu, but the taste is sweeter, the skin is unpleasant oil, a lot of bones

[roberto]

The fruit looks nice but unpleasant taste of peel sets it behind yuzu. Yuzu-taste is simply great and very sought in Europe.
