difference between acid-free orange seeds and other oranges.

[Lauta_hibrid]

I just realized there are big differences between the tangerine orange (that's what it's called acidless here) and other oranges. Here we have three types of seeds: the Argentine acidless, the oak orange, and the cara cara orange. The odd thing is that the acidless is white, smooth, and rounded. Could the genetic difference be greater than just a mutation in acidity? Do you have any information on these varieties?

What is the oak orange?

I'm not sure we use the same names here in the US. When you say acidless orange are you talking about sweet lime?

The "Roble" orange is a variety that a grower and collector friend gave me. Other names may be used here in Argentina. The acid-free orange is an orange; there are several examples in the Riverside collection. Here, it has a somewhat illogical name because it's called a "tangerine orange." In Brazil, they call it a "lime orange" because it tastes similar to another acid-free fruit, like the Palestinian lime. I don't know if anyone has an acid-free orange to compare the seeds with, since they seemed very strange to me.

Ah! Now I get it. We do have an orange that we call Robel here in Florida. And, Robel means "Oak." I never made that connection before. The seeds that you are describing (rounded instead of the typical angular seed for a sweet orange) would indicate to me that this acidless orange has a little different genetics than the typical sweet orange. Beyond that I can't tell you much since I am not familiar with this particular citrus.

Your "acidless orange" is probably something else.
I have two of them- Meski from Tunisia and a French variety Gosset, their seeds do look exactly like those of a normal sweet orange.

When you harvest your acid-free varieties, I'd like to see their seeds. It seems like a minor detail, but I saw that some variety descriptions mention seed characteristics, and now I see that it could be important. My interest also stems from the fact that when they published a study that talked about acid-free fruits and their heritability, it seemed that the acid-free orange they had used was chimeric, and when crossed, a hybrid with normal acidity emerged. I'd like to use this one for pollination, and for them, all its parts must have the same genetics. I'm going to see if I can use it to cross with Poncirus and with Chinotto.

I read a part there that says seeds have no color 😅. I need to reread it carefully to understand it in detail and see how to use it. But thanks, because I read it a while ago and didn't know how to find it.
