They look identical to my Miyagawa. The fruit should be ready by now though, mine are long gone.

Thanks Laaz!
I'll label it as Miyagawa.

Laaz, question if I may. Why are some variagated citrus' fruit also variegated, but other variegated varieties do not produce variegated fruit? Just curious if variegation is expressed in more than one way? Dr. Manners, do you know??

Patty that's a good question & maybe Dr. Manners can explain that.

Here is another one from Europe. Very cool citron.

Also on my variegated sour orange from UCR, only some of the leaves & fruit are variegated.

Interesting, Laaz. I wonder if there are different ways variegation can be expressed. I see some subtle differences in your various variegated cultivars, so wondering if maybe there is more than one way variegation can occur, and thus that difference might explain why some fruit is variegated, and other variegated cultivars will never have variegated fruit. I wonder if there is anything written about citrus variegation out there? Possibly, just not sure where to search or how to search to find it. Being a nurse, having a science background, I find this very interesting.

You can find (nearly) everything in the "Citrus industry".
Make a search we already spoke about variegation.

Sylvain, do you mean Florida's "Citrus Industry" magazine? It may have that information. Somewhere. But, I don't see a Search feature, so no way to find the info, short of looking through every past issue?

"The Citrus Industry" is a four volume set published in 1948. Written by Batchelor and Webber with the collaboration of 14 or so other professionals. Many people regard the 4 book set as the Bible of Citrus. On rare occasions, they can be found on the Internet from rare book dealers such a Abe's Books, where I found two of the volumes. When found the price is usually quite high. By diligent inquiring I was able to finally purchase all four volumes some time back. - Millet 91

Oh gosh, thanks, Millet. I think somehow I have one of the volumes in electronic format. I'd completely forgotten about this set of I'd love to find the set, I'll have to start watching for it. I did read one of your very well-written descriptions on another forum about variegation, Millet, and that was quite helpful. I just would like to read about it in detail. I'll struggle to get through the technical language, but definitely worth trying to acquire, no doubt.

By the way, there is an online edition of this book (its 1st, 2nd and 5th Volume), hosted on UCR website.

Patty, I made the search for you :

Here is an interesting experiment made by Terry:

Here is the Citrus industry quote:

But none of this explains why the foliage is variegated, but not the fruit.

It could be that the rind is made of two layers and the variegation is in the third. Just a supposition.
