Freckled Strawberry

I'm still working on the genetics of the trait, but it's distinctive.

Mark, is that the variety Strawberry, as opposed to German Red Strawberry, both of which are heart shaped? I'm asking b'c either that's a big big plate or those fruits are small for both varieties which should be in the 1# range.

Is it a trait you've seen before or has been described before? it doesn't look like Gold Fleck to me and is it heritable or some kind of weird weather checking?

Looks like a cross with Scabitha.

When I got the update e-mail from the various threads and saw that you had suggested Scabitha I went searching to see what the fruits looked like since I hadn't grown it.

Best I can describe what I saw was kind of vertical segmented lines of gold on the fruits which isn't exactly what I see in Mark's picture.

Is there such a thing as vertical segmented gold flecking, and gold flecking can be heritable: Depp's Pink Firefly is one example.

Very interesting nonetheless.

I'm going with Scabitha because Mark has it (that's his hand holding the tomato in the link I provided), has used it in crosses (see Frogsleap Farm on Facebook), and Scabitha exhibits the scabby, vertical scar tissue seen on the scabby Strawberries along with the vertical, gold streaking.

Yep, it's a selection from an unintended cross w/ Scabitha. I have several intentional crosses now too. The trait is heritable, largely dominant, but appears to be "susceptibility" to the physiological condition gold fleck. In this genetic background the "freckles/scabs" are extremely prominent, in others, less so. Carolyn, average fruit size is about the same as a large strawberry.

Mark, you say that Gold Fleck is physiological in nature but what I've read in my Seminis Tomato pathology book as well as online is that Gold Fleck is at least partially heritable b'c certain varieties are more susceptible to it and it is heritable, viz Depp's Pink Firefly etc., and the link above from Seminis, 2010, says the same.

And again I saw where Gold Fleck was usually, but always, associatred with Pox.

When I was Googling just now I found some studies done in FL primarily with some of Randy's Mountain series where it was show that one of them was very susceptible. They were trying to make a connection between insecticide use and Gold Fleck , the thinking was that it was some kind of insect damage, but the results didn't show that.
But you certainly have more experience with it than I ever have.
