Color genetics of Lycium cross

I'm curious what you guys this will be the potential berry colors in these goji hybrids I'm growing out.  I wonder if its at all analogous to tomatoes, but I'm not very knowledgable about them. 

The seed parent is an interspecies hybrid goji called stardust.  In my climate the berries are translucent purple or whiteish with purple flecks.  The parents of this cultivar are yellow goji x black goji.  So the hybrid is kind of a blend of those colors I guess, it ripens green to yellow to whiteish purple.  Its more purple in cooler climates, but still translucent. 

I crossed it with a goji with red fruit.  Would you expect red to dominate the first generation crosses, or maybe that there is some blending of color?  Probably nobody knows since the genetics may not be analogous to tomatoes, but I'm curious what you all would  guess.

I believe that some mutant Black Gojis seem to indicate that Black Gojis, simply have anthocyanin, like tomatoes or some peppers have.


The mutants are white, if I remember correctly. It's been a while.


Stardust is a cross between Red and Black. It starts out white and turns purple. But, it seems like the purple is a coating.


So, the cross over with the Yellow Goji.


One is supposedly tasty fresh, juicy. The other is black / antho. Anthocyanin seems to work as a coating in S. nigrum and Capsicum as well as in Pepinos.


I'm not sure if it interacts with other colors in the same ways as other species.

Stardust obviously has a different tint to it, than Black Goji. So while it seems like there could be a coating, other genes could be at play. Maybe there's other hidden antho genes in its relatives?





Different antho genes could explain why there's a speckling.



So, they could mix depending on some things.

Tomatoes can have multiple color genes at once, and sometimes that makes a mix. But they usually don't show at the same time, they pair and make something else.


Or only one trait shows. All sorts of stuff.



I'd assume that you could end up with a full on, red goji with no purple. Or a mix of things. It depends on if Stardust is fully stable.

Does that mean there are types of S.nigrum whose berries stay green when ripe? I knew about the yellow and orange ones and I have heard about red fruited ones, but remaining green is new to me. It also means that all of the non-black colors have two variances, one to make the insides some color other than green, and one to turn anthocyanin off in the fruit skins.

It also means an additional potential threat when I grow S. opacum, since if these rules apply to S.nigrum, they probably apply to S. Americanum as well, and final fruit fruit color is one of the only way I can tell the Greenberry fruit from the intrusive American fruit is to see if it is green AND soft.

So I heard the mention of high-antho Lycium. The only black goji I am aware of is Lycium ruthenicum.

Are you aware of any black versions of Lycium barbarum?
