Green Zebra Breeding - Page 2

**Tom Wagner** · August 15, 2007

I've taken a picture of the fruit of Black Brandywine X Green Zebra. The fruit is shaped somewhat like the Green Zebra, but a bit larger. It is the dusky black brown of Black Brandywine with a good tangy flavor. The striping did not appear obvious as I predicted, just a latent undertone of stripes. The maturity was much earlier than either parent, with what looks like great yields to come.

I am taking a few moments to catch up with the PC as I have been moving to a new residence these past weeks. I am way behind in my breeding work. Lots of potato berries to pick.

Patrina, nuclear DNA and mitochondrial DNA (mtDNA) both live in the seed, indeed, in every cell of said seed and hence every cell of the subsequent plant. Except for the gametes of course!
If you are concerned that some trait that you want resides in the mtDNA then using the plant with that trait as female is the only way to pass that info on to the next generation. For many species (we humans included), the male contributes virtually no mtDNA.
Carol Deppe, in her book Breed Your Own Vegetables, talks about this. When she does a cross, if there is no other reason for choosing one over the other as female parent (see Craig's post about choosing recessive traited mother), she chooses the rarer of the two (if that applies) as mother to preserve the rarer mtDNA.
