starting my first crosses

[dice]

I once crossed Moravsky Div with Huge Black. I got six seeds
out of the crossed fruit. Looking at them in the fermenting
margarine container, I decided that there was not enough juice.
Rather than add water and sugar, I decided that, "Hey, I can just
use one of these zillion Csikös Bötermö fruits that I have, cut it up
in a strainer, and let the juice drain into the Moravsky Div x
Huge Black seeds."

As I was doing that, I started to think about something else, and
I forgot to use the strainer. Suddenly I looked down and noticed
that I had the seeds of both fruits together in the fermenting
container. Dang.

So I have these six seeds of an F1 cross mixed up with 30 or
more seeds of an OP indeterminate or semi-determinate,
both RL. I have so far not been willing to use up 30 or more
tomato spots in one year to find them. (2 Csikös Bötermö plants
is plenty for one year; they have mild, sweet flavor and produce
like a cherry tomato.)
