Stan sent me some US 852 fruit.  As I reported back then, they were much too sour, but the juice was OK diluted with water and sweetened.
Eyecker sent me a (clem x trifoliate) x clem fruit.  It was much better, more sour than I like, but not bad.
So now I've tasted a half mandarine half trifoliate, and 3/4 mandarin, 1/4 trifoliate.  I've tasted only one variety of each type.  Truely this is a sample size too small to mean much.  But in my mind I'm extrapolating anyway.  Very encouraging.

Eyecker also sent 15 Taitri fruit.  Only the best 3 were worthy of making lemonade.  But the 15 fruit contained 500 seeds which are planted.  I hadn't planned to breed lemons, but they are this really big group of F2 seeds to come along.  It will be a chance to look at a big F2 population, unless they are mostly nucelar.  I tend to get ahead of myself.

Walt, I suggest you make an acquaintance in the area who would be able to carry on your long term hardy citrus breeding project if something were to happen to you. You have to think ahead and plan beyond your lifetime.

I have read of many results of long-term fruit breeding being totally lost when the original person carrying on the experiments died. Such a shame. I'd hope that doesn't happen in your case.

Actually I'm looking into forming an LLC to inherit the ground and plants and all rights to them.  My 2 children will be members of board of directers, to help see my plans continue.  But I will need directers who are deeply committed to citrus growing and breeding.  Anyone can PM me if interested.  Or I guess you could write me here.  I'm not trying to hide anything.

Taitri seedlings are finally germinating.  I think they were so slow because we were keeping our house cool to save heating cost.  Now I hope the (clem x tri) x clem will be germinating soon.

Taitri was very slow germinating for me as well. Noticeably so.

What percent of seedlings are zygotic?

I think what you're actually asking is how many of the seeds were not polyembryonic ?
(As you know it's not necessarily such an easy thing to figure out if they are actually zygotic)

Yes, I've learned that first hand.  Some zygotics may look liker their mothers.  And some polyembryonics have delays between first and second seedlings from the seeds.  So I'm hoping for any guesses on what to expect.   Anyone have experience with F2 Taitri?

Recently I printed this thread and re-read it all, marking things I'd missed and should respond to.
Several times I've written that I'll be growing 200 seedlings per population per generation.  Not the same thing at all.  With 9 populations, that would be 1800 seedlings per generation.  But I've decided I won't be doing population 9.  And population 1, pure P. trifoliata, will be a much smaller population.  All I'll be doing with population 1 will combine precocity, lack of nasty ponciris flavor, and high percent zygotic seeds.  That doesn't require 200 seedlings.  So I'm down to 1400 seedlings per generation.  By starting different populations in different years, I will be starting 200 to 400 seedlings per year.  However, I'm now planning on doing it with mandarins and with finger limes.  That means 400 or more seedlings per year.  I can do that.
