Crossing and Bridging with Solanum peruvianum

[Justin Jardinier]

Reading the book Organic Crop Breeding. It says that embryo rescue is considered not ok for organic breeding with some exception for older varieties like Owyhee, Payette, and Doublerich.

That to me seems really strange. Was that given as a personal opinion of the author, or as an actual US law position? I could understand the former (though I would completely disagree with it), but I'd find it hard to understand the latter.

Hard to tell for sure but the book is international circa 2012 with one editor from Europe and one from USA. So I would estimate it to mean consensus international organic standards. Though with your current methodologies not involving embryo rescue you would be ok.

Hmm, I'm seeing debate on this in the US and EU around 2020 or so. SUch as in this paper:

And here:

Hard to find what the actual law is though. In this document, Bio Suisse — Standards for the production, processing and trade of "bud" products - 2023, on pg 73 it shows embryo rescue being allowed for organic standards. In the forward it seems to be saying this document is in accordance with EU law:

The present revision and adaptation of the Bio Suisse Standards regulates inspection and declaration in accordance with the requirements of
the Regulation on organic agriculture of the European Community and
the Organic Farming Ordinance

But since I do not have material that has used this precious technique (which I feel should be allowed and so no reason for it not to be), I will end my search there for now.

IFOAM decided it was an ok method in 2018. So the 2012 books is no longer accurate!

I have 3 solanum peruvianum. 2 are located in the veggie garden but the other is in a pot. They all flower big time and bees and Bumblebees love the flowers. I tried several tomato crosses with peruvianum as the mother plant but no succes as was stated in this forum. But then i saw a small fruit forming on the plant in the pot but its located more then 200meters away from the other 2. Did it self pollinated or did it cross with hybrid tomato ? The other plants in pots are habrochaitus/tomato and habrochaitus.

Solanum habrochaites is supposed to work as a pollen parent sometimes just like S. Penellii
