Hybrid = F1

If you save seed from F1 and grow out, the resulting plant is an F2.

From Sungold, you would expect red/gold cherries of a variety
of sizes.

Sungold Select and Sungold Select II are open pollinated versions that are very similar to the hybrid version.

I hear a Sungold Select III is in the works, but nothing
quite compares with the Sungold's unique flavor.

Good one John but I think you should have clarified that to indicate the stability you were referring to was the instability of F1 hybrids that makes money, not mental or physical or social stability. LOL

Carolyn

Mental stability doesn't make any money either....I still have to work.

Can I un-hybridise Sungold by planting seed from F1 and selecting spacific qualities?

Will the plants produced from planting seed from F1 be an open pollinated variety?

Can I determine the parents of an F1 using the above?

You certainly can try, but many have gone before you in trying to do that without much success. Please note that in a post above Lee mentioned that there already are two decent stable OP derivatives, and I had posted elsewhere that a Sungold III was in the works as dehybridized by Reinhard Kraft in Germany, who also did Sungold Select and Sungold Select II that Lee mentioned.

(Will the plants produced from planting seed from F1 be an open pollinated variety?)

No. An OP selection is only OP when all seeds saved give rise to the same plants/fruits. That is, plant out some F2 Sungold Seed and you're going to get some red ones and some yellow/orange ones and they won't all be the same size and they won't all taste the same. So you make a selection, save those F3 seeds, plant out, make a selection and on and on it goes until as I said above, all seeds saved give rise to identical plants.

It usually takes several F generations, from maybe 4 to 7 to get a fully genetically stable OP. But that also depends on the genetic background of a variety, which of course for Sungold no one knows what the genetic input was to breed it, save what I say below.

(Can I determine the parents of an F1 using the above?)

No. Modern hybrids have many genetic inputs, they aren't the result of crossing two varieties as was common with much earlier varieties such as Big Boy and Better Boy and Ramapo, all hybrids.

All you know is that any variety with flat trusses such as Sungold have the currant variety S. pimpinellifolium gene bred in them that determines the flat truss trait.
