Mato: This is my thought exactly.
I too started several lines "from scratch," crossing an old standard commercial type with an heirloom, for example; or crossing two old standards known for heat tolerance, etc.
But then I ran across release notices for a few tomatoes developed by professional breeders, and realized they sometimes use other breeders' hybrid cultivars as a base, like Amelia (for TSWV res.) or Blazer (I suppose for heat tolearance).
In the case of Carolina Gold, one parent provides tendency for jumbo size fruit, but is susceptible to weather checking on the shoulders, and some potential for cracking. The other parent provides resistance to those defects. Both parents are based on Jubilee, which as I said can be susceptible to gray wall disorder, as are many yellow tomatoes, including Mountain Gold, an open pollinated predessor and parent to Carolina Gold (which as noted is a hybrid resistant to gray wall).
So yes, why not start with these improvements rather than with Jubilee's potential for known disorders?

I think when we use a commercially released hybrid that still is in circulation, we should at least acknowledge our use of the germplasm in our projects if we share seeds with others.
I do not intend, at this time, to sell the seeds from this project, but I might eventually do that. My initial intent is to develop a high beta carotene, large fruited determinate as a gift to a couple of friends of mine in Anguilla, BWI.
Dr. Randy Gardner comes to this tomato board occassionally. He has friends here as well. I hope he will weigh in on the appropriate way to acknowledge the use of his germplasm (or the use of other professionals' seed lines) when we amateurs use them.
