is Del Gold a hybrid?

I have a lot of cobwebs in my brain on this one but I think it was developed in Canada ( in the 80's?) by crossing a Rustica with a flue cured Virginia and one other variety. It is supposed to have a lot of nicotine. I would guess that it breeds true.

Del gold is not a hybrid. It breeds true.
"Delgold is a superior flue-cured tobacco cultivar developed at the Agriculture Canada Research Station, Delhi, Ontario in 1980 by crossing wild tobacco (N. rustica) with two popular American varieties, Hicks Broadleaf and Virginia 115. The result was a high-yielding, high-nicotine cultivar that was widely adopted by growers. Delgold is still considered one of the better yielding flue-cured varieties available."
I am not positive but I think I read somewhere that the nicotine content was around 5-6/mg per/gram of leaf.

How did they cross rustica to tobaccum? I thought deluxe used the inability for a rustica to cross to tobaccum as a way to prove that a variety that was thought to be rustica wasn't.
Of course it was a lab, and labs can practically cross corn to fish....

N. tabacum pollen is capable (at a notably low success rate) of pollinating N. rustica, though not the other way around. In my small sample size, my success rate was near zero. I had one runty Cornplanter seed pod struggling to develop from Mt. Pima pollen, but it dropped off the plant before maturing. So yes, it's possible, but a challenge.

i've got a link to a study that was run in one of my posts where they clocked it in at a little above 3%, the reason it really shines though is because it is such a heavy producer so the pta was the highest in the study.
in the study they found a relationship to the total alkaloids as going down as the plant size increased, which also explains why most rusticas are low producers.
