    Re: N. Tabacum x N. Rustica

    The table is indeed an interesting one Bob. Whereas I'm aiming at the N. rustica x N. tabacum for now, the other possibilities are very interesting too, and some of them possibly much easier to establish. I'm not quite sure what other hybrids you think might produce leaf that can be smoked? I'm not very educated beyond the tabacums and the rusticas of this world.

    Delgold: A New Flue-Cured Tobacco

    This is an article on the tale of Delgold, prviously highlighted by ChinaVoodoo. Now besides that it is a very very interesting experiment with outcome by itself, it is especially interesting regarding the cross I'm attampting to make. Delgold was created by a series of crosses. The first cross involved N. rustica x N. tabacum. The N. tabacum used was Virginia 115, and the N. rustica they used was Babor. The hybrid they obtained from this cross was not producing seed by itself. To get seed from the F1 they had to make backcrosses with N. tabacum, for which they used Virginia 115 again. They call these generation BC1. Most of the plants in this generation were bushy and did not produce seeds by itself. They made another backcross with N. tabacum, this time to a Hicks Broadleaf variety. This BC2 was then crossed back to Virginia 115 to create a BC3. A single plant from this generation led to Delgold. To make a stable variety, it had to be selfed multiple times.

    The remainder of the article is mostly concerned with the phenotype of Delgold in comparison to that of Virginia 115. It also shows a picture of Delgold. It's an interesting read, but I won't go into detail about the comparison of the two plants. For now, my point of interest is the fact that they were able to make a hybrid, and make it fertile again. My intention is to create a plant which looks a little bit more like an actual hybrid, rather than only obtaining a higher alkaloid level through crossing with N. rustica. No, my plant should look like a real hybrid!

    I'm pretty drunk. Forgive me. Pulling a Chicken move. But that pdf on Delgold doesn't express the true hardship involved in making Delgold. It was like back cross x a gazillion, hundreds of mortalities. Crazy crazy science. It's elsewhere in the forum. You've probably seen it.

    I'm not saying it can't be done again. If there's anyone who can do it again, it's someone like you who works for a tobacco company, but seriously, man, I'm just saying, make that move with pride.

    Yes I know. As was said in the lethality article, most authors focus on the successes they've had, not on the failed attempts. I do realize it will not be something achieved overnight. Perhaps, I won't achieve anything at all. But just the thought of giving it a shot excites me tremendously!

    I think it's really cool. I would love to see you succeed.

    I haven't done enough research to say I'm correct, but it seems to me that the best tobacco research that's publicly available is the Canadian research. Google half of the Canadian varietals, and you'll find some really interesting documents. Not saying the American research was not great, just not as easily obtained. The Canadian research seems to be intended to be public from day one because socialism, while U.S. Research is private because capitalism.

    I would say that you don't find much on a lot of USA research is because the research belongs to the Big Tobacco companies and is under lock and keys like their trademark casings that they add to their products .

    Re: N. Tabacum x N. Rustica

    I most say that I think that Bigbonner have a big point on that. I have a similar problem to get information about a old time Swedish tobacco variant. I believe that I can find information both about the variant and around that variant but the biggest problem is named COPYRIGHT. often a pretty good thing but in this case it's pretty bad and silly. So you guys might have the same problem. No one cares about some of the studies but they have a copyright and don't just drop information. In other cases they know about studies and they really need to keep the information..

    Re: N. Tabacum x N. Rustica

    It's partly that, but it's also that a lot of people seem to have lost interest in tobacco. Now research on the plant is a very different thing from smoking the leaf. Nevertheless, some of it goes hand in hand. It just isn't the most popular thing around anymore. Let me see if I can dig up a few more interesting articles before my plants have grown to adulthood...

    The "tobacco truth" archives after the lawsuits have quite a bit of information if you haven't seen it yet.
