Genetical studies of monosomic types of nicotiana tabacum

[Aaron]

Where I work I'm required to stay near my computer terminal and phone all day. So, while I'm standing here doing nothing but waiting, I like to try to expand my knowledge on all things tobacco related. Today I stumbled across this article. It's over my head and I'm slowly making my way through it, but I have to look up a lot of definitions as I go. Anyways, thought y'all might find it interesting too.

gotta link?

Ya, sorry about that Jitter. I edited it.

I'll be having significant portions of page 286 tattooed on my forearm, for quick reference.

Thanks for the article Aaron. Some of the contents are over my head also, but since I have been reading up on genetics lately, this article is expanding my knowledge of tobacco on a more scientific level.

Aaron,
Thanks for posting the article by Olmo (1934). After reading it, I would say that it might be of interest to geneticists and to home tobacco growers with a strong background in genetics. I see no particular application of the info to what most home growers currently do or might want to do. Don't get me wrong. Olmo does tickle me. But the study might be considered an exploration of intentionally induced genetic aberration of no practical value to non-geneticists. It's most interesting conclusion is that large-scale genetic deficits (major screw-ups), in the form of an unpaired chromosome, are much more likely to be transmitted by the female (pistillate) contributor, when compared to transmission by the male (the pollen).

If you double a haploid plant, you get a homozygous diploid in theory with zero genetic variability. The seed it throws should be identical to the parent plant.

Useful if one can find a knockout plant among the monosomatics, that doesn't occur that frequently in the population, etc. IE you can fix the genetic traits in one go.
