I might be able to get one of the bioinformaticians at work to build me something in exchange for a case or two of homebrew or tomatoes!
I was thinking a tree like above for the released dwf varieties would be kind of cool on the dwf project web pages. Folks could see the development of the final line released and the variation it came from. I have one I did manually in PowerPoint, of all things, for the Muddy lines to date.
Thanks for the tip on the Access programming book!
