Man, did you find any Hicks Broadleaf seeds ?
I was reading an article today which was published in early 70s when blue mold (
Peronospora tabacina) was still a big headache among tobacco growing countries and so for Turkey. I saw that researchers used Hicks Broadleaf to compare its resistance to blue mold and growing behaviour with officially registered Turkish varieties - both resistant and sensitive to blue mold. It was a quite interesting paper so I searched "Hicks" on the forum and saw your thread here.
EDIT: Varieties they used in the paper are Hicks 321 and Hicks 131 and both of them are resistant to blue mold.
