Dear Plantnetters

I am looking for an expert on horseradish genetics.  Does anyone have 
information on horseradish breeding?  From what I can gather, two commercial 
spp. are being used, viz. Armoracia rusticana and A. lapathifolia.  Also, two 
"types" are being mentioned, the "common" type and the "bohemian" type.  These 
two types apparently have different leaf morphologies?  Are they 
representative of the two species?  Are there any other species, and if so are 
they being used in commercial breeding?  What I am really getting at is, what 
is the genetic diversity in cultivated horseradish?

Any help would be greatly appreciated!!
