Steve,

I forwarded your question to Jim McKenna who is a Juglans and chestnut 
breeder and developer who works for a joint Purdue-USDA hardwood improvement 
project located at Purdue Univ. You would have met him at the fall INGA 
meeting 
you attended, except his personal schedule kept him home. 

His answers are in bold blue.
