My response--------

Yes, there have been several studies which imply validity of the above.
Unfortunately, until very recently, many seedlings which germinated late were
discarded as being weak growers, non vigorous, etc.
If folks down south wanted low-chill and high quality, you might think
about crossing Sundowner x GoldRush.
Just a thought.
