There are no thornless black raspberries that are currently available in 
North America.  All of the old cultivars have been lost.  There is a new 
cultivar in New Zealand that is thornless, however most of us working with 
black raspberry consider it to be more of a purple as its thornlessness was 
derived from crossing with red raspberry and despite several generations of 
backcrossing the fruit still retains a purplish color.
 
There is currently work on breeding thornless black raspberries.  In addition 
to incorporating thornlessness from red raspberry, we found a few sources of 
wild plants that grow thorns only at the base of the canes (~8 inches at the 
bottom) and occaisionally on the petioles in the collection that we assembled 
a few years ago.  There were some selections made from those and crosses as 
well as the first round of crosses, but it will be several years before any 
new varieties are named and released from this material.

Subject: [nafex] Thornless Black raspberry

Does anyone know of any Thornless black raspberrys that are available.  All 
the cultivors I have located are lost to us: Why would they be ignored?   
Davison was suposed to be very good. Others were: Springfield,Ada,Fay's 
thornless and Early prolific
Thank you 
Larry D. Cook.

I buried the graft-union of the bellow trees.  I did this to avoid the 
potential for (future) graft-rejection (however, unlikely in these cases), do 
avoid the entry of borers (at the graft-union, if present), and so that the 
suckers (in the cases of those which do sucker) will be that of the scion 
variety:

Would you mind providing more information regarding what you hope to
achieve?

My experience with the stone fruits you mention (Peach, Nectarine,
Apricot and Plum) indicates that high quality fruit can be obtained w/o
grafting. (The only source for reproducing a complete organism is the
seed.  Slips of many varieties will root but the results are less
impressive than those obtained from seed).

Otherwise, the use of specific rootstocks responds to specific goals
(resistance to a specific disease, increased take-up of certain
minerals, dwarfing etc.), although the trade-off is metabolic imbalance
in the grafted tree and it's fruit (one problem is resolved but another
is created).

Respect for the integrity of the individual organism provides a good
foundation for understanding the needs of the fruit producing plant - a
good place to begin.

Are you sure you really want to graft in the first place?

In each of the above cases, the caliper is not much greater than 1".
