Blackberry and Raspberry Research Trials

LINKS to scientific publications of interest to growers:

‘Von’ blackberry
‘Nantahala’ red raspberry
Primocane-fruiting blackberry study (effect of rowcovers on primocane fruiting blackberry yield and harvest dates)

The documents below contain charts and data that reflect the yields of primocane- and floricane-fruiting blackberries and raspberries from trials at research stations across the state. Data include yields, marketable yields and berry weight for multiple varieties. Prepared by Dr. Gina Fernandez,  Absalom Shank and Rocco Schiavone.

Piedmont Research Station – 2014 

This document has yield data for black raspberry, primocane-fruiting raspberry, floricane-fruiting raspberry, and floricane-fruiting blackberry yield and harvest dates. Black raspberry data was collected outside of tunnels, all others were inside tunnels.

Piedmont Research Station – 2008-2010 

This document contains extensive yield data and harvest dates for 6 floricane-fruiting blackberry cultivars, 8 floricane-fruiting raspberry genotypes (including NC430 aka ‘Von’)and 10 primocane fruiting raspberry both in tunnels compared to out of tunnel production. 

Upper Mountain Research Center – 2010- 2012 

This document contains extensive yield data and harvest dates for floricane-fruiting blackberry cultivars,  floricane-fruiting raspberry genotypes, primocane fruiting raspberry  and primocane-fruiting blackberries both in tunnels compared to out of tunnel production. 

Mountain Horticultural Crops Research and Extension Center – 2010-2011 

This document contains extensive yield data and harvest dates for floricane-fruiting blackberry and floricane-fruiting raspberry genotypes, both in and outside of tunnels. This includes Von and numbered selections from the Univ Arkansas. 

Piedmont Research Station and Oxford Tobacco Research Station (PPT)– 2011 

Caneberries and Tunnels Research Update (PPT)

This presentation shares information about how different varieties of blackberries and raspberries perform when grown in high tunnels. Originally presented by Dr. Gina Fernandez, N.C. State small fruit specialist, at the 25th Annual Southeast Vegetable & Fruit Expo in December 2010.

Blackberry and Raspberry Harvest Data – 2008 & 2009 (PPT) 

This document contains charts and data that reflect the yields of floricane fruiting blackberries and raspberries from N.C. State research trials at the Piedmont Research Station and Oxford Tobacco Research Station. Data include yield, marketable yields and berry weight for multiple varieties. Prepared by Dr. Gina Fernandez and Absalom Shank.

The data was collected by NCSU and NCDA&CS personnel from these locations:
Piedmont Research Station in Salisbury, N.C.
Mountain Horticultural Crops Research and Extension Center, Mills River, NC
Sandhills Research Station, Jackson Springs, NC
Upper Mountain Research Station, Laurel Springs, NC.
