Jp. Prive et al., PERFORMANCE OF 3 PRIMOCANE-FRUITING RED RASPBERRY CULTIVARS IN ONTARIO AND QUEBEC, Journal of the American Society for Horticultural Science, 118(3), 1993, pp. 388-392
The influence of genotype x environment interactions on the performanc
e of 'Autumn Bliss', 'Heritage', and 'Redwing' primocane-fruiting (PF)
red raspberry (Rubus idaeus L.) cultivars was studied at six sites ac
ross Ontario and Quebec during 1989 and 1990. Cultivar x location x ye
ar interactions were found for most vegetative and reproductive compon
ents analyzed. 'Autumn Bliss' had the most consistent performance of t
he three cultivars in all location/year combinations, while 'Redwing'
varied greatly between environments. 'Heritage' was always the latest-
bearing of the three cultivars and failed to achieve its maximum yield
potential in many of the northern locations.
