Seven cultivars of primocane-fruiting raspberries (Rubus idaeus L.) were grown for three years in a greenhouse in Simcoe, Ontario. Red raspberry cultivars 'Autumn Bliss,' 'Autumn Britten,' 'Caroline,' 'Heritage,' 'Polana,' and 'Summit,' and the yellow raspberry, 'Anne,' were compared for berry yield, fruit quality, and earliness and consistency of fruiting. Two types of propagules of "Autumn Britten' were used, tissue-cultured and vegetative, and these behaved similarly with the exception of fruiting consistency in the first harvest season. 'Polana' yielded the most,'Autumn Britten' produced the largest berries, and 'Summit' and 'Heritage' ranked highest for total fruit quality. Early and consistent fruiting patterns were exhibited by 'Polana,' 'Autumn Britten' and 'Summit.' [References: 7]
