'Double Delight' is a primocane-fruiting (fall bearing) red raspberry
(Rubus idaeus ssp. strigosus (L.) Michx.) cultivar, developed by the A
griculture and Agri-Food Canada, Morden Research Centre (MRC) breeding
program. This new cultivar is specifically adapted to colder prairie
regions of Canada and northern USA. 'Double Delight' typically begins
fruiting earlier than 'Redwing' or 'Heritage: cultivars generally cons
idered too late for commercial fall bearing production on the Canadian
Prairies, and approximately 10 days later than 'Red River a recent in
troduction from the MRC program. 'Double Delight' is intented to diver
sify commercial raspberry production since relatively few cultivars ar
e suitable for the harsh prairie climates.
