What is Pollination?
• Transfer of pollen 1. Self-pollination (autogamy)2. Self-pollination
(geitonogamy)3. Cross-pollination
(xenogamy)

BlackberryRubus fruticosus
• Breeding System: self-sterile to partially self-fertile
• Pollination System: wide open flower accessible to many insects; cross-pollination by insects needed
• Pollinators: many kinds of insects, honeybees
• Notes: loganberries, youngberries, boysenberries and dewberries are various Rubus spp. and hybrids with raspberries (Rubus idaeus)

Lowbush BlueberryVaccinium angustifolium
• Breeding System: mostly self-sterile
• Pollination System: buzz pollination by many kinds of wild bees
• Pollinators: wild bees, bumblebees, honeybees, leaf cutting bees
• Notes: self-fertility seems more common in isolated small populations; hugely important wildlife food (black bears, migratory birds)

Highbush BlueberryVaccinium corymbosum
• Breeding System: mostly self-sterile; questions of varietal self-sterility vs. within plant self-sterility
• Pollination System: buzz pollination by many wild bees; flowers differ in size, depth and opening by variety so restrict access to some pollinators
• Pollinators: many wild bees, bumblebees, honeybees, leaf cutting bees
• Notes: Some varieties require other pollinizer nearby, others need cross-pollination between plants of the same variety

Haskap = Blue Honey SuckleLonicera caerulea
• Breeding System: cross-pollination between varieties is required (self-sterile)
• Pollination System: tubular flowers offer nectar to bees with longish tongues
• Pollinators: understudied; probably well served by bumblebees; honeybees can be used

Conclusions
• General pollination requirements for berry crops are well to poorly understood
• Most indications are that having adequate pollination by insects is important to maximize yields (grapes excepted)
• Breeding systems need to be elucidated by species and cultivar in almost all berries
• NSERC-CANPOLIN’s first target will be blueberries
