Pollinator responses to variation in sunflower crop traits

Several traits have been suggested to influence pollinator choice of inbreds or hybrids of cultivated sunflowers. Recent research has suggested accessibility of nectar, determined by floret length, is the genetically-controlled trait most important to sunflowers’ attraction of wild bees. The importance of nectar accessibility also seems to extend to honey bees foraging in sunflowers. However, there are cases in which the “shorter is better” rule for floret size may not apply, or cases in which floret size may be unimportant. Progress in understanding exceptions to the rules on pollinator preference and progress in mapping plant traits will be discussed.
