Pioneer™ Mac

Pioneer™ Mac
(Greiner Cv.)

Ripens just after Rogers Red McIntosh, allowing flexibility in harvest. Fruit quality, flavor and size are excellent. Flesh is white and firmer than many McIntosh strains. Pioneer™ Mac has shown resistance to late-season drop on mature trees. Considered a non-spur, the tree exhibits semi-spur flower bud formation, with some fruiting on one-year-old wood. Tree is less vigorous and more spreading than other McIntosh strains. Pioneer™ Mac will pollinate both Marshall McIntosh and Rogers Red McIntosh. One of the highest quality McIntosh strains suitable for CA storage.

Pollination Charts

Many fruit tree varieties are not self-fertile. In order to have successful pollination, it may be necessary to have two different varieties of tree.
