Anjou: Fruit is average to large in size. Skin ripens to a creamy greenish color and occasionally develops a red cheek. Flesh is mild to rather sweet and fine textured. Excellent late pear for all uses. Fairly good pollinator. Harvest 3 to 3.5 weeks after Bartlett.
Bartlett: The most widely grown of all pears--it is the standard against which all others are judged. Fruit ripens to a yellow color and a medium to large size. Tree is of average size and is productive. Pick third to last week in August in most areas of Pennsylvania. Red sports are available and can be expected to perform the same as standard nonred strains.
Bosc: Large, long-necked fruit that ripens to a greenish yellow, usually completely overlaid with a cinnamon-colored russet. Fruit quality is excellent for all uses. Good pollinizer for Bartlett. Harvest 3 to 4 weeks after Bartlett.
Gorham: Similar to Bartlett in size, shape, and color. Fruit has a shorter neck than Bartlett. Always has russeting around stem end. Sometimes develops a blushed cheek. Flesh is firm, juicy, and sweet. Good for both canning and fresh use. Pick 12 to 14 days after Bartlett.
Keiffer: Fruit is small to average in size. Ripens to a creamy yellow color with many conspicuous brown lenticels. Only use is as a canning pear. Harvest 5 to 6 weeks after Bartlett.
Magness: Medium-size fruit with excellent quality. Pollen is sterile; therefore, you will need two additional varieties for pollination. This variety has some fire blight resistance.
Moonglow: Medium to large, dull-green fruit sometimes having a pink blush. The fruit flesh is smooth and fine with excellent quality. This variety has some fire blight resistance.
Seckel: Small fruit. Tree is small, very productive, and fairly resistant to fire blight. Fruit ripens to deep yellowish brown and is very sweet. Excellent for canning and for fresh use. Poor pollen producer. Harvest approximately 3 weeks after Bartlett. Seckel and Bartlett are incompatible and should not be planted together for pollination.
