Answer
Here are the peach species that Penn State U. recommends for PA. They also say "Currently, no suitable dwarfing rootstocks exist for peaches"


Peach Varieties
The number in parentheses is the number of days a variety ripens before (-) or after (+) Redhaven.

Candor: (-20) The first early peach of the season with any quality, its fruit are yellow and medium in size. A large percentage of the fruit tend to produce split seeds, which limits this variety's usefulness in canning. The fruit ripens approximately 20 days before Redhaven.

Harrow Diamond: (-15) A medium to medium-large fruit with an attractive scarlet-red skin over a greenish-yellow ground color. The fruit is semiclingstone.

Garnet Beauty: (-10) A good early peach that ripens just before Redhaven. Semiclingstone to freestone, very productive, and medium sized.

Glenglo: (-8) This yellow-fleshed peach is attractive, medium large in size, moderately firm and semifreestone. This variety has low susceptibility to bacterial spot.

Reliance: (-6) Developed in New Hampshire, its chief advantage is that it has better-than-average bud hardiness. The fruit quality is only fair, but if growers are on a marginal site in the state for growing peaches, this is the only variety they should try.

Redhaven: (0) The standard and most popular peach variety in the industry. The fruit quality is good, although fruit size may be small if it is not properly thinned. The fruit has above-average quality for freezing but below-average quality for canning. The average first harvest in southcentral Pennsylvania is around August 1. In central Pennsylvania it is around August 8.

Harbrite: (+4) Released from Agriculture Canada at the Harrow Station, this is a productive freestone with medium to large, round fruit. It has good winter hardiness and is reported to have some resistance to bacterial spot and brown rot.

Redkist: (+14) A medium to medium-large fruit with a crimson-red skin. Fruit is firm and freestone. Tree has low susceptibility to bacterial spot.

Beekman: (+16) A red sport of Sunhigh found in an orchard in Boyertown, Pa. The fruit is very firm and of a high quality, and the flowers are very showy and large.

Harmony: (+21) This is a productive, winter-hardy variety. The fruit is medium to large and freezes well. It also is sometimes listed in nursery catalogs as Canadian Harmony.

Madison: (+24) This firm-fleshed, high-quality peach is good for freezing. The trees are more tolerant to frost than other varieties and are recommended in northern areas of the state.

Cresthaven: (+27) The fruit is medium to large, nearly round, and very uniform. The color is golden, overlaid with an abundance of bright red. This is a yellow-fleshed freestone that shows considerable red around the pit. Harvest is approximately 27 days after Redhaven.

Encore: (+30) A large-size, 60 to 70 percent crimson-red fruit with a greenish-yellow ground color. Fruit is firm freestone and ripens in late August to early September.
