Yermak is a cold-climate fruit cultivar introduced in 1939 [1], with origin/location noted as season at the North [1]; with reported parentage and in tree the Siberian pear gives e x treme hardiness [1].
Reported parentage includes and in tree the Siberian pear gives e x treme hardiness [1]; Seckel x East Siberian pear [1].
Reported fruit characteristics: flavor/cooking notes include flavor of the native plum especially for preserves and jams [1]; productivity notes include productive [1].
This summary currently draws chiefly from New Hardy Fruits for the Northwest.

“In a 10- year test at the State Orchard at Watertown, on a hill without protection, the Teton was hardier and bore more fruit than other native plums from furher south and east”

“In the fruit, the Seckel, the highest in quality of all pears grown in America, contributes superb quality; and in tree the Siberian pear gives extreme hardiness”
