Description:
The source population was 29 seed collections made from three areas in central Utah (1395 to 3288 m above sea level). Fifty plants from each collection were evaluated for three years for winter injury. Based on this evaluation 24 total plants (23 plants from ten of the collections and 1 plant from the cultivar Potomac) were selected for lower winter injury. The twenty four plants were clonally replicated to a polycross nursery. The resulting seed became USDA-UTWH-102.
