Interstem grafts to evaluate pear germplasm for dwarfing potential

Summary: Interstem grafts on seedling rootstocks were evaluated as way to screen pear selections for dwarfing potential with Bosc and Bartlett scions. After 3 years two selections were identified as possibly dwarfing. However known dwarfing or vigorous rootstocks did not perform as expected, indicating 3 years are insufficient to properly evaluate rootstock potential.
