Balanced pruning is used to manage vegetative vigor and fruit load to optimize yield and fruit quality in most of fruit species. The objective of this study was to determine the bud viability, yield, and fruit quality potential of four grapevine cultivars using three pruning strategies. Four cold climate grapevine cultivars- -Brianna, Frontenac, La Crescent, and Marquette--were tested with spur (SP), short cane (SC), and spur plus short cane (SPSC) pruning treatments in 2018, 2019, and 2020. The SP treatment was 10 two-bud spurs per vine, SC was five four-bud short canes, and SPSC vines had four SP and three …
