Annual Report for NC-140 Committee Meeting.


Blatt, S. 2021. Annual Report for NC-140 Committee Meeting, virtual Zoom meeting, November.

Résumé en langage clair

Apple trees are a combination of rootstock and scion. The rootstock can influence how resilient the tree is to changing temperatures, freeze events and disease while the scion is specific to the cultivar, such as Honeycrisp. Several breeding programs around the world strive to breed rootstocks that will enhance the ability of cultivars to grow across a wide range of climate conditions. Nova Scotia is one site of over 30 scattered across the United States, Canada and Mexico which are evaluating different rootstocks for their ability to produce high quality apple. Two plantings are located in Nova Scotia, Modi (with 10 rootstocks) and Buckeye Gala (with 8 rootstocks). Trees are evaluated for how well they survive each year, how much they grow, how many fruit they produce and what size. All of these variables are taken into consideration when a grower is deciding to use a particular rootstock for a new planting.


This report summarizes the data obtained during the 2021 growing season from NC-140 regional rootstock trials planted in Nova Scotia. There are 2 plantings currently active: Modi apple, located at the Kentville Research and Development Centre, and a Buckeye Gala apple planting, located in Aylesford and hosted by a commercial grower. The trees continue to perform well with some rootstocks showing promise for our climate.
