A Canadian research group is developing sweet potato varieties better suited for Canadian growers.

The new varieties from the Vineland Station, Ontario-based Vineland Research and Innovation Centre are adapted to Canada’s shorter growing season and climate, according to a news release from the group.

In its third year working on new sweet potato varieties, the center is now doing farm trials in Ontario and the Maritimes.

“So far we’ve screened over 2,500 sweet potato seeds, some of them acquired from our Louisiana State University collaborators, for several traits including flesh color, days to maturity, dry matter content and sugar content,” Valerio Primomo, a Vineland research scientist, said in the release.

The center is evaluating 15 of its top-performing varieties in the trials, Primomo said.
