This article appears in the November 2019 issue of Potato Grower.

La Belle Russet is an early- to medium-maturing variety with good early-season yields of oblong-long, medium-russeted tubers with a long tuber dormancy comparable to that of Russet Burbank. It is notable for its production of attractive tubers produced in varied growing environments across North America, resulting in a high percentage of marketable yield.
