Mrs. Moehrle’s was grown in two locations in 2012 and four locations in 2013.

Growth and Development

Mrs. Moehrle’s Yellow-Fleshed appears to be a mid-late season potato, maturing later than many of the potatoes in the trials.  In Winlaw, BC, Mrs. Moehrle’s took 119 days from planting until all the leaves had died back.  The standard Yukon Gold matured in 107 days and reached all stages earlier that Mrs. Moehrle’s.

Neither potato produced fruits at this location.

Yield

Mrs. Moehrle’s potato was among the highest yielding potatoes overall. In 2012, it yielded well under conditions of severe drought in Victoria, and less well in the high heat-high humidity conditions in Caledon. In 2013, it outyielded both Sieglinde and Yukon Gold.
