Serviceberry biotypes in North Dakota: new woody edible ornamental trials
Saskatoon serviceberry (Amelanchier alnifolia Nutt.), or simply serviceberry, is an ornamental shrub that produces high quality, berry-like pome fruit, and is often compared to blueberry (Vaccinium spp.) in appearance, nutrients, and flavor. A member of Rosaceae, serviceberry produce delicate, white flowers that create an aesthetic and naturalistic look in plantings. Most serviceberry are propagated in Canada. However, imported stocks are often expensive and reduced quality. In 2007 and 2008, clones were accessed from over 70 locations throughout North Dakota and proliferated in tissue culture. Following establishment, North Dakota State University (NDSU) associates planted replicate field trials of these biotypes and named cultivars with the intent of introducing edible-ornamental North Dakota cultivars. Yield data were gathered from harvests in July of 2014, 2015 and 2016 from one location. Native plants were comparable to and often out-yielded market cultivars. As per 2015 data, some of the highest-yielding biotypes were ND 48-2, ND 1-7, ND 1-2, ND 1-5, ND 1-6, ND 1-4; comparable with market cultivars 'Success', 'Parkhill', and 'Regent'. Other qualities measured included growth habit and flower showiness.
