A growth chamber experiment was carried out for ten weeks to reduce post-rooting dormancy in juneberry micropropagation. An RCBD with a split plot arrangement and three replicates were used. Plantlets subjected to 750 mg/L GA, 100 mg/L BA, and 250 mg/L GA + 100 mg/L BA recorded the greatest leaf number. Pre-rooted ‘Thiessen’ plantlets recorded the greatest biomass (fresh and dry weight) and root volume. In a second study, a cultivar evaluation was conducted in Absaraka, ND, where ten juneberry cultivars and a native biotype planted were evaluated for plant and fruit characteristics. An RCBD with four replicates was used. The high yielding cultivars for total yield were ‘Thiessen’, ‘Martin’, ‘Parkhill’, ‘Pembina’, ‘Regent’ and Native. ‘Thiessen’, ‘Martin’, and ‘Parkhill’ maintained a significant higher marketable yield. ‘Thiessen’, ‘Regent’, ‘Martin’, ‘Parkhill’ and ‘Northline’ had the largest fruits, while ‘Thiessen’ and ‘Martin’ fruit had the greatest mass.

Saskatoon serviceberry (Amelanchier alnifolia Nutt.) is an ornamental Rosaceous shrub producing delicate white flowers that yield fruit similar in appearance and nutrition to blueberry (Vaccinium spp.). Most serviceberry are propagated in Canada and, as imported stocks are often expensive, clones were accessed from 70 locations in North Dakota. Following establishment, a replicated field trial of wild biotypes of serviceberry was initiated at the North Dakota State University Horticulture Research Farm (NDSU HRF) near Absaraka, ND and at the Williston Research and Extension Center (WREC) in Williston, ND. Yield data was taken upon harvest in summers 2014-2017 at NDSU HRF and 2016 at WREC. ND 1-2, ND 1-4, ND 1-6, ND 1-7, ND 48-2 often out-yielded market genotypes. ND 15-2 was high in sugar content and gelling ability, ideal for processing. Through continued selection, North Dakota growers may have quality serviceberry from a local source.
