Title: 'Ennis' Hazelnut
Authors: K.E. Hummer and H. Lagerstedt
Abstract:
The hazelnut (Corylus avellana L.) industry in the Pacific Northwest can be traced to one leading cultivar:
'Barcelona,' and its pollinizer 'Daviana.' In 1980 Dr.
Harry Lagerstedt, a U.S. Department of Agriculture, Agricultural Research Service Horticulturist, now retired, introduced C. avellana 'Ennis' hazelnut as a replacement for 'Barcelona'. 'Ennis' now comprises more than 15 % of the Oregon hazelnut
crop - despite the encroachment of eastern filbert blight [Anisogrammina anomala (Pk.) Muller], a fungal disease to which this cultivar is highly susceptible.
This cultivar was co-released with 'Butler'.
