Field Performance of Black Raspberry Cultivars in Western New York

Abstract

Nine black raspberry ( Rubus occidentalisL.) cultivars ('Allen', 'Black Hawk', 'Bristol', 'Haut', 'Huron', 'Jewel', 'Mac Black', 'Munger', and 'New Logan') were compared over four years (2006 to 2009) in a replicated field trial in western New York. Annual yields and fruit weights were recorded for each cultivar. 'Haut', 'Huron', and 'Jewel' had the highest mean cumulative yields over all four years, while ''Black Hawk' and 'Munger' had the lowest. However, based on the cultivar description of 'Black Hawk' compared to its physical characteristics and performance in this trial, it is likely this cultivar is not true to type and should be re-evaluated in the industry. Therefore this cultivar will be referred to as 'Black Hawk' ^NThereafter. 'Jewel' consistently had the greatest mean berry weight across all years, while 'Black Hawk' ^NThad the lowest berry weight. Harvest began most years in the first week of July and was complete by the end of July; each cultivar typically produced for 14 to 21 days so that harvest across all cultivars averaged 28 days. 'Haut', 'Huron', and 'Jewel' black raspberry cultivars are best suited for production in western New York and other locations with similar climates based on their higher overall yield and mean fruit weight.
