Ennis — A Large Filbert

Abstract

Ennis is a round nut that is larger and more productive than the standard main crop cultivar Barcelona. The latter has been the major cultivar planted in the Pacific Northwest since the turn of the century and now represents about 85% of the filberts produced. Barcelona has served the industry well, but it has several faults that are absent in Ennis. Barcelona may produce as high as 20% blanks (empty shells), is highly susceptible to "Brown Stain," a physiological disorder, is strongly biennial bearing, and has certain unattractive shell and kernel characteristics. Ennis is being planted as rapidly as trees become available from nurserymen and should prove to be a great improvement over Barcelona.
