Behaviour of some hazelnut varieties in the subCarpathian area of Oltenia, Romania

In the subcarpathian area of Oltenia, hazelnut culture finds favourable conditions for developing. During 1990-1995, there was studied the behaviour of 24 varieties; 3 of them obtained in Romania, at Research Station Valcea (Valcea 22, Cozia and Romavel). The cultivars: Valcea 22, Ennis, Romavel, Du Chilly, Butler and T.G.D.L. have been emphasized because of high production (more then 2000 kg/ha) and fruiting constancy. Because of the fruit quality, there were noticed the following varieties: T.G.D.L., Romavel (for industry) and Ennis, Butler, Cozia, Valcea 22 (for table). In the climatic conditions from the area of study, the minimum temperatures are -18 to -20 degrees C during the blooming period and, for that reason, the late blooming varieties (Romavel, Ennis, Merveille de Bollwiler, Cosford) are presenting interest for the growers.
