- Abstract
Th e paper deals with growth and prosperity of 25 provenances of grand fi r from Washington, Oregon, Idaho and Montana (USA), and from Vancouver (British Columbia, Canada) tested in the international provenance research trial No. 212 – Drahenice (Czech Republic; N49° 31‘ 10‘‘, E13° 57‘ 20‘‘, 570 m a.s.l., acidic beech site). Biometric measurements took place at the age of 41 years; qualitative features were visually assessed according to the IUFRO methodology. Th e best overall assessment of both production and quality shows provenance 12041 – Oyster Bay (BC). Other provenances with high growing stocks, i.e. 12005 – Bear Mountain (WA), 12038 – Clearwater (ID), 12043 – Sproat Lake (BC) and 12044 – Kaye Road (BC) showed some qualitative shortcomings (lower vitality, worse stem shape or thicker branches). Th e worst both in production and quality were provenances 12020 – Crescent Creek (OR) and 12011 – Clear Lake (WA). Th e results confi rm the suitability of the current setting of the rules for the transfer of reproductive material from North America to the Czech Republic.
