Project objectives

Project summary and status as of 1 January 2007

The first Scandinavian variety testing project under realistic green conditions was carried out from 2003 to 2006 on USGA-specification greens at the Norwegian research stations Landvik (58°N, 12 m a.s.l.) and Apelsvoll (61°N, 250 m a.s.l.). The two sites were considered to be representative for the southern/coastal and the northern/continental zones of Scandinavia. The trials were managed as ordinary putting greens including mowing three times per week to 4.5-5.0 mm for Festuca and 3 mm for Agrostis and Poa. Forty-three varieties belonging to six different species/subspecies were tested.

On average for varieties within each species, Agrostis canina had the highest visual merit scores at both experimental sites. Poa annua ‘True Putt’ was at the bottom of the list and should not be seeded on putting greens in any part of Scandinavia. Within the other species, recommended varieties have been ranked as follows:
