Protocol revised before 2017 sowing, based on meetings in the Scanturf-network in Copenhagen, Denmark, September 26 2011 and Kristiansand, Norway, June 26 2012.

REFERENCE VARIETIES

Candidate varieties will be tested against two reference varieties of the same species or subspecies according to table 1.

Table 1. Reference varieties to be used in 20171)

1) When taken out of the marked, reference varieties might be replaced with newer and more suitable varieties. However, in order to maintain continuity, only one of two reference varieties within each species can be replaced at a time.

VARIETIES TESTED FOR SHORT-CUT LAWN, MOWING HEIGHT 15-20 MM.

Management in the seeding year

All candidate and reference varieties are established in field trials according to a randomised block design with 3 replications and a plot size of 1.5 to 3 m2.
