Within the framework of cooperation programme between USA and Baltic states 18 varieties of USA and 12 of Canadian origin were tested at the Jogeva Plant Breeding Institute in 1993...1998, aiming at investigation of their winter survival, yield capacity and forage quality. The trial was established in five replications, sown in wide-apart (60 cm) rows. Forage was cut once in seeding year and three times in a year thereafter. To investigate the forage quality, crude protein content was assessed both in the entire herbage and crop fractions. The winters during the testing period were favourable for alfalfa, except the winters 1993/94 and 1998/99 when the stands of North American alfalfa varieties were injured, in the latter case even in an extent which resulted in termination of the trial one year earlier than planned
