In 2009, barley plants from the collection of genetic resources were grown under the same conditions as the current standard varieties in one testing site in the forage production area. Most of the old varieties achieved full ripeness even by 9 days earlier than the standard varieties. The standard varieties and also a number of older ones had 800 and more productive stems per square m and about by 1.5 t/ha higher yield of grain. The standard varieties and breeding lines were on average by 30 cm lower than the other varieties studied. Weight of one thousand grain varied in the range from 28.3 g to 45.8 g. Standard varieties, breeding lines and some landraces and old varieties were resistant to Blumeria graminis. Infestation with Puccinia hordei was not recorded in most of the studied varieties. Most varieties were medium or less resistant to Pyrenophora teres. In two thirds of the varieties infestation with Rhynchosporium secalis was not recorded.
