In 2006 and 2007 old varieties were grown in one locality in the forage production area under the same conditions as the current varieties. Most old varieties headed even 5 days earlier than the current varieties and the old varieties also achieved full maturity earlier. The current varieties had a higher number of fertile tillers/per m2 and approximately by 2 t/ha higher grain yield. On average, old varieties were higher by 25-30 cm. The current varieties showed higher resistance to lodging, significantly higher resistance to powdery mildew and partly also to brown rust. In net blotch, there were no significant differences between the old and current varieties. Resistance to scald was in the old and current varieties approximately the same. TGW in the new varieties was slightly higher than in the old ones.In 2006 and 2007 old varieties were grown in one locality in the forage production area under the same conditions as the current varieties.
