Abstract

Hairy vetch (vicia villosa) is suitable winter crop for cold drylands because of its specific characteristics especially for its cold tolerance. Gholshan cultivar has been derived and released through individual selection within local hairy vetch landraces. Initially, 105 single plants collected from vetch landraces in Kurdistan, Zanjan and east Azarbaijan provinces were evaluated and cold tolerant genotypes in autumn planting were selected for further investigations. After elementary and advanced trials in Maragheh and Qorveh, 12 superior lines were identified and then were studied in terms of adaptability and yield stability at Maragheh, Qorveh and Oroumieh research stations. The results showed that Vv-Zanjan Sel 4 had the lowest mean rank and stanrdard deviation over all environments and with 3057 kgha-1 dry forage yield was the most stable cultivar over studied environments. Studies in the Hashtrood and Charoymagh on-farm trials showed that Vv-Zanjan Sel 4 had 20% higher dry forage compared to the control cultivar. The plant height of new cultivar was 10 cm higher than gholsefid control. There were no symptoms of fusarium wilt and/or ascochita blight on this cultivar during the elementary and advanced field trials. It was concluded that Vv-Zanjan sel 4 is a suitable winter crop for cold and semi-cold drylands because of its higher forage yield and stability and therefore it was released as cv. Gholshan.
