A New Hairy Vetch (Vicia villosa Roth) Variety, ‘Cheongpoogbora’ for Green Manure

‘Cheongpoongbora’, a winter hairy vetch variety (Vicia villosa Roth) for green manure use, was developed from the National Institute of Crop Science (NICS) in 2009. Among the genetic resourced collected in Daegu, early flowering, strongly resistant to cold, and high yield in green manure, was selected by pedigree selection method. Over the two years from 2008 to 2009, regional yield trial test was conducted with the line in four regions: Suwon, Iksan, Milyang, and Yeongdeok. As a result, in December 2009, it was named ‘Cheongpoongbora’ as a new variety. ‘Cheongpoongbora’ features medium green color leaves, medium density hair, and black seed coat. Flowering season for the variety was on April 29 on average across the nation, 11 days earlier than the check variety ‘Welta’. Also, it was more resistant to cold than ‘Welta’. The dry matter yield was average 5.20 tons per ha, 5.9% higher than ‘Welta’ (4.92 tons), the nitrogen yield was average 166 kg per ha, 6.4% higher than ‘Welta’(156 kg). ‘Cheongpoongbora’ can be cultivated in any national regions which have the daily minimum mean temperature of over-15℃ in January.
