AC Oxley II cicer milkvetch

Abstract

AC Oxley II cicer milkvetch (Astragalus cicer L.) was developed by the Agriculture and Agri-Food Canada Research Centre, Lethbridge, Alberta. This synthetic cultivar developed for improved seedling vigour and tested as LRC95-93-1 in Western Forage Tests established in 1996 outyielded Oxley, the check cultivar, by 19%. In western Canada, under dryland conditions AC Oxley II produced 23% more dry matter than the Oxley check, while under irrigation the yield advantage was 11%. AC Oxley II is well suited for pasture and hay production in western Canada. The new cultivar produced about 10 percent more seed than Oxley at Lethbridge under irrigated conditions.
