AAC Glenview sainfoin, tested as LRC 4342, was developed by the Agriculture and Agri-Food Canada (AAFC) Lethbridge Research and Development Centre, Lethbridge, Alberta. This cultivar was derived from parental clones selected for improved forage yield in mixed stands with alfalfa under grazing and regrowth after grazing. When grown under irrigated and rainfed conditions in western Canada, Glenview out yielded Nova (check) by 21% in pure stands over 37 location–years and 19% in mixed stands with alfalfa over 17 location–years. This cultivar flowers and matures about 8 d earlier than Nova and has slightly larger seed than Nova (24.7 g 1000 seeds^-1 vs 20 g 1000 seeds^-1). It can be grown for hay and pasture in pure stands but Glenview is well suited for mixed sainfoin–alfalfa stands. Breeder seed for the cultivar will be produced by AAFC and the multiplication and distribution rights were awarded to Monarch Feeders Ltd., Monarch, AB, Canada.
