Most forage crops growing under field conditions are often being exposed to various environmental stresses such as drought, freezing, high temperature, waterlogging and climate change. A combination of grass breeding approaches will likely be needed to improve significantly the environmental stresses tolerance of forage crops in the field. Attempts have been taken by grass breeders to develop tolerant varieties of different crops for environmental stress. A new tall fescue variety (Festuca arundinacea Schreb.) named ‘Purumi’ was developed by the National Institute of Animal Science, Rural Development Administration from 1999 to 2007. For synthetic seed production of this new variety, 5 superior clones, EFa9108, EFa0010, EFa0020, EFa0108, and EFa0202 were selected and polycrossed. The agronomic growth characteristics and forage production capability of the seeds were studied at Cheonan from 2004 to 2005, and regional trials were conducted in Cheonan, Pyungchang, Jeju, and Jinju from 2008 to 2010. ‘Purumi’ showed enhanced winter hardiness, disease resistance, and regrowth ability as compared to ‘Fawn’. The dry matter yield of ‘Purumi’ was about 5.6% higher as 16,821kg/ha than that of ‘Fawn’. However, the nutritive value of both varieties was similar. When this new variety of tall fescue, Purumi, has been developed and distributed with its most remarkable adaptability for Korean climates and superior value as a livestock feed, it is expected to play an important role for a new restoration of the pasture industry in Korea.
