Seed characteristics are not distinctive enough for reliable identification of Festuca rubra L. cultivars; therefore, research was conducted to identify seedling characteristics useful for cultivar purity testing. Starting 2 weeks after seeds were planted, seedlings were sprayed three times, at 3‐day intervals, with 700 μ l/liter of ethephon (2‐chloroethyl‐phosphonic acid) until the foliage was completely wet. This resulted in development of two distinctly different types of plants. The first had long‐narrow‐leaf blades and the second had short‐wide leaf blades. All seedlings of the Chewing fescue cultivars ‘Cascade’, ‘Highlight’, and ‘Jamestown’ were of the long‐narrow leaf type. In contrast, all seedlings of ‘Rainier’ and 98% of the seedlnigs of ‘Ruby’ red fescue were of the short‐wide leaf type. ‘Arctared’, ‘Illahee’, and ‘Pennlawn’ red fescue developed 74, 36, and 39% short‐wide leaf plants respectively. Even though this technique distinguishes only two types of plants, it was useful in determining accuracy of labeling of Festuca rubra L. seed samples.
