Department of Plant Agriculture, University of Guelph. The nine parents of
Jay were selected for general vigour, late maturity, plant height at headin
g, and aftermath vigour. It is similar in herbage yield and plant height bu
t slightly later maturing than the cultivar Kay. Jay is suited for situatio
ns where a late-maturing orchardgrass is desired.
