Lolium perenne
Perennial Ryegrass is used all over the world as a valuable species for turf. Its general characteristics of excellent wear tolerance, fast germination, and quick establishment are highly valued. On the other hand, its limited drought tolerance and demand for good management (including fertilization and frequent cutting) restrict the usage of the species in certain regions and for certain purposes.
Skillful breeding has led to a wide range of varieties which differ in such characteristics as wear tolerance, winter-hardiness, color, disease resistance, sod density, growth rate, and heat and drought tolerance.
