Abstract:
Perennial ryegrass (Lolium perenne L.) is a member of the Poaceae family, is native
to Europe, the Near East and North Africa and is grown in all the temperate climate
areas of the world as a forage and turf grass. Due to its persistence, palatability and
nutritive value for ruminants, it is a principal component of pastures, and the most
important forage species in Ireland. The primary aim of this thesis was to characterise
the level of diversity in a large genetic resource collection of L. perenne germplasm
held at Teagasc, Oak Park. Molecular markers, both chloroplast and nuclear SSRs,
biochemical characters (water soluble carbohydrate, crude protein, and dry matter),
and morphological characters (vegetative and flowering) were used to characterise
this diversity, as well as population differentiation, and geographic patterns. Levels of
diversity in all systems were found to be high in this collection.
