Understanding the Genetic Basis of Flowering and Fertility in the Ryegrasses (Lolium spp.)
Ryegrasses and fescues of the Lolium/Festuca complex form the basis of many temperate grassland agricultural and turf systems and the ability to manipulate flowering and fertility within these grasses is of considerable importance. Genetic studies can identify multiple quantitative trait loci affecting these traits which can be used in the development of marker-assisted selection protocols for combining favourable alleles. By applying a knowledge of plant comparative genetics and genomics, it is possible to increase the information content of these studies by ‘cross-referencing’ between the Lolium/Festuca grasses and other crop and model species (e.g. rice, Triticeae cereals, Arabidopsis). Syntenic genomic regions, new genetic markers and candidate genes can, thus, be identified.
