| Abstract/Contents: | "Ryegrass (Lolium spp.) are cool-season grasses used for both turf and pasture. Knowledge of genes controlling morphological differences between annual and perennial types would help in understanding relationship among species and assist breeders in turfgrass improvement. Quantitative trait loci (QTLs) for a number of plant appearance traits of ryegrass were identified using a turf-type perennial (Lolium perenne L.) x annual (or Italian) (Lolium multiflorum Lam.) hybrid mapping population. The objective of this ongoing research was to identify candidate gene regions associated with morphological differences between perennial ryegrass and annual ryegrass. The population was studied in the field at three locations for two years. QTLs were detected for plant height, the size of various plant structures, tiller number, growth habit, plant color and vigor. A number of traits were significantly correlated with each other, and coincident QTLs were identified. The largest cluster of QTLs was located on linkage group 4 in a region syntenic with the portion of chromosome 5 in what bearing the Vrn-1 gene. The Vrn-1 gene is one of the vernalization genes related to plant response to temperature and photoperiod. These are the environmental stimuli for grass growth type. Mapping of these QTLs provides a base for marker-assisted selection and identifies regions of the genome of interest for future gene discovery efforts." |
