We describe an association mapping approach using natural populations of perennial ryegrass (Lolium perenne L.) to identify molecular markers associated with heading date, an important trait affecting seasonal production, ...

Publication of the rice genome sequence has allowed an in-depth analysis of genome organization in a model monocot plant species. This has provided a powerful tool for genome analysis in large-genome unsequenced agriculturally ...

Linkage maps of perennial ryegrass were constructed from F2 and BC1-type populations using, predominantly, restriction fragment length polymorphism data based on heterologous probes used in mapping other grass species. The ...

A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line (2n 2x 14). The chromatin of F. pratensis and L. perenne can be distinguished ...

Background and Aims: Perennial ryegrass (Lolium perenne) is one of the key forage and amenity grasses throughout the world. In the UK it accounts for 70 % of all agricultural land use with an estimated farm gate value of ...

A molecular-marker linkage map has been constructed for perennial ryegrass (Lolium perenne L.) using a one-way pseudo-testcross population based on the mating of a multiple heterozygous individual with a doubled haploid ...

Molecular marker analysis and genomic in situ hybridisation (GISH) were used to examine the process of chromosome segment introgression in BC2 diploid hybrids (2n=2x=14) between Lolium perenne and Festuca pratensis. Two ...

The two-locus gametophytic incompatibility system in perennial ryegrass (Lolium perenne L.) is not always fully effective: obligate selfing of plants sieves self-compatible pollen mutants, and self-fertility becomes fixed ...
