Crown rust (Puccinia coronata) resistance (CRres), which had been introgressed from meadow fescue (Festuca pratensis) into the Italian ryegrass (Lolium multiflorum) background, was genetically mapped with amplified fragment length polymorphism (AFLP)

Lolium species (considered the ideal grasses for European agriculture) are not sufficiently robust to meet many of the environmental challenges that face extensive agriculture in less favoured areas. Fortunately, adaptations to abiotic and biotic str

An F1 hybrid (n=4x=28) between the tetraploid species Festuca arundinacea var. glaucescens (GGG′G′) and a synthetic tetraploid Lolium multiflorum (LmLmLmLm) was backcrossed to diploid L. multiflorum to produce triploid (2n=3x=21) BC1 hybrids (LmL

Chromosome structure was analysed at mitosis in root tip meristems of eight genotypes of Lolium rigidum. FISH revealed changed positions in the rDNA sites indicating extensive chromosome rearrangements; indeed no two genotypes were the same. In one g

In a L. multiflorum plant regenerated from culture, the centromere of one chromosome had mis-divided to produce two telocentric chromosomes. PRINS detected telomeric repeat sequences at the 'new' chromosome ends. The two telocentric chromosomes were

A mutant allele at the nuclear locus sid confers indefinite greenness on senescing leaves of the pasture grass Festuca pratensis. Via the bridging species Lolium multiflorum and a programme of backcrossing and selfing, the mutant allele (designated s

Lolium perenne/Lolium perenne/Festuca pratensis triploid hybrids are a potentially important source of material for determining the genetic control of agronomically and scientifically important characters and determining how genetic maps relate to ph
