The tetraploid species Avena agadiriana that was first described in 1985 is distributed on the Atlantic coastal strip south of Casablanca in Morocco. Five accessions of this species (M55, M59, M60, M71 and M74) were compared ...
Introduced earthworms in agricultural and reclaimed land: their ecology and influences on soil properties, plant production and other soil biota

Baker, G. H.; Brown, G.; Butt, K.; Curry, J. P.; Scullion, John (Springer Netherlands, 2006-12-21)

The most conspicuous biological invasions in terrestrial ecosystems have been by exotic plants, insects and vertebrates. Less conspicuous but possibly of equal importance are invasions by soil invertebrates, which are ...

Introgression mapping for genes of abiotic stress resistance in Lolium multiflorum and Festuca pratensis

Kosmala, A.; Zwierzykowska, E.; Joks, W.; Humphreys, Michael W.; Rapacz, M.; Zwierzykowski, Z. (2003)

Festuca pratensis was used as a source of genes for drought resistance and freezing tolerance for transfer in introgression breeding programmes to high quality Lolium multiflorum cultivars. Triploid (2n = 3x = 21) hybrids ...
Introgression mapping in the grasses

King, Ian P.; King, Julie; Armstead, Ian P.; Harper, John A.; Roberts, Luned A.; Thomas, Howard; Ougham, Helen J.; Jones, R. Neil; Thomas, Ann M.; Moore, Beverley J. (2005)

Lolium perenne/Festuca pratensis hybrids and their derivatives provide an ideal system for intergeneric introgression. The work described in this paper enables the elucidation of gene organization along Lolium/Festuca ...
Introgression-mapping of genes for drought resistance transferred from Festuca arundinacea var. glaucescens into Lolium multiflorum

Humphreys, Janet; Harper, John A.; Armstead, Ian P.; Humphreys, Michael W. (2005-02-01)

Procedures for the transfer of genes for drought resistance from Festuca glaucescens (2n=4x=28) into Lolium multiflorum (2n=2x=14) are described. Following the initial hybridisation of a synthetic autotetraploid of L. ...
Introgression mapping of genes for winter hardiness and frost tolerance transferred from Festuca arundinacea into Lolium multiflorum

Kosmala, A.; Zwierzykowski, Z.; Zwierzykowska, E.; Luczak, M.; Rapacz, M.; Gasior, Dagmara; Humphreys, Michael W. (2007-07-09)

Genes for winter hardiness and frost tolerance were introgressed from Festuca arundinacea into winter-sensitive Lolium multiflorum. Two partly fertile, pentaploid (2n = 5x = 35) F1 hybrids F. arundinacea (2n = 6x = 42) x ...
Introgression of chromosomes of Festuca arundinacea var. glaucescens into Lolium multiflorum revealed by genomic in situ hybridisation (GISH)

Harper, John A.; Morgan, W. Gareth; Thomas, Huw M.; Koch, S.; King, Ian P. (2001-10)

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 ...
Introgression of crown rust (Puccinia coronata) resistance from meadow fescue (Festuca pratensis) into Italian ryegrass (Lolium multiflorum) and physical mapping of the locus

Harper, John A.; Morgan, W. G.; Thomas, Huw M.; Roderick, Hywel W. (2003-10)

Resistance was found in the meadow fescue (Festuca pratensis) to crown rust (Puccinia coronata), originating from ryegrasses (Lolium spp). A backcrossing programme successfully transferred this resistance into diploid ...
Introgression of crown rust (Puccinia coronata) resistance from meadow fescue (Festuca pratensis) into Italian ryegrass (Lolium multiflorum): genetic mapping and identification of associated molecular markers

Armstead, Ian P.; Harper, John A.; Turner, Lesley B.; Skøt, Leif; King, Ian P.; Humphreys, Mervyn O.; Morgan, W. Gareth; Thomas, Huw M.; Roderick, Hywel W. (2006-02)

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 ...
