| consistent detection of qtls for crown rust resistance in italian ryegrass (lolium multiflorum lam.) across environments and phenotyping methods. | crown rust, caused by puccinia coronata f. sp. lolii, is one of the most important diseases of temperate forage grasses, such as ryegrasses (lolium spp.), affecting yield and nutritional quality. therefore, resistance to crown rust is a major goal in ryegrass breeding programmes. in a two-way pseudo-testcross population consisting of 306 lolium multiflorum individuals, multisite field evaluations as well as alternative methods based on artificial inoculation with natural inoculate in controlled ... | 2007 | 17426957 |
| development and characterization of est-ssr markers for the crown rust pathogen of ryegrass (puccinia coronata f.sp. lolii). | the causative organism of crown rust in ryegrasses (puccinia coronata f.sp. lolii) is an obligate biotroph that causes significant economic losses within the temperate grazing industries of dairy, meat, and wool production. this study reports on the development, transferability, and utility of gene-associated simple sequence repeat (ssr) molecular markers for crown rust. analysis of 1,100 expressed sequence tag (est) sequences from a urediniospore-derived cdna library detected 55 ssr loci. the m ... | 2006 | 16936837 |
| four qtls determine crown rust (puccinia coronata f. sp. lolii) resistance in a perennial ryegrass (lolium perenne) population. | crown rust resistance is an important selection criterion in ryegrass breeding. the disease, caused by the biotrophic fungus puccinia coronata, causes yield losses and reduced quality. in this study, we used linkage mapping and qtl analysis to unravel the genomic organization of crown rust resistance in a lolium perenne population. the progeny of a pair cross between a susceptible and a resistant plant were analysed for crown rust resistance. a linkage map, consisting of 227 loci (aflp, ssr, rfl ... | 2005 | 16118663 |
