View article: Identifying variants associated with dwarfism via long read sequencing of the<i>Ddw1</i>locus in winter rye
Identifying variants associated with dwarfism via long read sequencing of the<i>Ddw1</i>locus in winter rye Open
Dwarfism or semi-dwarfism is an established characteristic in the European cereal market, for example semi-dwarf barley and wheat are commonplace. However, dwarf winter rye is still atypical commercially and fundamental research into the u…

Studying Stem Rust and Leaf Rust Resistances of Self-Fertile Rye Breeding Populations Open
Stem rust (SR) and leaf rust (LR) are currently the two most important rust diseases of cultivated rye in Central Europe and resistant cultivars promise to prevent yield losses caused by those pathogens. To secure long-lasting resistance, …

Maternal differences for the reaction to ergot in unfertilized hybrid rye (Secale cereale) Open
Claviceps purpurea causing ergot maintains to be a problem in commercial cytoplasmic male sterile (CMS)-based hybrid rye growing. The fungal spores compete with pollen during flowering and ergot incidence is reduced in highly pollen-sheddi…

Appreciable genetic correlation between inbred lines and testcrosses facilitates breeding for resistance to Fusarium head blight in hybrid rye (<span><i>Secale cereale</i></span>) Open
Hybrid breeding is based on selection of inbred lines in early generations. A sufficient genetic correlation between inbred lines and testcrosses is, however, the prerequisite for a higher selection gain in the hybrids. Therefore, we inves…

Ergot Alkaloid Contents in Hybrid Rye are Reduced by Breeding Open
Contamination by ergot caused by the phytopathogenic fungus Claviceps purpurea is a constant threat to the whole rye value chain. Ergot alkaloids (EA) produced within the fungal sclerotia are toxic for humans and animals and are subjected …

Genetic variation of seed phosphorus concentration in winter oilseed rape and development of a NIRS calibration Open
Phytic acid is the major organic phosphorus storage compound in rapeseed. Following oil extraction, the defatted meal is used in feed mixtures for livestock. However, monogastric pigs and chickens can only poorly metabolize phytate. Hence,…

Screening and genetic studies on resistance to Soil-born Cereal Mosaic Virus (SBWMV) in rye Open
Due to several reasons soil-borne viruses such as the furoviruses, i. e., cereal mosaic virus (SBCMV) and wheat mosaic virus (SBWMV) as well as the bymovirus wheat spindle streak mosaic virus (WSSMV) gained importance in cereal breeding in…

Covariation of Ergot Severity and Alkaloid Content Measured by HPLC and One ELISA Method in Inoculated Winter Rye across Three Isolates and Three European Countries Open
Ergot caused by Claviceps purpurea is a problem for food and feed security in rye due to the occurrence of toxic ergot alkaloids (EAs). For grain elevators and breeders, a quick, easy-to-handle, and cheap screening assay would have a high …

Mapping Stem Rust (Puccinia graminis f. sp. secalis) Resistance in Self-Fertile Winter Rye Populations Open
Rye stem rust caused by Puccinia graminis f. sp. secalis can be found in all European rye growing regions. When the summers are warm and dry, the disease can cause severe yield losses over large areas. To date only little research was done…
