Abstract: The present invention relates to identifying, selecting, or generating a barley plant or plant part having (improved) resistance (or tolerance) to Barley Yellow Dwarf Virus (BYDV) and/or insects, comprising screening for the presence or absence of one or more molecular marker co-segregating with a resistance locus comprising a resistance gene located on chromosome 3. The invention further relates to the resistance gene and polynucleotides encoding the resistance gene or capable of detecting the resistance gene, in particular molecular markers. The invention further relates to barley plants comprising the resistance gene.

Abstract: The present invention relates to non-transgenic and transgenic plants, preferably crop plants, comprising a mutation causing an alteration of the amino acid sequence in the CATD domain of the centromere histone H3 (CENH3), preferably within the loop1 or the ?2-helix of the CATD domain, which have the biological activity of a haploid inducer. Further, the present invention provides methods of generating the plants of the present invention and haploid and double haploid plants obtainable by crossing the plants of the present invention with wildtype plants as well as methods of facilitating cytoplasm exchange.

Abstract: Hybrid cereals are described which are obtained by restoring the pollen fertility for the Pampa cytoplasmic male sterility (P-CMS) and which are characterized by a reduced linkage drag. Plants are provided, in particular rye, which, as the male pollen parent, are capable of restoring the pollen fertility for the P-CMS. Furthermore, the nucleic acid molecule which carries the necessary information for restoring the P-CMS, DNA and vectors which contain such a nucleic acid molecule, corresponding host cells as well as a protein which can be encoded by the nucleic acid molecule and antibodies directed against it are also described. Furthermore, methods for the production of corresponding hybrid plants and transgenic plants are provided.
