Hybrid spinaches ‘E03D.1042’, ‘E03D.1047’, and ‘E03D.1051’ are described. ‘E03D.1042’, The invention relates to the seeds of hybrid spinaches ‘E03D.1042’, ‘E03D.1047’, and ‘E03D.1051’, to the plants of hybrid spinaches ‘E03D.1042’, ‘E03D.1047’, and ‘E03D.1051’, to methods for producing hybrid plants, and to methods for producing other spinach lines, cultivars or hybrids derived from the hybrid spinaches ‘E03D.1042’, ‘E03D.1047’, and ‘E03D.1051’.

The present disclosure relates to the field of plant breeding and, more specifically, to the development of white rust (Albugo occidentalis) resistant and downy mildew (Peronospora farinosa f. sp. spinaceae) resistant spinach plants having elite agronomic traits. The resistance to white rust is conferred by one or more alleles that co-segregate with at least one molecular marker selected from the group of SEQ ID No. 1-10. The resistance to downy mildew is conferred by an allele that co-segregates with at least one molecular marker selected from the group of SEQ ID No. 11-13. The disclosure relates further to the use of the molecular markers.

Provided herein are spinach plants resistant to Peronospora farinosa and Stemphylium vesicarium, and spinach plants additionally resistant to Cucumber Mosaic Virus (CMV). Also provided herein are genomic fragments providing the present resistances and use thereof for identifying spinach resistant to Peronospora farinosa and Stemphylium vesicarium, and spinach plants additionally resistant to Cucumber Mosaic Virus (CMV). Provided herein are a spinach plant resistant to Peronospora farinosa and Stemphylium vesicarium: including a genomic fragment of Spinacia tetrandra located on chromosome 4 between positions 8255074 and 8620598 of the spinach reference genome, the genomic fragment of Spinacia tetrandra lacking a lethal factor and providing Peronospora farinosa resistance and including a genomic fragment located on chromosome 3 and between positions 1177586 and 1271037 of the spinach reference genome providing Stemphylium vesicarium resistance.

The invention relates to a cultivated spinach plant having a new resistance against at least Peronospora farinosa races 8, 9, 11, 13 and 16, seed, cell cultures and progeny of said plant, use of the plant with the resistance, and methods for generating and identifying such a plant.

The object of the present invention is to provide a spinach line with the novel feature of solid petioles at harvest time. As a result of developing many progeny lines having petioles in which the hollow portion is relatively small over many years, a spinach line having solid petioles at harvest time was constructed.

The invention relates to a cultivated spinach plant having a new resistance against at least Peronospora farinosa races 8 and 10 to 16, seed, cell cultures and progeny of said plant, use of the plant with the resistance, and methods for generating and identifying such a plant.

The invention provides seeds and plants of spinach hybrid SVVB0421. The invention thus relates to the plants, seeds, plant parts, and tissue cultures of spinach hybrid SVVB0421 and to methods for producing a spinach plant produced by crossing such plants with themselves or with another plant, such as a spinach plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to plants, seeds, plant parts, and tissue cultures of spinach hybrid SVVB0421 comprising introduced beneficial or desirable traits.

The invention provides a new and distinct hybrid variety of Spinach, NUN 06258 SPS as well as seeds and plants and leaves thereof.

The present invention relates to a method for modifying the resistance profile of a spinach plant to Peronospora farinosa f sp. spinaciae, comprising introducing a WOLF allele or a resistance-conferring part thereof into the genome of said spinach plant, or modifying an endogenous WOLF allele in the genome of said spinach plant. A WOLF allele encodes a CC-NBS-LRR protein that comprises in its amino acid sequence: the motif MAEIGYSVC at its N-terminus, and the motif KWMCLR for alpha-type WOLF proteins or HVGCVVDR for beta-type WOLF proteins. The invention relates to the WOLF alleles referred to in Table 3. The invention further provides a method for selecting a spinach plant comprising a novel WOLF gene that confers resistance to Peronospora farinosa f sp. spinaciae in a spinach plant and a method for identifying a WOLF allele that confers resistance to one or more pathogenic races of Peronospora farinosa f. sp. spinaciae in a spinach plant and to primers for use in these methods.

The invention provides a new and distinct hybrid variety of Spinach, NUN 06303 SPS as well as seeds and plants and leaves thereof.
