Provided herein are substantially pericarp free Spinacia oleracea, or spinach, seeds. Also provided herein are methods for producing substantially pericarp free Spinacia oleracea, or spinach, seeds and Spinacia oleracea, or spinach plant capable of producing substantially pericarp free seeds. Also provided herein are Spinacia oleracea seeds wherein the seeds are substantially free of pericarp and the seeds are obtainable by crossing a female Spinacia oleracea parent plant with a male Spinacia oleracea parent plant resulting in seed production by the female Spinacia oleracea parent plant, the female Spinacia oleracea parent homozygously comprises in its genome a recessive trait substantially preventing pericarp formation on seeds produced and harvesting Spinacia oleracea seeds substantially free of pericarp.

The present invention relates to an allele designated alpha-WOLF 15 which confers resistance to at least one Peronospora farinosa f. sp. spinaciae race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif MAEIGYSVC (SEQ ID NO:13) at its N-terminus; and b) the motif KWMCLR (SEQ ID NO:14; and wherein the LRR domain of the protein has in order of increased preference at least 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID NO:10. The allele when homozygously present in a spinach plant confers complete resistance to Peronospora farinosa f. sp. spinaciae races Pfs:1, Pfs:2, Pfs:3, Pfs:4 and Pfs:5, Pfs:6, Pfs:8, Pfs:9, Pfs:11, Pfs:12, Pfs:13, Pfs:14, Pfs:15 and isolates UA1014, and confers intermediate resistance to pfs:10, and does not confer resistance to Pfs:7 and Pfs:16.

The present invention relates to an allele designated alpha-WOLF 25 which confers resistance to at least one Peronospora farinosa f. sp. spinacea race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif MAEIGYSVC at its N-terminus; and b) the motif KWMCLR; and wherein the LRR domain of the protein has in order of increased preference at least 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID NO: 5. The allele when present in a spinach plant confers complete resistance to at least Peronospora farinosa f. sp. spinacea race Pfs:8, Pfs15 and Pfs:16, and does not confer resistance to Pfs:3.

The present disclosure provides for unique spinach plants with broad-spectrum resistance to downy mildew and their progeny. Such plants may comprise an introgressed QTL associated with the broad-spectrum resistance to downy mildew. In certain aspects, compositions, including distinct polymorphic molecular markers, and methods for producing, using, identifying, selecting, and the like of plants or germplasm with resistance to downy mildew are provided.

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 present invention relates to a Spinacia oleracea seed designated 51-712 RZ, which exhibits a combination of traits slow growing, semi-savoy leaves, medium ovate mature leaves, late to very late bolting, and resistance to downy mildew (P. farinosa f. sp. spinaciae) races Pfs1 to Pfs15 and intermediate resistance to Pfs16. The present invention also relates to a Spinacia oleracea plant produced by growing the 51-712 RZ seed. The invention further relates to methods for producing the spinach cultivar, represented by spinach variety 51-712 RZ.

The present invention relates to an allele designated alpha-WOLF 8 which confers resistance to at least one Peronospora farinosa f. Sp. spinacea race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that may comprise in its amino acid sequence: a) the motif MAEIGYSVC at its N-terminus; and b) the motif KWMCLR; and wherein the LRR domain of the protein has in order of increased preference at least 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID No:12. When the allele is homozygously present in a spinach plant confers complete resistance to Peronospora farinosa f. Sp. spinacea races pfs:1, pfs:2, pfs:6, pfs:8 and pfs:15, and confers intermediate resistance to pfs:5, pfs:10 and pfs:16, and does not confer resistance to pfs:3, pfs:4, pfs:7, pfs:9, pfs:11, pfs:12, pfs:13 and pfs:14.

The invention relates to plants and plant parts, in particular spinach plants (Spinacia oleracea L.), which are resistant to Peronospora farinosa f. sp. spinaciae.
