The invention relates to plants and plant parts, in particular spinach plants (.), which are resistant tof. sp.. The invention also relates to seeds capable of producingf. sp.resistant plants. The invention further relates to methods for obtaining said plants with altered genotypes and seeds thereof, which are resistant tof sp.

Non R-gene mediated resistance

The invention relates to plants and plant parts, in particular spinach plants (L.), which are resistant tof. sp.. The invention also relates to seeds capable of producingf. sp.resistant plants. The invention further relates to methods for obtaining said plants with altered genotypes and seeds thereof, which are resistant tof. sp.

The present invention relates to a spinach plant which may comprise a single dominant gene which confers resistance tof. sp.races Pfs1, Pfs2, Pfs3, Pfs4, Pfs5, Pfs6, Pfs9, Pfs11, Pfs12, Pfs13 and UA4410, and to isolate E1314-283, wherein the gene is obtainable by introgression from a plant grown from seeds of which a representative sample was deposited with the NCIMB under NCIMB accession numbers 41857, 41976, 41977, 41978, 41980, 41981, 41984, 42116. The invention further relates to progeny of the plant, to propagation material therefore, such as seed, and to food products which may comprise the spinach leaves.

[object Object]

The present invention relates to a spinach plant which may comprise a single dominant gene which confers resistance tof. sp.races Pfs1, Pfs2, Pfs3, Pfs4, Pfs5, Pfs6, Pfs9, Pfs11, Pfs12, Pfs13 and UA4410, wherein the gene is obtainable by introgression from a plant grown from seeds of which a representative sample was deposited with the NCIMB under NCIMB accession number 41857. The invention further relates to progeny of the plant, to propagation material therefore, such as seed, and to food products which may comprise the spinach leaves.

The present invention relates to a spinach plant () which may comprise a genetic determinant that leads to the plant having a red coloration of the leaves, which genetic determinant may be obtainable from a spinach plant comprising said genetic determinant, representative seed of which was deposited with the NCIMB under accession numbers NCIMB 41954, NCIMB 41955 and NCIMB 41956.

Red spinach plant

The present invention relates to the field of plant breeding and more particular to the development of a spinach plant that expresses a new resistance pattern against downy mildew (f. sp. Spinaciae) strains Pf1-Pf12 and isolate PfsUA441), methods and compositions relating to plants, progeny, seeds and derivatives thereof and plants, progeny, seeds and derivatives thereof having all the morphological, physiological and/or genetic characteristics thereof.
