Abstract: 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.

Abstract: The invention pertains to spinach plants comprising a gene or locus which leads to a broad spectrum resistance to Peronospora farinosa f sp. spinaciae (Pfs). The invention also relates to progeny of said spinach plants, to propagation material of said spinach plants, to a cell of said spinach plants, to seed of said spinach plants, and to harvested leaves of said spinach plants. This invention further relates to use of said spinach plants in breeding to confer resistance against Peronospora farinosa f. sp. spinaciae.
