The present invention relates to white rust resistant plants of the genus Chrysanthemum and to seeds, plant parts, plant cells and progeny thereof. The present invention further relates to means, and particularly molecular markers for identifying white rust resistant plants of the genus Chrysanthemum. Specifically, the present invention relates to plant belonging to the genus Chrysanthemum, the plants are resistant to white rust and the plants comprise in their genome at least one genomic region, or gene or allele, providing white rust resistance, the white rust resistance providing genomic region, or gene or allele, is genetically linked to a nucleic acid sequence comprised in at least one copy in the genome of the resistant plants and is represented by SEQ ID No. 2. Preferably, the present plants comprise in their genome a further genomic region, or gene or allele, providing white rust resistance, the further white rust resistance providing genomic region, or gene or allele, is genetically linked to a nucleic acid sequence comprised in at least one copy in the genome of the resistant plants and is represented by SEQ ID No. 1.
