Abstract

The present invention relates to powdery mildew, and especially powdery mildew caused by the plant pathogen Erysiphe heraclei, resistant carrot plants or Daucus carota plants, wherein the powdery mildew resistance is provided by one or two dominant powdery mildew resistance genes. The present invention further relates to molecular markers genetically linked to the present powdery mildew, and especially powdery mildew caused by the plant pathogen Erysiphe heraclei, resistance providing genes and the use thereof for identifying carrots plants, or Daucus carota plants, being resistant to powderymildew, and especially powdery mildew caused by the plant pathogen Erysiphe heraclei. The present invention also relates to seeds, plant parts, pollen, egg cells, callus, suspension culture, somatic embryos and edible plant parts of the present plants.

Description

technical field [0001] The present invention relates to powdery mildew, and in particular powdery mildew caused by the phytopathogen Erysiphe heraclei, resistant carrot plants or wild carrot (Daucus carota) plants, wherein powdery mildew resistance is dominated by one or two dominant Powdery mildew resistance gene provided. The invention also relates to molecular markers genetically linked to the powdery mildew of the invention, and in particular to powdery mildew caused by the phytopathogen Erysiphe heraclei, resistance-providing genes and their use in identifying resistant Use of carrot plants or Daucus carota plants affected by powdery mildew, and in particular powdery mildew caused by the phytopathogen Erysiphe heraclei. The invention also relates to seeds, plant parts and in particular edible plant parts of the plants according to the invention. Background technique [0002] Carrot or wild carrot is a cultivated plant from the family Umbelliferae (or Apiaceae) which i...
