Carrot belongs to the top ten of vegetable crops worldwide and was cultivated in 2020 in Germany on 13,800 ha. 20% of these accounted for organic farming. The total yield increased by 18,4% in comparison to 2019. But the yield per hectare varies significantly from year to year. Besides abiotic factors infestation with pathogens and pests, as for instance nematodes, are responsible for such variations.Aim of the project is the identification of resistance genes against the Northern root-knot nematode Meloidogyne hapla and the Carrot cyst nematode Heterodera carotae in carrot wild species and the transfer to the cultivated carrot Daucus carota ssp. sativus. Besides resistant carrot lines also molecular markers should be provided to the breeders as selection tool for resistance. The project includes a backcross program for development of introgression lines, genetic studies, genotyping and QTL analyses and the clarification of the resistance mechanisms for the development of ecological control stategies.
