Description
Mathieu Tiret and colleagues report a 2026 study of flea beetle resistance in cabbage kin. The cabbage stem flea beetle grows as a threat to winter Brassica crops in Europe, oil and vegetable plants of the cabbage family. Genetic basis of resistance was poorly understood. The team ran a genome wide association study, which scans the full genome for trait links. They joined pooled gene reads with a large feeding test on one hundred thirteen Brassica oleracea types.
Resistance showed moderate heritability with a mostly polygenic base, meaning many small gene effects. Types split sharply: cabbage head types were mostly susceptible, while cauliflower types and wild groups resisted far more. One major effect zone on chromosome C01 stood out despite the small effect back cloth. Resistance alleles piled up in wild groups, while susceptible alleles ruled in head cabbage. Wild kin hold the resistance stock for breeding.
