Plant traits affecting thrips resistance in cabbage

Summary in the original language of the document

The development of thrips populations and thrips damage in 15 cabbage varieties was monitored in two years of field experiments in the Netherlands.. A number of morphological and physiological plant traits were also measured. The most important factors leading to a low level of thrips damage were late development of a compact head, a low Brix value and a high amount of leaf wax. Two open-pollinated cabbage varieties with low and high susceptibility to thrips damage were crossed in both reciprocal combinations. The resulting F1 populations were intermediate for susceptibility to thrips damage.
