**12. Summary and prospects of clubroot disease control**

Crop plants are always challenged by various biotic and abiotic stresses. In agriculture cropping system, plant protection is being delivered using different approaches such as chemical control, various agronomic practices, biological control, integrated pest manage‐ ment (IPM), and cultivation of resistance cultivars. Among these approaches, resistance cultivars are the most economical, environmentally sustainable solution to control differ‐ ent diseases including clubroot in Brassica species. Previous studies suggested that the inheritance of clubroot resistance is either qualitative or quantitative in Brassica species. Recently mapped clubroot resistance genetic loci and closely linked molecular marker to these loci can be used for marker-assisted selection in clubroot resistance breeding of Brassica species. Extensive use of recently available resistance sources can be combined with molecular tools and new technologies such as gene/QTL mapping, fine mapping, gene cloning, comparative genomics and analysis of transcriptomic profiles through nextgeneration sequencing, which could enhance our understanding of clubroot resistance mechanism. Novel information can help controlling clubroot disease in an effective way, so yield losses would be reduced and the quality of Brassica crop product would be improved.
