![]() Infected bolls have round, as opposed to angular, lesions that initially may appear water-soaked, and then become sunken and dark brown to black. Leaf petioles and stems may also become infected (cotton black leg), which can lead to premature defoliation of the plant. Foliar disease is characterized by angular leaf spot with a red to brown border. malvacearum infects plant tissues and organs of cotton during all stages of development beginning with the seedling stage. Today, this disease occurs in all cotton-growing areas throughout the world and was shown to be a serious limiting factor of fiber production in the US, India and in Africa. The first detailed description of CBB was made in the US. Despite its strong contribution to youth employment and rural people’s incomes, the cotton farming faces many parasitic constraints including cotton bacterial blight (CBB) disease caused by Xanthomonas citri pv. In Africa, Mali is the largest producer, followed by Burkina Faso with a production of 613,000 tons for the season 2017-2018. However, almost all the commercial cotton grown in the world comes from varieties of the native species Gossypium hirsutum and G. It is native to tropical and subtropical regions around the world, including America, India and Africa. Gossypium sp., belonging to Malvaceae family, represents is the most widely grown fiber plant in the world. pv malvacearum, Cotton Bacterial Blight, Burkina Faso Keywords: Gossypium ssp, Xanthomonas citri. For better management of cotton blight, the knowledge of the phenotypic diversity of pathogen strains, their spatial and temporal distribution is a prerequisite to guide the use of resistance gene in breeding program and their deployment in cotton growing areas in Burkina Faso. No source of resistance was detected against race 20 of X. ![]() However, with race 18 strain, some cultivars conserve bacteria into stem and leave that remain asymptomatic 35 days after inoculation. malvacearum race 18 from leaves, stem and boll inoculation. Our results show that two conventional and commercialized varieties, FK64 and FK37, and traditional accessions belonging to the species hirsutism, barbadense and arborerum harbor resistance against X. malvacearum in artificial inoculation conditions within a collection of local cotton cultivars. The main objective of the present study was to identify resistance sources against races 18 and 20 of Xanthomonas citri pv. In several countries, control has been achieved through the use of resistant cotton genotypes associated with agricultural methods limiting disease spread. pv malvacearum, is a severe disease occurring in all cotton-growing areas.
