The state of Mato Grosso, located in central region of Brazil (Fig. 10.1), is considered as a center of origin and domestication of cassava, as well as a center of diversity (Carrasco et al., 2016; Isendahl, 2011; Nassar, 2000; Olsen, 2004). Although Mato Grosso occupies a prominent position regarding the agricultural production of commodities (soybeans, corn, cotton, and meat), it has expressive family agriculture, which plays a fundamental role in rural development, and generates a large part of the production of the State?s daily food consumption, in addition to generating employment (Abreu et al., 2021). In Mato Grosso, 69% of rural properties are predominantly family economies and, of these, 90% cultiva grow cassava, along with other crops (Embrapa - Empresa Brasileira de Pesquisa Agropecua´ria, 2014). Studies on the use and conservation of cassava grown by family farmers have been carried out in Mato Grosso for approximately 30 years (Amorozo, 1996, 2000, 2013; Carniello, 2007; Carrasco, 2012; Cultrera, 2008; Marchetti, 2012; Oler, 2012, 2017; Tiago, 2016), especially in the southern and northern central region of the state. The central-southern portion comprises an area of older colonization and is home to numerous traditional communities that cultivate cassava, mainly for subsistence (Marchetti et al., 2013). Thus, this region is an important center for the maintenance of local varieties, since there is a wide diversity of cassava varieties cultivated among the farmers of this region. The economy in these communities is devoted to the production of fresh food and trade of surplus, such as cassava, rice, bananas, or by-products, such as Brazilian cassava flour (Castro, 2009).  aCassava  aEthnobotany  aPathogen characterization  aPlant characteristics  aVarieties  aCaracterísticas Agronômicas  aEtnobôtanica  aGenética  aGenética Molecular  aMandioca  aManihot Esculenta  aVariedade  aMorphological1 aTIAGO, A.
