摘要

During the past 30 years, common bean (Phaseolus vulgaris L.) production in Central America has expanded into the humid, lowlands (Gourdji et al., 2014; Aldana de León, 2010). This allows for production during non-traditional growing seasons, resulting in a greater and more stable supply of beans in the region. In the humid tropics, seed yield and seed quality of beans are threatened by web blight caused by Rhizoctonia solani Kiihn (teleomorph: Thanatephorus cucumeris Frank Donk) (Godoy de Lutz et al., 2008). High temperatures can disrupt reproductive development and reduce seed yield of heat-sensitive bean genotypes (Porch and Jahn, 2001). This study aimed to identify the response of breeding lines to web blight using a spatial model.
