Phatogenic vaviability of Uromyces appendiculatus in bean production areas in Northern Ecuador
Rust, caused by Uromyces appendiculatus, is one of the most important diseases of common bean that occurs in the major bean production areas of Ecuador. The disease is particularly serious as many local cultivars are highly susceptible and farmers have sequential plantings that favors the spread of the disease. The bean breeding program in Ecuador has focused on the development of rust resistance cultivars for this important production area, but in order to generate cultivars with durable resistance it is important to study the variability of rust races present in the area to know which genes could be effective throughout the region.
