Resistance in cassava manihot esculenta to diplodia manihoti



Resistance in cassava manihot esculenta to diplodia manihoti



Fitopatologia Brasileira 6(3): 359-366



Stem dry rot caused by D. manihoti Sacc., is one of the most important diseases of M. esculenta Crantz (= M utilissima Pohl) in northeastern Brazil. A study was made to identify possible sources of resistance to this disease, using 50 cassava cultivars. All cassava cultivars tested, except clone EAB 647, showed susceptibility to the pathogen. Eighteen were highly susceptible. Clone EAB 647 was considered the only source of resistance to Diplodia.
