Abstract  Inheritance of resistance to rust was investigated in the self progeny of the sugarcane cultivar ‘R570’ also used to build a RFLP genetic map. Resistance was evaluated through both field and controlled greenhouse trials. A clear-cut 3 (resistant) : 1 (susceptible) segregation indicative of a probable dominant resistant gene was observed. This is the first documented report of a monogenic inheritance for disease resistance in sugarcane. This gene was found linked at 10 cM with an RFLP marker revealed by probe CDSR29. Other minor factors involved in the resistance were also detected.
