Jh. Daugrois et al., A PUTATIVE MAJOR GENE FOR RUST RESISTANCE LINKED WITH A RFLP MARKER IN SUGARCANE CULTIVAR R570, Theoretical and Applied Genetics, 92(8), 1996, pp. 1059-1064
Inheritance of resistance to rust was investigated in the self progeny
of the sugarcane cultivar 'R570' also used to build a RFLP genetic ma
p. Resistance was evaluated through both field and controlled greenhou
se trials. A clear-cut 3 (resistant): 1 (susceptible) segregation indi
cative of a probable dominant resistant gene was observed. This is the
first documented report of a monogenic inheritance for disease resist
ance in sugarcane. This gene was found linked at 10 cM with an RFLP ma
rker revealed by probe CDSR29. Other minor factors involved in the res
istance were also detected.
