  abstract = {{A} monogenic recessive resistance to {R}ice yellow mottle virus ({RYMV}) found in the {O}ryza sativa indica cultivar {G}igante and in a few {O}ryza glaberrima cultivars provided a higher level of resistance than either a polygenic partial resistance found in some japonica cultivars which delayed symptom expression or transgenic resistances which were partial and temporary. {T}his high resistance was overcome by several isolates, but the percentage of such virulent isolates in the fields was low. {T}here was no relationship between the virulence of an isolate towards the high resistance and its aggressiveness in other cultivars. {I}solates with either of the two components of pathogenicity - virulence and aggressiveness - were found in each strain and in all regions of {A}frica, in both wild and cultivated grass species. {T}here was no loss of fitness of resistance-breaking ({RB}) isolates as they were not counter-selected, impaired or outperformed after serial passages in susceptible cultivars, even in mixture with avirulent quasi-isogenic wild type isolates. {R}esistance breaking was highly dependent on the amount of virus inoculated and on the mode of transmission. {I}mplications of these results for the durability of the resistances to {RYMV} and for the development of integrated disease management strategies are discussed.},
