  abstract = {{C}omponents of resistance of cassava (#{M}anihot esculenta$) to {A}frican cassava mosaic virus ({ACMV}) and their interrelationships were confirmed and quantified in a series of experiments at {A}diopodoum{\'e} ({I}vory {C}oast, {W}est {A}frica). {T}he response to virus infection and to #{B}emisia tabaci$ infestation of a large collection of cassava, including local cultivars and others derived from inter-specific #{M}. glaziovii$ hybrids was assessed. {A} consistent correlation was found between virus titre, symptom intensity, disease incidence and non-systemicity (recovery) which suggests that they are different expressions of the same genetic resistance. {B}y contrast, there was no correlation between whitefly infestation and incidence of {ACMV}, suggesting that resistance to virus and vector are determined by two distinct genetic mechanisms. {S}everal improved cultivars derived from inter-crossing cassava with #{M}. glaziovii$ as well as some local cultivars were highly resistant and combined low susceptibility, low symptom intensity, low virus content and high level of recovery. {A}lthough yield losses ranged from 10% to 30% in such resistant cultivars, the combined effect of high field resistance and high rate of recovery lead to low disease incidence and limited yield losses, even in areas of high infection pressure such as {A}diopodoum{\'e}.
