Methods for screening of resistant cultivars by fungal inoculation techniques and field evaluation unde r natural infection condition have been established
(Muim ba,1982; Fokunan g, 1995), but these methods have their
limitations.
In vivo evaluation of cassava cultivars for
resistance to CAD is a cumbersome and time-consuming process ,
especially where large populations of germ-plasm stock have to be evaluated. There is theref ore the need to look into a rapid in vitro method of screening
cassava cultivars for CAD resistance
