The sugar cane cyst nematode Heterodera sacchari, Luc et Merny, 1963, has been found in rice fields in Nigeria (Babatola, 1983), the Ivory Coast (Merny, 1970) and Senegal (Fortuner and Merny, 1973). Its effect on the growth of rice has been demonstrated by Babatola (1983). This paper provides evidence of the different levels of susceptibility to H. sacchari of a range of rice breeding selections and cultivars.
