1 The rhizome discolouration index (RDI) was scored on a rating scale ranging of 1 to 6, with 1 indicating no internal symptoms and 6 indicating the discolouration of the entire inner rhizome. 2 Means with the same letter within the same column do not differ significantly according to Fisher’s test of least significant differences (p < 0.05). 3 RDI in the screen house was rated 10 weeks after inoculation. 4 Mbwazirume and Sukari Ndizi were used as resistant and susceptible control respectively.
