| Abstract: | Vegetative compatibility using nitrate nonutilizing ( nit ) mutants was analysed between 44 isolates of Colletotrichum kahawae from Kenya, one each from Ethiopia and Malawi, one of Colletotrichum gloeosporioides and one of Colletotrichum acutatum . Another isolate of C. kahawae did not generate mutants and thus could not be utilized. The results showed that all the C. kahawae isolates, except a white sector mutant (VCG2), belonged to one vegetative compatibility group (VCG4). The other species belonged to their own unique groups (VCGs 1 and 3). Implications of the results and future research needs on the subject are discussed. |
