Abstract

A comparative intraspecific study of Colletotrichum graminicola (Ces. ) G.W. Wilson from sorghum (Sorghum bicolor (L. ) Moench) was carried out. Thirtyone isolates were used, including 29 from various sites in Burkina Faso and 2 from the American Type Culture Collection tone from sorghum of Porto Rico and the second from maize of Alabama). The analysis of physiological (radial growth on agar media, biomass production, sensitivity to benomyl and pathogenic (virulence towards sorghum seedlings) characteristics revealed high differences between isolates for each variable. Single linkage cluster analysis showed that C. graminicola exhibits a continuous variability in Burkina Faso. Euclidean distances spread from 0.67 to 3.59 and isolates were distributed in dye distinct groups at a distance of 2.20 in the phenogram. Most isolates were found in one single group. The two control isolates from the American Type Culture Collection were apart from those of Burkina Faso,but were distinct one from the other as well. Neither the year of isolation, nor the isohyet of origin, nor the inoculum source (seed or leaf) seemedto be associated with the clustering of isolates.
