Cultivars with high tannin content are being used as a source of resistance. However the interactions of tannins with proteins are responsible for the antinutritional effects of tannins-containing feeds that have been observed in nonrumiants. Jambunathan et al. (1986) have estimated the concentration of flaven-4-ols in mold-susceptible sorghum cultivars on grain and leaves. They also have established a positive association. The objective of this study was to identify resistant cultivars by using germination test and test weight, and to establish the relationship between these result and the concentration of flavan-4-ols under artificial inoculation
