Moench) accessions exhibiting contrasting reactions to the grain moldcomplex were grown in two consecutive rainy seasons at the International Crops Research Institutefor the Semi-Arid Tropics, Patancheru, India. Methanol and acidified methanol extracts of grainsharvested at different grain development stages were analyzed for flavan-4-ols. The concentrationsof flavan-4-ols in mold-resistant grains were at least 2-fold higher than in mold-susceptible grains inboth extracts at or after 30 days of flowering. Concentration of flavan-4-ols in mature, grain sorghumscould, therefore, be an indicator of their potential resistance or susceptibility to grain mold,and this method could be an important tool in screening sorghum cultivars for such characteristics
