The response of F.moniliforme towards, different varieties of sorghum and maize for infestation and fumonisins production was investigated. In local variety of sorghum phenol content increased to 0.62mg/g in the infested seeds followed by 0.38mg/g to 0.81mg/g in CSH6. Increased reducing sugars in infested seeds was observed in local yellow variety (272mg/ g). Free amino acids content decreased however the degree of decrease varied with variety. High amounts of fumonisins was recorded in local yellowsorghumvariety (0.73g/ml). Increase in total phenols wasmore in white maize variety (0.38 to 0.90mg/g), free fatty acids was maximum in white variety (0.31 to 0.83). Kargil variety supported with lowamounts on fumonisins (0.38g/ml).Acareful consideration has to be made in selecting a seed variety for cultivation.
