Abstract: 

Thirty six samples oftive maize hybrids including Ksc 301, Ksc 604, Ksc 647, Ksc 711 and Sc704 harvested from corn fields in east of Mazandaran province for two successively years. The samples were analyzed to detect and estimate Aflatoxin B1 B2. G1 and G2 by Romer TLC method. Aflatoxin B1 was detected in Ksc 301, Ksc 604 and Ksc 647 at alevel of 15 and 17.5, 35 ppb respectively in 1998.Aflatoxin B2was also found in Ksc 647 at level of 8.75 ppb. in 1997 Aflatoxin B1 was only detected in Ksc 301 at a level of29.17 ppb. Discolored and damaged corn seeds of the mentioned samples were cultured on PDA and humid filter paper to evaluate fungal contamination. The samples of Ksc 301, Ksc 604, Sc 704, Ksc 647 were contaminated with Aspergillus flavus at a level of 46, 16, 7 and 43% in 1998. Aspergillus flavus contamination was only detected in sample of Ksc301 at a level of 47% in 1997. This is the first report concerning natural occurrence of Aflatoxin in corn samples of iran.
