A serie of experiments was conducted to assess the relationship among grain molding fungi species within each grain mold rating. Seed samples from a field evaluation of 131 F2-derived F5 recombinant inbred families at eight environments were collected to isolate grain mold fungal flora. At each environment grain mold was recorded on a 1 to 5 scale at 40-45 days after flowering. The most prevalent molding fungi specie isolated was Fusarium verticillioides, which accounted for 46% of the total fungi species recovered. C. lunata was negatively correlated with Alternaria spp. and Dreschlera sp., F. verticillioides was negatively related with Alternaria sp. and positively related with C. lunata. A positive correlation was observed between the predominance of F. verticillioides and C. lunata with germination. A Spearman rank-order correlation determined negative relationship between scoring rates and seed germination and a positive relationship between seed germination and fungal species diversity. Principal component analysis indicates that as grain mold ratings increase, so does fungi interaction complexity. Knowledge about fungal flora present in different grain mold rating scores allows making inferences about the most predominant fungi species, the most important interactions among those species and may help to enhance selection process for resistant varieties.
