Title: Relationship of Fusarium fungi associated with ear rot and stalk rot in maize by RAPD technique
Abstract: Random amplified polymorphic DNA (RAPD) was used to analyze the relationship of Fusarium fungi collected from ear rot and stalk rot. High degree of homology was found between the isolates of Fusarium moniliforme from ear rot and the ones from stalk rot. No correlation was found between genetic variation of F. moniliforme and disease-occurring areas, environmental factors and plant organs, suggesting that F. moniliforme may be the common pathogen of ear rot and stalk rot. On the contrary, the isolates of Fusarium graminearum from ear and stalk were genetically varied with disease-occurring areas, environmental factors and plant organs. The ear rot and stalk rot can be caused by a single strain of F. grami- nearum as well as by mixed strains of the fungus.
