Among the 194 isolates screened from 127 cereal samples, 176 were fumonisin producers and others were non-producers. Representative nine strains along with one reference standard strain MTCC156 were selected to study their morphological, pathological and mycotoxicological variations by conventional and molecular approaches. strains FVM86, FVM146, FV200 and FVS3 showed significant pathogenicity and also in pigmentation production but varied in fumonisin production. strain FVP19 recorded variations in all the assays. strain FVM42 showed drastic phenotypic variation and it also produced fumonisin. Genetic variation among the strains was independent of geographic area of origin but depended on their ability to produce fumonisin. The strains were independent in their cultural characteristics, pigmentation production, pathogenicity assays, fumonisin production and in their genetic variability without having any correlation.
在从127份谷物样本中筛选出的194株分离株中，176株产生伏马毒素，其他为非产生株。选择具有代表性的9株菌株以及1株参考标准菌株MTCC156，通过传统方法和分子方法研究它们的形态、病理和霉菌毒素学变异。菌株FVM86、FVM146、FV200和FVS3表现出显著的致病性，在色素产生方面也有差异，但伏马毒素产生量不同。菌株FVP19在所有测定中均有变异。菌株FVM42表现出剧烈的表型变异，且也产生伏马毒素。菌株间的遗传变异与起源地理区域无关，但取决于它们产生伏马毒素的能力。这些菌株在培养特征、色素产生、致病性测定、伏马毒素产生以及遗传变异性方面相互独立，没有任何相关性。
