The mycoflora, germination, and electroconductivity of ten samples of wrinkled seeded peas, both non-pretreated and pretreated were investigated. Twenty nine species and genera of fungus were identified. Penicillium spp., Aspergillus spp. and Alternaria alternata were dominant ting among them. Among Ascochyta spp., A. pisi prevailed. Ascochyta spp., Fusarium spp. and the fungi which occurred the most often were included in statistical analysis separately and all the others were put into one group called "others". The percentage of fungi detected on/in the seeds was significantly correlated with both germination (R=0.97 and 0.98 for non-pretreated and pretreated seeds, respectively) and electroconductivity (R=0.96 and 0.93). Alternaria alternata, Penicillium spp. and other fungi had the most significant joint effect on germination of non-pretreated seeds while Aalternata, Aspergillus spp., Penicillium spp. and other fungi jointly most significantly affected germination of pretreated seeds. Electroconductivity of non-pretreated seeds was the most significantly affected by other fungi while that of pretreated ones jointly by Aspergillus spp., Fusarium spp., Penicillium spp. and other fungi.
