Plant-Pathogenic Fungi in Seeds of Different Pea Cultivars in Poland

Abstract

Legume crops are exposed to infection by fungal pathogens, which often results in contamination with mycotoxins. The aim of this study was to evaluate the level of field resistance/susceptibility of edible and fodder pea cultivars to the colonization of seeds by fungal pathogens in two subsequent seasons, as well as to identify the pathogens present in the seeds of the tested cultivars. Alternaria spp. were the most common fungi isolated from pea seeds in both seasons, followed by Fusarium spp., Stemphylium spp., Ulocladium spp., Botrytis cinerea Pers., Epicoccum nigrum Link., and Phomapinodella L. K. Jones. The highest percentage of infected seeds (55 %) was recorded for cultivar Ezop. The presence of a large number of fungi was found in 2012 for cultivars Santana, Tarchalska, Medal, Cysterski, Mentor, Lasso, and Ezop. Fodder cultivars displayed a lower infection level than edible cultivars. We can conclude that Alternaria spp. were the most frequent fungi present in pea seeds in Poland and Fusarium spp. were likely the most dangerous, having in mind their established mycotoxigenic abilities.
