Abstract
During 2013, samples of infected seed grown caraway were collected from commercially grown crops in the experimental field in Mošorin and analyzed for the presence of plant pathogenic fungi. In all samples of seeds, weaker germination and a high seed infection 100%, with phytopathogenic fungi of the genus Alternaria, was found. From the infected caraway seed, monosporial cultures, based on morphology, were identified as Alternaria alternata, and their pathogenicity proved on artificially inoculated caraway and parsley seedlings. Molecular identification was performed utilizing polimerase chain reaction (PCR) with primer pair ITS1/ITS4 and by amplification of the ITS region of ribosomal DNA. Gene sequences of selected isolates CC1 (KP822948), CC2 (KP822949) i CC3 (KP822950) exhibited 100% nucleotide identity with the sequences of 31 isolates of A. alternata deposited in the GenBank. The presence of a large number of phytopathogenic fungi on caraway seed should be further investigated in order to clarify their relationships and relative significance.
