The spectrum of fungal diversity associated with rape seeds belonging to 33 cultivars (Alaska, Astrada, Astrid, Atlantic, Betty, Champlein, Chayenne, Dexter, Digger, Elvis, Eurowest, Finesse, Herkules, Hydromel, Hydromel-MA, Ladoga, Manitoba, Masa Rom, Milena, Mohican, Montego, Nectar, Ontario, Orkan, Perla (4 lots), Remy, Robust, Rodeo, Saphir, Tiger, Tiger CBC Lot ROM06-121-110, Triangle, Valesca, Vectra) and 2 hybrids (H-90-20-83, H-90-21-83) has been established by samples’ macroscopical and microscopical analizying, during 2006-2008, for the first time in Romania. The Ulster method on malt-agar and PDA culture media has been used, evaluating the percentage of fungal taxons present on/in rape seeds. The most important pathogenic fungi identified were: Sclerotinia sclerotiorum (Lib.) de Bary, Botrytis cinerea Pers., Rhizoctonia solani Kühn, Alternaria brassicae (Berk.) Sacc., A. brassicicola (Schwein.) Wiltshire and Fusarium spp. Also, a large quantities of some saprophytic fungi, as Alternaria, Cladosporium, Aspergillus, Penicillium, Rhizopus have been recorded. These ones have been affected the health condition of rape seeds, suppressing their germination and other vital phenomena. Among potential antagonistic fungi the followiung genera have been isolated: Chaetomium (0-4%), Trichoderma (0-10%), Aspergillus (0-14%), Penicillium (0-100%). Some correlations and comparisons have been established between fungal diversity, their provenience, cultivars, culture media (Malt-Agar/MA, Potato-Dextrose-Agar/PDA) used. It has been evaluated the behaviour of rape cultivars and hybrids towards the main rape seed pathogens.
