Název v původním jazyce

Analysis of Leptosphaeria species complex causing phoma leaf spot and stem canker of winter oilseed rape (Brassica napus) in the Czech Republic

Popis výsledku v původním jazyce

This study comprised a large-scale survey of the occurrence of two closely related causal agents of the disease, Leptosphaeria maculans and L. biglobosa, in oilseed rape tissues and the country-wide distribution of each fungal species. There were 1159 leaf spots confirmed as infected by Leptosphaeria spp., with 65% of 907 L. maculans-type leaf spots infected by L. maculans only and 35% co-infected by both species, and with 88% of 252 L. biglobosa-type leaf spots infected by L. biglobosa only and 12% co-infected by both species. In 2007-12, 708 stems with phoma stem canker symptoms and 2635 plant tissues from upper stem, stem base, root collar and taproot of each stem were sampled for PCR. There were 1495 plant tissues confirmed as infected by Leptosphaeria spp., with the proportion of plant tissue in which only L. biglobosa DNA (62%) was amplified greater than that with only L. maculans DNA (11%) or with both L. maculans and L. biglobosa DNA (27%).
