Název v původním jazyce

Characterization of new highly virulent German isolates of Bremia lactucae and efficiency of resistance in wild Lactuca spp. germplasm.

Popis výsledku v původním jazyce

Four German isolates (FS1, SR2, SAW1 and DEG2) of Bremia lactucae originating from lettuce cultivars with R-factors R18 and DM6 + R36 were used for detailed characterization of virulence factors (v-factors) and for the study of resistance efficiency in wild Lactuca spp. germplasm. The highest complexity of v-phenotype was recognized in isolate DEG2, which overcomes resistance in cv. Mariska (R18) and line CS-RL (L. serriola x L. sativa, R18 + ?), until now known as resistant to all known races of B. lactucae in Europe. The search for efficient sources of resistance in 64 accessions of 11 wild Lactuca spp. and primitive forms of L. sativa showed broad variation in accession-isolate interactions.
