Description
  • Předmětem naší práce bylo studium variability virulence populací B. lactucae vyskytujících se v porostech pěstovaného salátu na území České republiky. Ke studiu bylo použito celkem 55 izolátů B. lactucae získaných v letech 2000-2005 na 27 lokalitách České republiky z přirozeně infikovaných rostlin kulturního salátu. Pro vyjádření virulence a popis studovaných izolátů byla použita metoda sextet kódů (van Ettekoven a van der Arend, 1999). Výsledky testů ukazují, že v populacích plísně salátové v porostech L. sativa existuje poměrně značná variabilita virulence. Celkem bylo rozlišeno 22 ras s odlišným sextet kódem. Společným rysem studovaných izolátů byla jejich silná virulence vůči genotypům L. sativa a vysoká komplexita virulence, tj. schopnost překonávat všechny základní geny rezistence. (cs)
  • Our present paper is focused on study of virulence variation in populations of B. lactucae occurring on lettuce (Lactuca sativa) in the Czech Republic. Totally 55 isolates of B. lactucae collected during period 2000-2005 were screened. Virulence patterns of the studied isolates were described using sextet codes (van Ettekoven a van der Arend, 1999). Results show that there is a broad variation for virulence in populations of B. lactucae occurring on cultivated lettuce. Totally 22 races differing in their sextet codes were recognized in the studied set of isolates. The common feature of all screened isolates was their high virulence to lettuce and high virulence complexity of described races.
