    Taxonomic reconsideration of some Lactuca spp. germplasm maintained in world genebank collections.

  • Original language description

    In total 49 accessions of 24 wild Lactuca spp., a hybrid between L. serriola x L. sativa and the related species Mycelis muralis were evaluated with the aim to validate their taxonomic status. Based on morphological and other characters (e. g. chromosomenumber, relative DNA content, isozymes polymorphism) 17 germplasm accessions were reclassified. The majority of these 17 accessions was classified to the species L. serriola and as primitive forms of L. sativa. The taxonomic status of the other questionable Lactuca accessions is discussed in relation to their morphology. It was found after taxonomic revision, that the genetic variability of the genus Lactuca maintained in the genebank collection, represents 18 wild Lactuca species and cultivated L. sativa.

    Taxonomická redeterminace některých genových zdrojů rodu Lactuca uchovávaných ve světových genových bankách.

  • Czech description

    Soubor 49 položek 24 druhů rodu Lactuca a hybrid L. serriola x L. sativa a Mycelis muralis byly analyzovány s cílem upřesnit jejich taxonomický status. Z uvedeného množství bylo celkem 17 položek genových zdrojů přeurčeno. Většina z nich byla klasifikována jako druh L. sativa. Bylo zjištěno, že kolekce genových zdrojů rodu Lactuca zahrnují pouze 18 planých druhů a pěstovaný L. sativa.
