Studium variability DNA u tribu Triticeae
Vintrlíková, Nikola
This work is focused on the study of genetic variability of chosen genotypes of tribus Triticeae. 9 genotypes of common wheat and 2 genotypes of tritordeum by 12 microsa-tellite markers were studied. We found 71 alleles whose size ranged from 110 to 260 bp. For every SSR marker were calculated the diversity index (DI), the probability of identi-ty (PI) and the polymorphic information content (PIC). Dendrogram was constructed on base of statistical evaluation The genotypes of tritordeum were statistically significantly separated from wheat genotypes. Individual plants from 2 crosses between wheat and tri-tordeum using highly polymorphic marker Xbarc077 were analyzed. Results show that the crossing was successful only for one set of analyzed plants (JB1 × Elly). SSR markers are useful for detecting genetic variability in the Triticeae tribe and detecting the success of hybridization.
