    Opis:
    This study was performed to assess several indices for identifying genotypes at early growth stage with thebest performance in salinity conditions. In order to evaluate the biomass production of barley genotypes indifferent levels of salt conditions, an experiment was conducted as factorial arrangement with a completelyrandomized design with 3 replications. The effect of salinity treatments was studied through an analysis of thedry matter production, yielding results that show significant differences among genotypes. The majority ofused tolerance indices indicated that ESBYTM8910, 4 Shori and MBS8715 were the best barley genotypesshowing the highest stress resistance for the greatest NaCl concentration. Based on used stability parametersthe genotypes MBS8712 and Jo torsh were the most phenotypically stable. Result of cluster analysis revealedthat tolerant genotypes showed the least stability based on mostly of stability parameters. In general, resultsshowed the WB7910, ESBYTM8910 and MBS8715 genotypes appeared better than others across the salinitylevels.

    Opis:
    Aluminum toxicity is the major growth-limiting factor for crop cultivation on acid soils. Tolerance mecha-nisms for Al stress in triticale have not been systematically investigated so far. It is presumed, that in the case of this species they may be a function of the interaction between wheat and rye genes. In this study the se-quences of forty-six Diversity Arrays Technology markers associated with aluminum tolerance in triticale and under selection pressure were blasted against BLAST database for the identification of possible functions of the respective genome regions in Al-stress response. The analysis has showed sequences similarity to the domains involved in signaling, disease response and DNA repair mechanisms.

    Opis:
    Experiments were conducted to evaluate the genotypic variation for salt tolerance on seed germination for 24 genotypes (20 landraces and 4 breeding lines) of barley. The genotypeswere evaluated by several criteria, at 4 salt concentrations (0, 100 mM, 150 mM and 200 mM) and 4 seawater concentrations (0%, 20%, 30% and 40%). The results show a large variability within the genotypes for salt tolerance. Genotype × Treatment interaction is significant for root length. The estimates of broad-sense heritability calculated for percentage of germination (PG), percentage of emergence (PE) and radicle length (RL) were quite high for the salt treatment compared with those for the control treatment.Moderate to highBroad sens heritability estimateswere observed for the reduction percentage in both experiments. Discriminant analysis arranged the genotypes in two, clearly separate groups that differ in their tolerance to salinity stress.

    Opis:
    Fourteen hydroxyproline-resistant cell lines were selected by plating 7 days old cell suspensions of Solanum tuberosum L. cvs. Desiree and Maris Piper on a cell plating medium containing 5 or 10 mM hydroxyproline (hyp). Cell suspensions were either plated directly on selective media or after mutagenic treatment with gamma rays at a dose of 20 Gy or after freezing to –6°C. The frequency of resistant colonies varied from 0.15 to 0.35 x 10-6. Almost all the selected lines possessed increased levels of frost tolerance as compared to their non-selected controls except one indicating that hyp resistance and frost tolerance are not necessarily linked.

    Opis:
    Ten open-pollinated cultivars, two strains of rye and Sl, S2, S3 progenies obtained after selection directed towards tolerance to nutrient deficit were used in the study. The aim of the study was to compare the genotypes of the above mentioned rye populations by electrophoretically characterised of their secalin patterns.The result showed that most of the tested rye cultivars revealed simi1ar but not identica1 electrophoretic patterns. Specific secalin patterns were obtained from all the cultivars, except cv. Arant and strain SMH 92. Differences in comparison to initial genotypes were observed in some rye populations in Sl and S2 generations, including additional polypeptide of molecular weight 43 kDa. It was not linked with rye tolerance to nitrogen and potassium deficit in medium.

    Opis:
    The aim of presented work was to identify of PCR amplifiedDNAfragments differentiating aluminium tolerant and sensitive forms of rye and to locate the markers on rye chromosomes. For identification of markers, the PCR system with semi-specific primers targeting intron-exon sequences of plant genes was applied. The modified method of bulked segregant analysis was used. The pooled DNAs of two or three F2 segregating populations were screened together with DNA of their parental inbred lines. Potential marker of tolerance gene was located on rye chromosomes using wheat/rye (Chinese Spring/Blanco) additional lines. The specific probes obtained from DNA fragments differentiating sensitive and tolerant forms of rye were hybridized to PCR amplified DNA fragments of sensitive and tolerant forms of rye and the set of wheat/rye addition lines. Independently of the method of digoxygenin labelling (primer extension or Taq polymerase reaction), the probes obtained showed similar hybridization patterns. The results of hybridisation of 21 probes prepared from 12 DNA fragments confirmed connection of selected DNA fragments with to aluminium tolerance or sensitivity. Most of these DNA fragments originated from tolerant forms of rye. Using this method it was possible to locate eight DNA fragments on rye chromosomes. Three DNA fragments hybridised to chromosome 4R, two DNA fragments to chromosome 6R and single DNA fragments to chromosomes 1R, 2R and 3R. Four DNA fragments indicating clear relationship with character studied were not located on particular chromosomes using this set of wheat/rye addition lines. Hybridisation of probes prepared from four DNA fragments revealed length polymorphism. Probes prepared from two DNA fragments were characterised as dominant markers. In other cases the type of marker (dominant/codominat) was not fully documented.
