Abstract: For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalization and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalization; different vernalization responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalization deficit exponentially: y = Parameter (1) + (y0 - Parameter (1)) × EXP (Parameter (2) × (x - x0)). The dependence was shown to be general and significant for the given model in all the studied cultivars. Individual regressions characterised responses of cultivars to a deficit of vernalization treatment. Cluster analysis according to the characterisation obtained (full vernalization requirement, minimum vernalization requirement, insufficient vernalization and parameters of the dependence) showed the relationships between cultivars and enabled their grouping by similar profiles of vernalization, and, possibly, of photoperiod response. In individual cultivars, an attempt was made to use the model to predict performance for some agronomic traits.

Frost tolerance was expressed as percentage of plant winter survival in pots placed at different heights above the ground. Gliadin allelic blocks (GLI) were determined by starch electrophoresis. From the six GLI, known as frost tolerance markers, the GLI 1B1, GLI 1D5 or GLI 6D2 was present in 27, 27 or 31 DH, respectively. A weak, but significant correlation of r = 0.29 was found in the DH between their survival and frost tolerance prediction values based on the presence of the gliadin frost tolerance markers. The average survival of DH with gliadin frost tolerance marker GLI 1B1 or GLI 6D2, but not with GLI 1D5, was significantly higher than the survival of DH without this block. The DH without any gliadin frost tolerance marker had the lowest survival. Some gliadin genes thus can be used as frost tolerance markers for preliminary selection of frost tolerant lines and for the study of physiological and genetic constitution of frost tolerance in common wheat.

Simultaneously, HMW Glu-alleles were identified in these cultivars by means of SDS-PAGE. Within this set of cultivars 224 Glu-lines (with occurrence over 5% in the cultivar) were identified carrying 3 different allelic combinations at 1A, 10 combinations at 1B and 3 combinations at 1D chromosomes, respectively. Relatively rare were alleles 2* at 1A and 3+12 at 1D as well as alleles 8, 6, 9, 7, 13+16 and 17+ 18 at 1B. Allele 20 at 1B was identified only in cultivars from DNK, CHE and EST. Allele 2* at 1A locus was found mainly in cultivars from Eastern, South-Eastern and Central Europe. Allelic combination 17+18 at 1B was also characteristic of cultivars from Central Europe. However, the gluten patterns themselves were not a sufficient tool for geographic characterisation of cultivars. The composition of Glu-alleles influenced the earliness of cultivars (alleles 2* at 1A, 17+ 18 and 6 at 1B and 3+12 at 1D). Spike length was positively affected by allele 1 at 1A and number of spikelets per spike by alleles 2+12 et 1D chromosome. Allele 2* was also associated with lower grain weight per spike. Crude protein content was decreased in cultivars where GS at 1A locus was absent (0). The value of gluten index was considerably higher (59.2) in cultivars bearing allelic combination 5+10 at 1D. A number of alleles affected the values of SDS micro-sedimentation test.

Ten Triticum boeoticum Boiss. accessions resistant to powdery mildew were studied in more detail. Variability between the accessions was studied using resistance tests, RAPD and storage protein analysis. Potential gene recipients (T. aestivum and T. durum cultivars) were also included. Unlike protein analysis we were able to clearly distinguish among the individual accessions of T. boeotium using RAPD. Computed dendrograms reflect phylogenetic relationships among the characterized species. All tests proved, that T. boeoticum is a valuable gene-pool. Three T. boeoticum × T. durum amphidiploid progenies were also analysed. They differ in the degree of resistance to powdery mildew. Both RAPD and storage protein analyses indicated that genome rearrangements occurred. We showed, that RAPD could be used to trace such events.

Abstract: After ethyl methane sulfonate (EMS) treatment of two flax lines, curly stem mutations appeared in both, besides of other mutations. Genetic analysis of one CS mutant line confirmed a monogenic inheritance of the changed stem shape. The curly stem allele is partially dominant over the wild type allele for straight stem. Homozygotic mutants have a curly stem, heterozygotic plants have a flexuous stem, while the stem of homozygotic recessive plants is straight. The expression of the curly stem character is affected by factors influencing plant growth. The utilisation of this mutation for ornamental and other purposes is considered.

Lines of F2 and F3 progenies were created from crosses of the gene ym4 donor genotype Romanze and five different gene acceptors. Homozygous recessive, homozygous dominant, and heterozygous individuals were clearly identified and selected within F2 individuals by the used DNA marker linked to ym4 gene. F3 lines created by self-pollination from selected ym4ym4 F2 genotypes were reverified and included into further testing and breeding. The ym4 gene-linked presence of DNA marker was confirmed in progenies from all parental combinations.
