Vernalization Response of Some Winter Wheat Cultivars (Triticum aestivum L.)

J. Košner, K. Pánková

Czech J. Genet. Plant Breed., 2002, 38(3):97-103 | DOI: 10.17221/6242-CJGPB  

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...

Assessment of Frost Tolerance of Wheat Doubled Haploids by Gliadin Electrophoresis

I.T. Prášil, P. Prášilová, A. Šašek, J. Černý

Czech J. Genet. Plant Breed., 2002, 38(3):104-108 | DOI: 10.17221/6243-CJGPB  

The relationship between gliadin alleles, known to mark frost tolerance, and actual frost tolerance was investigated in 52 doubled haploids (DH) from the cross Florida× Vlada. 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...

Diversity of HMW-Glu Alleles and Evaluation of their Effects on some Characters in Winter Wheat Landraces and Old Cultivars

Czech J. Genet. Plant Breed., 2002, 38(3):109-116 | DOI: 10.17221/6244-CJGPB  

Earliness, morphological and agronomic characters and grain quality were studied in 123 European landraces and old cultivars of winter wheat in three-year field experiments. 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...

Characterization of Powdery Mildew Resistance Donors within Triticum boeoticum Accessions using RAPDs

J. Ovesná, L. Kučera, R. Bocková, V. Holubec

Czech J. Genet. Plant Breed., 2002, 38(3):117-124 | DOI: 10.17221/6245-CJGPB  

Wide hybridization has become a technique suitable for introgression of alien genes into modern wheat cultivars. 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,...

Curly Stem - an Induced Mutation in Flax (Linum usitatissimum L.)

E. Tejklová

Czech J. Genet. Plant Breed., 2002, 38(3):125-128 | DOI: 10.17221/6246-CJGPB  

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.

Use of STS Marker Linked to ym4 Gene for the Genotyping of Winter Barleys

V. Šudyová, M. Závodná, M. Hudcovicová, J. Kraic

Czech J. Genet. Plant Breed., 2002, 38(3):129-131 | DOI: 10.17221/6247-CJGPB  

The codominant STS marker MWG838, linked to BaYMV/BaMMV resistance gene ym4, was introduced into a winter barley breeding program. 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...
