BACKGROUND AND AIMS Aegilops markgrafii (CC) and its natural hybrids Ae. triuncialis (U(t)U(t)C(t)C(t)) and Ae. cylindrica (D(c)D(c)C(c)C(c)) represent a rich reservoir of useful genes for improvement of bread wheat (Triticum aestivum), but the limited information available on their genome structure and the shortage of molecular (cyto-) genetic tools hamper the utilization of the extant genetic...

Magyarország Flóratérképezési Programja során 2012-ben 9 kvadrát felmérését vé­geztem el a Jászságban. Az adatgyűjtést 2020-ban kiegészítettem. Cikkemben az érdekesebb, regionáli­san fontos florisztikai adatokat közlöm 68 edényes növényfajra vonatkozóan. Közöttük vannak idegen­honos taxonok (pl. Alopecurus myosuroides, Amaranthus deflexus, Juncus tenuis, Phytolacca esculenta) országosan (Silene...

We have recently produced EMS-induced knock-out mutations at the Gc2 locus that were derived from Ae. sharonensis. Our data suggest that the Gc2 mutant is a knock-out of the gene encoding for the breaking agent. For analyzing the interactions of the Gc2 mutants with other Gc genes from different Aegilops species, we have crossed stocks with functional and mutant Gc2 genes with stocks having Gc ...

A gametocidal chromosome, chromosome 2C derived from Aegilops cylindrica, was introduced into six wheat-barley addition lines to establish chromosome-mutationinducing lines. These lines, except the one for chromosome 4H, had a pair of respective barley chromosomes and one 2C chromosome (22”+1’); the line for 4H was doubly monosomic for chromosome 4H and chromosome 2C (21”+2’). In these lines, c...

in this study, 110 samples of bread wheat, aegilops crassa, ae. cylindrica and ae. tauschii were investigated to identify low-molecular-weight glutenin subunits. overall, the four alleles in term of the analysis of sds-page gels were detected. the ʻaʼ allele with 45% has the greatest frequency, and after that, ʻbʼ, ʻcʼ and ʻdʼ alleles were with 38.1%, 11.8% and 9.1% frequencies, respectively; h...
