A new gametocidal gene was found in a common wheat cultivar Chinese Spring carrying the cytoplasm of Aegilops speltoides strain KU 5725 (Plant Germplasm Institute, Kyoto University). Monosomic analysis revealed that this gene and a previously known gametocidal gene Gc1, both derived from Ae. speltoides, are located on chromosome 2B. The two genes appear to be allelic and so have been designated as Gc1a (previous gene) and Gc1b (present gene). The two genes differ in their ability to induce hybrid dysgenesis in wheat: Gc1a causes endosperm degeneration and chromosome aberrations, whereas Gc1b results in abnormal seed lacking the shoot primodium. No correlation between embryo or endosperm degeneration and chromosome breakage was observed.Key words: wheat, Aegilops speltoides, gametocidal gene, hybrid dysgenesis, chromosome breakage.

Aim. The aim of this study was to isolate and propagate mutants at gliadin loci developed on the basis of the common wheat cultivar Bezostaya 1. Methods. We searched for spontaneous and gamma-irradiation induced mutations at gliadin loci among the progeny of F1 and F2 plants from crosses between near-isogenic lines by gliadin loci on the basis of the cultivar Bezostaya 1, including lines with the wheat-rye 1BL.1RS translocation. To identify mutations, we performed acid polyacrylamide gel electrophoresis and SDS-electrophoresis of storage proteins. Results. On the basis of the common wheat cultivar Bezostaya 1, five mutants (six mutations) at gliadin loci were isolated and propagated, four of which were described for the first time. Three mutations occurred at the Gli-R1 locus involved in the wheat-rye 1BL.1RS translocation (the loss of secalins, intensification of a secalin component, and increased mobility of a secalin component). Two mutations were identified in the allele Gli-B1b, one caused the null-allele at the Gli-A2 locus. Conclusions. The material of mutants is of importance for studying the role of certain groups of storage proteins and their components in quality determination, as well as mechanisms of regulation of storage protein synthesis. Keywords: Triticum aestivum, gliadin, secalin, mutation, 1BL.1RS translocation.
