Androgenetic ability in euplasmic lines of common wheat and alloplasmic recombinant lines (H. vulgare)–T. aestivum carrying 1RS.1BL and 7DL-7Ai translocations and development of double haploid lines

Abstract

Androgenic ability was studied in anther cultures of euplasmic lines of common wheat and alloplasmic recombinant lines (H. vulgare)–T. aestivum with 1RS.1BL and 7DL-7Ai translocations. The ability to produce androgenic structures and plantlet regeneration are suppressed in lines carrying both translocations. Alloplasmic recombinant lines (H. vulgare)–T. aestivum with the 1RS.1BL and 7DL-7Ai translocations, as well as alloplasmic lines with the 1RS.1BL translocation, are characterized by their increased ability to form androgenic structures, including polyembryos, and plantlet regeneration compared to euplasmic lines. The inducing reciprocal influence of barley cytoplasm and rye chromosome 1RS on the androgenesis ability of lines (H. vulgare)–T. aestivum with 1RS.1BL and 7DL-7Ai translocations is discussed. Double haploid lines were developed from androgenic plants with spontaneously doubled chromosome numbers and restored fertility. Of the lines carrying the translocations, the most promising with regard to the exhibition of agronomic valuable traits and resistance to diseases were selected in order to utilize them in breeding programs.
