Aim. Receiving of genetically modified plants of bread wheat with heterologous ornithine‑δ‑aminotransferase gene. Methods. Agrobacterium-mediated transformation of callus cultures in vitro, PCR-analysis. Results. By Agrobacterium-mediated transformation of the morphogenic calluses of bread wheat (Triticum aestivum L.) using the AGLO strain containing the binary vector pBi-OAT with the target ornithine-δ-aminotransferase (oat) and selective neomycinphosphotransferase II (nptII), transgenic plants-regenerators have been obtained. Conclusions. As a result of the genetic transformation of Zimoyarka variety, 12 wheat regenerants were obtained in the genome which revealed a complete integration of the genetic construct containing the oat and nptII transgenes. Keywords: Triticum aestivum L., Agrobacterium-mediated transformation, ornithine‑δ‑aminotransferase gene, PCR-analysis.

A high-performance protocol for callus induction was devised using germinating mature embryos of two local wheat (Triticum aestivum L.) landraces as explant. The results showed that callus development from germinating embryos was rapid starting one day after culture with an induction rate 20 to 25% higher than those of soaked embryos. In addition, the mean rate of growth of callus developed from germinating embryos was 60 to 70% higher than those cultured from soaked embryos. This study also demonstrated a higher frequency of green spots formation(48 to 56%)on callus derived from germinating embryos compared to their soaked counterpart (24 to 28%), suggesting a better differentiation potential of callus cultures derived from germinating embryo. These findings indicate that germinating mature embryo is more suitable explant for wheat callus induction and regeneration than the soaked mature embryo commonly employed for wheat callus culture.
