Double Haploids

The objective of the study was to investigate efficiency of anther culture in the production of spontaneous double haploids from randomly selected heterozygous genotypes of wheat (Triticum aestivum L.). Anthers of 20 F1 wheat combinations were grown in vitro on a modified Potato-2 medium. All of the examined genotypes have shown the ability to produce pollen calluses as well as to regenerate green plants. On average for the whole experiment material, 47.2 calluses were produced per 100 cultured anthers. The green plant regeneration ranged from 0.8 to 13.4 green plants per spike, with an overall mean of 5.8. From the total of 582 regenerated green plants, 47.9% (279) were spontaneous double haploids. The final average yield from the study was 2.8 double haploids per spike.

We investigated the anther culture (AC) efficiency of thirteen F<sub>4</sub> combinations of winter wheat (Triticum aestivum L.). The genotype dependency was assessed during the induction of the androgenic entities, i.e. embryo-like structures (ELS), regenerated-, green-, albino-, and transplanted plantlets. The number of green plantlets per 100 anthers (GP/100A) varied from 0.36 to 24.74 GP/100A with a mean of 8.31 GP/100A. Albino plantlets (AP) occurred in each combination, ranging from 0.20 to 22.80 AP/100A with an average value of 5.59 AP/100A. Between 25–87.76 doubled haploid (DH) plants per 100 acclimatised plantlets (DH/100ADP), depending on the combination, with a mean of 59.74% were recovered. We have found the highest DH production in the combinations Béres/Midas, Kalász/Tacitus, Béres/Pamier, and Premio/5009. This improves remarkably the choice of basic genetic material in subsequent crossing programmes. These observations emphasise the usability and efficiency of in vitro AC in producing a large number of DH lines for breeding and the applied researches of winter wheat. Although albinism was found in each combination, it was mitigated by the in vitro AC application.

Haploid Production

In vitro anther culture is the most commonly-used technology for doubled haploid production in wheat (Triticum aestivum L.) and various cereals. The technology application allows the genetic attainment of homozygous pure lines from heterozygous breeding material in a single generation, and has become a rapid alternative to the conventional breeding methods. This technology also contributes to more accurately assess QTL × environmental interactions and has been applied in: genetic researches for marker-trait association study, genomics and as a target for transformation, genetic engineering, gene mapping, and mapping of quantitative trait loci (QTLs). This paper reviews the most important factors that limit the efficiency of winter wheat (Triticum aestivum L.) anther culture, such as genotype dependency and albinism, in addition to other affecting factors including the collection time of tillers and physiological growth environments of plants. Factors that improve the efficiency of wheat anther culture in mitigating both genotypic dependency and albinism have been included in this review, too, for example, genetic improvements by following a strategy to realize this purpose through using responsive breeding material for crossing, application of convenient stress pre-treatments (cold pre-treatments, heat shock treatment, colchicine, hormones, and chemicals) to induce androgenesis, and improvement of the composition of anther culture media and culture conditions. We have also highlighted the methods of chromosome doubling for the haploid wheat produced by anther culture androgenesis, such as spontaneous chromosome doubling or use of colchicine and anti-mitotic chemicals at an early stage of anther culture or as root immersion treatment.

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.
