Opis:
The aim of the research was to assess the androgenic potential of 21 Polish cultivars of spring and winter barley. On average, a few green plants developed per 100 anthers. Cold pretreatment proved conducive to the formation of embryos/calli, while mannitol pretreatment favoured green plant development. The first embryos/calli formed on the induction medium developed most efficiently. The authors chose FHG medium supplemented with 1 mg/l BAP and 0.2 mg/l 2,4-D (induction of androgenesis) and FHG medium supplemented with 0.4 mg/l BAP and 3% maltose (plant development).

Opis:
Using in vitro androgenesis serves as a unique opportunity to produce doubled haploid (DH) plants in many species. More benefits of this biological phenomenon have kept these methods in the focus of fundamental research and crop breeding for decades. In common wheat (Triticum aestivum L.), in vitro anther culture is one of the most frequently applied DH plant production methods. The efficiency of in vitro wheat anther culture is influenced by many factors, such as the genotype, growing conditions, collection time, pre-treatments, and compositions of media and culture conditions. According to some critical review, the genotype dependency, low efficiency and albinism are mentioned as limitations of application of the anther culture method. However, some research groups have made significant efforts to diminish the effects of these bottlenecks. Due to the improvements, a well-established in vitro anther culture method can be an efficient tool in modern wheat breeding programs.

Opis:
Anthers of twenty triticale genotypes were cultured on three different media: 1 - PII (Chuang et al. 1978) with increased 2,4-D to 2 mg L⁻¹ and agarose 6 g L⁻¹ , 2 - Macro-, micronutrients and vitamines like in MN6 (Chu, Hill 1988) + 2 mg L⁻¹ 2.4-D + 0.5 mg L⁻¹ KIN + 5 mg L⁻¹ FeEDTA + 90 g L⁻¹ sucrose; 3 - Macro-, micronutrients and vitamines like in MN6 (Chu, Hill, 1988) + 2 mg L⁻¹ 2.4-D + 0.5 mg L⁻¹ KIN + 5 mg L⁻¹ FeEDTA + 120 g L⁻¹ sucrose. Embryoid induction and plant regeneration were influenced by donor plant genotype and induction medium. Medium 1 was the best for embryoid induction, while for green plant regeneration the best were media 1 and 2. Out of 300 anthers from each genotype plated on each of the three media, 64-1250, 12-486 and 6-212 somatic embryos and 8-86, 3-136 and 1-26 green plants were recorded, on media 1, 2 and 3, respectively.

Opis:
The aim of the work was to determine how the induction of androgenesis in selected genotypes of Salix viminalis is affected by thermal factors and medium composition. Anthers isolated from male clones of S. viminalis were pre-cultured at 4, 27 and 32°C for two to eight days in liquid Kyo medium with and without the addition of mannitol and on solid MS or WPM medium. The solid media were supplemented with different concentration of disaccharidesand various combinations of growth regulators including kinetin, 2iP, IAA and IBA. Multi-nucleate microspores indicative of androgenesis were observed in anthers pre-cultured for seven days at 4°C in liquid Kyo medium containing mannitol. The rate of androgenesis was higher when the anthers were transferred to solid modified MS medium containing high concentrations of sucrose and kinetin. In studied genotypes of basket willow early uninucleate microspores underwent sporophytic divisions. Ultrastructural observations showed differences in cellular arrangement of pre-stressed microspores. In Salix viminalis, microspores without starch grains and decreased number of lipid bodies were potentially androgenic cells.

Opis:
Recent advances at Institute of Grassland and Environmental Research (Aberystwyth, U.K.) in cytogenetics of the Lolium/Festuca complex places us in the advantageous position of being able to map genes of agronomic importance onto chromosome arms using fluorescence in situ hybridization (FISH). The ability to physically map genes leads to the capability for "dissecting" quantitative traits into their different components and will lead to better understanding of the complex physiological processes involved and the identification of their genetic control. By tagging genes of interest, using molecular and morphological markers, it will be possible to select and combine suites of desirable genes in a single genotype and thus produce novel cultivars by conventional breeding procedures. Programmes for introgression depend on the relationships between species and on levels of chromosome pairing. Phylogenetic relationships within the Lolium/Festuca complex are being determined using both genomic in situ hybridization (GISH) and FISH. With recent advances in genetic manipulation within the Lolium/Festuca complex, opportunities now arise for gene transfer from Lolium and Festuca species into other important agricultural crops.
