Opis:
F₁, F₂ populations as well as F₃ and F₄ wheat lines coming from more than 300 cross combinations have been used for androgenic wheat studies and more than 5000 haploid plants were produced. Promising doubled haploid lines were tested together with lines produced in the conventional way in yield trials. The two best doubled haploid lines overyielded the standard. On the basis of results related to the general combining ability it is advisible to cross parents with a good combining ability for characters such as high percentage of responding anthers and embryo/callus induction with parents indicating a good combining ability for green plant production. In this way ideal lines can be obtained for doubled haploid production.

Opis:
The influences of genetic and environmental factors on the anther culture responses of wheat were investigated. Significant differences for callus induction, plant regeneration, and green plant percentages were observed when the nucleus of Triticum acstivum L. cv. Selkirk was transferred to ten alien cytoplasms by substitution backcrosses. In most cases, the alien cytoplasms decreased anther culture responses, but sometimes they were as good as or better than the T. aestivum cytoplasm. Significant within-genotype variation for anther culture responses were observed for wheat varieties Chris, Yecora Rojo, WA7176 and Edwall, indicating genetic heterogeneity in the present commercial cultivars, and potential for improving anther culture responses by in vitro prescreening. When five genotypes (Chris, Pavon 76, Butte 86, WA6916, and Edwall) were cultured across three (potato-4 liquid, 100 g L⁻¹ ficoll-supplemented, and 6 g L⁻¹ agar-solidified) induction media, the liquid and ficoll-containing media were 10 to 15 times more productive than the agar-solidified medium. Whereas, the ficoll medium was not significantly different from the liquid medium. Several low concentration starch media appeared promising to replace current induction media. The starch media sustained the highcallus-induction properties of the liquid medium, while improving callus aeration similar to that observed on solid media, resulting in markedly higher plant regeneration and green plant percentages.

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.
