摘要：
The anthers of 10 Polish winter wheat (Triticum aestivum L.) cultivars were used for the induction of androgenesis and plant regeneration. The highest rate of callus induction (9.1%) and green plant production (0.8%) was obtained with the cultivar Apollo that was chosen for histological analysis. The first androgenic division was symmetrical and occurred after 3 weeks of culture. Further divisions of newly formed cells gave rise to multicellular structures which followed two developmental pathways: callus production or direct embryo formation. Plant regeneration was observed in both pathways. Chromosome counting of plantlets regenerated showed that haploid metaphases 2n=3x=21 were the most frequent.
