Abstract	The aim of this study was to analyse some characteristics of triticale flowering biology in Poland, during autumn 2002. Some 36 Polish cultivars of winter triticale were included in this experiment and compared to 2 winter wheat cultivars (Finezja and Soraja) and 2 winter rye cultivars (Amilo and Warko). To compare the fertility of spikelets measured by different types of pollination before the flowering, 10 single spikes and 10 double spikes were isolated for each triticale, wheat and rye cultivar. The results were compared to those from free pollination. After flowering, 10 spikes were picked from each triticale, wheat and rye cultivar to establish the percentage of the anthers remaining in particular florets of spikelets. Taking into consideration the number of the anthers getting outside of the florets, 3 types of flowering of the florets were distinguished namely open, closed and combined. Also, the participation of spikelets with different flower numbers in spikes was calculated. On the basis of the obtained results a great variation of analysed features in winter triticale cultivars was found. In spite of the differences among triticale cultivars, the analysed features of plant flowering showed a greater similarity to wheat than to rye. At the same time, a high percentage of open flowering of florets as well as throwing the pollen outside indicate the tendency of triticale to allogamy
