Özet:

This study was carried out in Kahramanmaraş ecological conditions in the 2020-2021 growing season in order to determine the differences among yield and yield components in some cereal species (triticale, wheat, barley and oat). The fertile tiller number (number), hectolitre weight (kg), bunch/spike grain number (number), bunch/spike grain weight (g), thousand seed weight (g) and grain yield (kg da-1) characteristics of cereal species were taken into consideration. Except for the number of fertile tiller, significant differences were found among the winter cereals in other characters. Wheat (68.24 kg) and triticale (67.45 kg) gave the highest values in terms of hectolitre weight. The number and weight of bunch/spikes gave the highest triticale values (25.27 number and 1.16 g, respectively). Oats (28.35 g) and triticale (26.86 g) took the first place in terms of thousand kernel weight. Wheat (702.96 kg da-1) had the highest grain yield, followed by barley, triticale and oats. According to the results, it has been seen that there are differences among the cereal species considered in terms of yield and yield components in Kahramanmaraş conditions and the order of the species in terms of characters has changed.
