Determination of Yield and Quality Performance of Some Wheat Varieties in the Aydin Province

The purpose of this study is determined that yield, some yield components (the number of spikes per m2, spike height, number of grain per spikes and thousand grain weight) and some quality characteristics (rate of protein, oil, starch, fibre and ash) of some wheat varieties grown extensively in winter main crops in the Aydin province. The experiment was carried out at Adnan Menderes University, Faculty of Agriculture in 2017 and 2018. Cumhuriyet, Ceyhan 99, Ziyabey, Basribey and Golia produced the material of the study. As a result of the variance, the difference between years was found to be significant. It was measured that grain yield was in the range of 4000 kg ha-1 - 7060 kg ha-1, number of grain per spike was in the range of 26.3 - 40.8 and thousand grain weight and the number of spikes per m2 values were in the range of 31.9 g - 58.3 g and 400 - 555 respectively. The difference between years was more apparent in terms of grain quality characteristics. The protein averages of two years (17.0% - 14.7% respectively) were found to be higher than the required minimum value for bread wheat (12%) and the protein average of region (13% - 14%). Cumhuriyet proved its potential with protein (18.3%) in the first year and Basribey came to the fore with a high starch (63.2%) in the second year. Cumhuriyet and Ziyabey can be suggested for grain yield. Cumhuriyet has also come forward with its coarse grain structure (high thousand grain weight)
