This study was conducted in Hatay-Reyhanlı conditions during 2017-2018 plant growing season to determine the effect of seeding rate effect on the yield and some quality characteristics of bread wheat cultivars. Six bread wheat cultivars (Karatopak, Seri-2013, Osmaniyem, Yakamoz, Sagittario and Masaccio) and three seeding rates (450, 550 and 650 seeds m-2) were tested. The experimental design was split plot arranged completely randomized block design with three replications. Seeding rates was settled in main plots and cultivars were settled in sub plots. Heading date, plant height, spikelet number, kernel number per spike, fertile tiller number, grain yield, thousand kernel weight, protein ratio, wet gluten ratio and sedimentation values were investigated. Seeding rates x cultivar interaction was significant in terms of heading dates, grain yield, and protein ratio. Cultivars were significant in terms of heading date, kernel number per spike, kernel weight per spike, grain yield, protein ratio, wet gluten ratio and sedimentation value. As the seeding rates increased the duration of the heading period was shortened, fertile tiller number and protein ration were decreased. In terms of seeding rates the highest grain yield of 5592 kg ha-1 was obtained from seeding rate of 550 seed m2, followed by 650 seed m-2 with 5200 kg ha-1 and 450 seed m-2 with 5194 kg ha-1. In terms of cultivars, mean grain yield varied between 6526 kg ha-1 (Yakamoz) 4567 kg ha-1 (Karatopak). Our results showed that seeding rates was an effective environmental factor affecting yields and quality of bread wheat cultivars at varying rates.
