Investigation of yield, yield components and primary quality characteristics of some bread wheat (Triticum aestivum L.) genotypes

The aim of this study was to determine new wheat advanced lines with higher yield and better quality properties and to increase overall wheat production in Diyarbakir and surrounding regions with similar ecology. The experiment was carried out on 20 advanced lines and Dinç, Pehlivan, Cemre, Tekin and Ceyhan-99 as cultivars obtained from GAP International Agricultural Research and Training Center, during the growing season since 2015-2016 in the Diyarbakir, Turkey. The experiment was organized as randomized complete block design with three replications. Morphological and quality traits were considered: days to heading, plant height, chlorophyll content, peduncle length, number of spikes per square meter, spike length, number of spikelet per spike, number of grains per spike, grains weight per spike, grain yield, moisture content, thousand kernel weight, hectoliter weight, protein content, SDS sedimentation value, and wet gluten. There were significant differences among genotypes for all evaluated characters except number of spikes per m-2. The results also showed that advanced lines G1 and G3 and had the highest values in terms of quality parameters. In terms of grain yield the variety Tekin and advanced lines G6, G16, and G18 had the highest yield. To give an acceptable recommendation, the experiment should be repeated in more number of environments. Keywords: Bread wheat, correlation, grain yield, quality, yield components.
