However, genotypic potential of yield related traits of single-planted wheat may differ with the plants grown under canopy pressure. A field experiment was conducted during two consecutive years to assess the relations between grain yield parameters of single-planted and field-grown wheat plants. The experiment was installed in a randomized complete block design with 3 replications and 8 bread wheat cultivars were used. Plant height, biomass, spike number, grain number, thousand grain weight and grain yield were determined under both conditions. Average grain yield decreased from 2.90 ton/ha in 2012 to 1.71 ton/ha 2013. Although grain weights of single-planted wheat also decreased in the second year (2.83 g/plant) comparison to first year of the experiment (4.93 g/plant), varied response were found among genotypes under single-planted and with in-canopy conditions.</span><br></p>
