Evaluation of the yield and its components in 20 bread wheat genotypes in Moghan

This experiment was conducted in order to evaluate the yield and its components with 20 wheat genotypes in a randomized complete block design with three replications in the Agriculture and Natural Resources Research Centre of Ardabil (Moghan) in 2012-2013. Six lines at a distance of 20 cm and a length of 6 meters was cultivated in each plot. Analysis of variance showed that significant differences were observed among genotypes for all traits except number of grains per spike. Data average comparison showed that the highest (3836) and lowest (2693) grain yield was related to genotypes 11 and 16. And genotypes 1, 2, 3, 7, 8, 9, 10, 11, 12, 14, 15, 19 and 20 was placed in class A and produced more grain yield. Data average comparison showed the highest grain weight per total plant accounted for genotype 8 with an average 10.40 g, while genotype 4 with an average 4.22 g had the lowest grain weight. It also showed that thousand grain weights (50.67 g) was related to genotype 19 among the genotypes studied. And genotype 4 with an average of 43.67 g produced the lowest thousand grain weight.
