The study of genetic diversity of wheat genotypes based on Gliadin protein patterns

In order to study the reaction of winter wheat genotypes to drought stress in terminal, an experiment was conducted with 9 wheat promising lines and Shahryar varieties (control) in a randomized complete block design with three replications. In addition to morphological assessment in the field, gliadins electrophoresis was performed using the technique A-PAG in the laboratory. There was significant difference between genotypes in terms of all properties evaluated. The highest yield belonged to genotypes 2, 3 and 4 with 9/3 and lowest in genotype 5 with 1/2 ton ha. The relationship between traits showed that the increasing of peduncle length and reducing the number of fertile tillers will have a positive effect on performance. Due to the high correlation of grain yield with grains per spike indicated that these traits can also be a good measure for the selection of high yielding varieties. In grouping, according to the jacquard distance and cluster analysis based on protein data in genotype 4 which is, yielding, fast flowering and preterm, short legs, high claws which had high hyacinths length, had the farthest distance with the other genotypes is being studied.
