In this study traits such as tiller number, plant height, flag leaf length, flag leaf width, flag leaf area, fresh and dry weight of flag leaf, stem and spike, stem diameter and SPAD, 1000 grain weight and grain yield were evaluated and measured. Based on the results of variance analysis, it was observed that there was a significant difference (at 1% probability level) between different genotypes of wheat based on all studied traits. Cluster analysis separated the studied genotypes into three distinct groups. Results of mean comparison between clustered groups showed that the third cluster had the highest desirable traits for photosynthetic characteristics including leaf length (30.07 cm), leaf width (1.54 cm), leaf area (35.22 cm2) and SPAD (46.33), fresh (3.06 g) and dry (1.07 g) weight of spike, fresh (1.29 g) and dry (0.42) weight of flag leaf, fresh (9.63 g) and dry (3.28 g) weight of stem, stem diameter (5.02 mm) and 1000 grain weight (48.51 g). Also, results of sensitivity analysis showed that genotypes in the third group had a stronger relationship with flag leaf fresh weight and SPAD traits with yield. Therefore, genotypes of the third group (nine advanced lines) can be used for future breeding programs.
