To evaluate physiological traits and traits related to grain quality of 18 triticale lines including 9 doubled haploid (DH) and 9 corresponding F6 lines, an experiment was conducted at research farm of College of Agriculture, Isfahan University of Technology located in Lavark- Najaf Abad in 2007. A randomized complete block design with 4 replications was used. Protein content, flour protein, gliadine, glutenin- secalin, SDS sedimentation volume, test weight, length, wide and area of flag leaf, chlorophyll content and grain yield were evaluated. The tested DH and F6 lines were significantly differed for most of studied traits with the exception of the SDS sedimentation volume, test weight, gliadine and length of flag leaf. F6 lines were superior that DH line for grain quality related traits. Significant and positive correlations were observed between grain yield and with length of flag leaf, while grain yield had a negative correlation with protein percentage and protein content, measured by spectrophotometer. The highest genetic coefficient of variation was observed for chlorophyll and the lowest one was for test weight, wide and length of flag leaf. The highest and the lowest broad heritability estimates were 99 ٪ for chlorophyll content and 28٪ for SDS sedimentation volume, respectively. Overall, F6 lines performed superior than DH lines for quantity-related and physiological traits.
