The trial was conducted for a 5-year period (2019-2023) on the experimental field of irrigated agriculture experimental station Pazardzhik. In the period 2019-2023 in the field of irrigated agriculture experimental station Pazardzhik on cinnamon forest soil at humus 1.2-1.5% and pH 5.5-6 is set trial, which includes 9 varieties of common winter wheat selection of IPGR Sadovo. It was laid out using the long strip method in four replications with a harvest plot size of 10 m2. The sowing rate is 550 gs/m2. Fertilization was with phosphorus (20 kg/da), applied as triple superphosphate pre-sowing. The entire nitrogen fertilizer rate was applied as N12 (applied as ammonium nitrate). The quality parameters sedimentation value; grain vitreousness; fermentation number; crude protein; wet gluten content; gluten release, dry gluten; bread making strong index were monitored in the grain quality laboratory at IPGR, Sadovo. Gluten relaxation, baking stomg index and dry gluten were determined. ANOVA, Duncan test, cluster and correlation analysis were used for mathematical treatment of data.
