ESTIMATION OF YIELD AND PHYSICOCHEMICAL PARAMETERS OF ADVANCED LINES OF COMMON WINTER WHEAT IN THE REGION OF CENTRAL SOUTHERN BULGARIA

During the period 2016-2018 an investigation on the experimental field of IPGR “K. Malkov”, Sadovo was conducted. The investigations according to a block shame in three replicates with a size of the experimental plot of 10m² were performed. The grain yield is determined by standard grain moisture of 13%. Fourteen advanced breeding lines of common winter wheat ( Triticum aestivum L. ), Sadovo 1 and Enola varieties were evaluated. The evaluation of the quality indicators was carried out in the technological laboratory. The Enola variety (quality standard for the group B) was adopted as the standard variety. The main qualitaty indicators were monitored: 1000 kernel weight, test weight (kg/hl), sedimentation number, fermentation number, wet gluten content, relaxation of the gluten, bread making strength index and dry gluten. The physicochemical parameters of the studied breeding lines MX 270/3461, MX 270/3462, MX 270/3463, MX 270/3464, MX 274/717, MX 270/27 and YaiZlа meet the requirements of the high quality group A, the rest of the group B.
