Formation of the quality potential of winter common wheat varieties under the influence of the applied herbicides
Sonya Donevaorcid, Zornica Petrova
Abstract: The results of the present study present the formation of the quality potential of three varieties of common wheat (Tr. aestivum L.), belonging to different quality groups - Rada, Kosara and Pchelina, under the influence of the specific conditions of the Dobrudja Agricultural Institute - General Toshevo, and the application of herbicides from the group of sulfonylureas – Ergon WG (5 g/da), Starane Gold (180 ml/da), Biatlon 4d + Desh (5 g/da+50 ml/da), Corello Duo + Dasoil (26.5g/da+50ml/da). The research was conducted in the period 2019 - 2021. The changes in the sedimentation volume, yield of wet gluten and dry gluten in 70% flour, the physical properties of the dough and the baking qualities of the analyzed varieties were monitored. It was found that the genotype factor has the strongest influence on all quality indicators. Most significantly, the weather conditions of the harvest year affect the sedimentation volume, the dough formation time, the quality number from the farinograph, the volume of the bread and its shape stability. The herbicides applied in the experiment have a statistically significant effect on the indicators of sedimentation, wet gluten, degree of softening and dough development time. The preparations Starane Gold and Biathlon 4D + Desh increase the average values of sedimentation in all three varieties, regardless of the weather conditions of the year, and Ergon WG and Corello Duo + Dasoil reflect on this quality indicator depending on the genotype. All three varieties have a high content of wet gluten yield (WG) when treated with Ergon WG herbicide. The time for dough formation is shorter in Rada and Pchelina varieties under the influence of Corello Duo + Dasoil. A similar tendency to increase the degree of softening under the influence of all applied herbicides was found for Kosara and Pchelina, while for the Rada variety the effect of the preparations was different - Ergon WG and Corello Duo + Dasoil decreased, and Starane Gold and Biathlon 4D + Desh increased the average values of the analyzed indicator. Genotype x herbicide and genotype x year interactions had a weaker but statistically significant effect on most of the technological parameters, while herbicide x year and genotype x herbicide x year interactions did not significantly affect the quality characteristics of all three cultivars.
