| Summary: | The article presents the study results of winter soft wheat lines in competitive variety testing according to productivity and grain quality indicators. The study was conducted at the experimental plot of the laboratory of the breeding and seed-growing of winter soft wheat of intensive type in the FSBSI “Agricultural Research Center “Donskoy” in 2016–2018. 47 winter soft wheat samples of competitive variety testing were used as the studied material. The winter soft wheat variety “Ermak” was used as a standard. Over the years of study 23 lines exceeded productivity of the standard variety “Ermak”, the increase ranged from 0.49 to 1.66 t / ha on average. The maximum protein percentage in grain was formed by the samples “1992/16” (13.5%), “1221/16” (13.5%), “1914/16” (13.6%), “1788/16” (13.9%), “2030/16” (14.0%). The lines “1854/16” and “1990/16” combining high yields (11.17–11.30 t/ha) with protein percentage of 12.9–13.2% are of great interest for breeding. The highest content of gluten in the grain (29.3–30.0%) was identified in the samples “1992/16”, “1914/16”, “2030/16”, “1221/16” and “1093/16”. There were identified the lines “1385/16”, “1533/16” and “1862/16”, combining high yields (11.20–11.59 t/ha) and 27.9–29.1% of gluten in grain. The highest value of SDS-sedimentation (66–70 ml) was found in the samples “1093/16”, “1990/16”, “2079/16”, “1533/16” and “1987/16”. The lines “1547/16”, “1385/16”, “1854/16” combined high yields (11.10–11.31 t/ha) with high value of SDS-sedimentation (62–65 ml). The breeding material identified during the research was used for further study and has been involved in hybridization to increase productivity and grain quality. |
