Abstract
Wheat yield increase and grain quality indicators improvement is one of the primary tasks for the agro-industrial complex. The purpose of the current study was twofold: estimate the productivity and grain quality indicators of winter bread wheat varieties; identify the most valuable ones for further use in breeding programs. The surveys were carried out on the experimental field of SSE “Agricultural Research Center «Donskoy»” in 2018-2020. In the study area, the average annual precipitation was 582.4 mm, the average annual temperature – 9.7 °C. The object of the study – 23 winter bread wheat varieties of semi-intensive type developed in the ARC “Donskoy”. Variety ‘Don 107’ was used as a standard one. Forecrop – maize for grain. Winter wheat was planted at the optimum planting dates; seed placement depth – 4-6 cm. The experiment was replicated six times; The plot area – 10 m2. Varieties ‘Lilit’ (6.8 t/ha), ‘Polina’ (6.8 t/ha), ‘Zolotoy Kolos’ (6.8 t/ha), ‘Lidiya’ (6.9 t/ha), ‘Premyera’ (6.9 t/ha), ‘Volnitsa’ (7.0 t/ha), ‘Volny Don’ (7.0 t/ha), ‘Ayuta’ (7.2 t/ha) exceeded standard variety ‘Don 107’ by 0.4–0.8 t/ha. All varieties studied in the trial corresponded to the standards of the 1st class in terms of hectolitre weight (not less than 750 g/l) and vitreousness (not less than 60.0 %). The largest grain was formed by varieties ‘Zhavoronok’ (43.4 g), ‘Donskoy surpriz’ (43.6 g), ‘Ayuta’ (44.6 g), ‘Volnitsa’ (44.9 g), ‘Premyera’ (48.2 g). The largest values of protein in grain (13.1–13.4 %) were identified in varieties ‘Lidiya’, ‘Stanichnaya’ and ‘Podarok Krymu’. Varieties ‘Asket’ and ‘Podarok Krymu’ produced grain with the largest gluten content (28.6 % and 28.9 %, respectively). The results of two-way analysis of variance have proved the greater influence of the factor “year” on productivity (64.0 %), protein (72.0 %) and gluten (70.0 %) content in grain of winter bread wheat than that of the factor “genotype” and their correlation.
