Purpose. To evaluate the varieties: ‘MIP Assol’, ‘Balada Myronivska’, ‘Hratsiia Myronivska’, ‘MIP Yuvileina’, ‘MIP Lada’, ‘MIP Dniprianka’ and the standard variety ‘Podolianka’ and promising breeding lines: ‘Erythrospermum 55023’, ‘Lutescens 22198’, ‘Lutescens 37519’, ‘Lutescens 60049’, ‘Lutescens 60107’ winter wheat of the Mironovka`s breeding according to grain quality indicators.
Methods. The research was conducted during the 2019–2021 in the breeding crop rotation of the winter wheat breeding laboratory of the V. M. Remeslo Myronivka Institute of Wheat, NAАS of Ukraine. The main method of research was laboratory and field, supplemented by analytical studies, measurements, calculations and observations.
Results. The following breeding lines were the best in terms of protein content during the first sowing period: ‘Erythrospermum 55023’ (11.9%), ‘Lutescens 55198’ (12.8%), ‘Lutescens 37519’ (11.7%) and ‘Lutescens 60107’ (10.7%). During the second sowing period, the best varieties and breeding lines turned out to be ‘Hratsiia Myronivska’ (11.4%), ‘MIP Dniprianka’ (12.3%), ‘Erythrospermum 55023’ (12.3 %), ‘Lutescens 55198’ (11.4%), ‘Lutescens 37519’ (12.3%) and ‘Lutescens 60049’ (12.8%). According to the grain vitrification index during the first sowing period, the following can be distinguished: ‘Balada Myronivska’ (86.7%), ‘MIP Lada’ (89.3%), ‘MIP Dniprianka’ (87.3%), ‘Erythrospermum 55023’ (86.3 %), ‘Lutescens 55198’ (94.3 %) and ‘Lutescens 37519’ (91.0 %). During the second sowing period, these were ‘Balada Myronivska’ (86.7%), ‘Hratsiia Myronivska’ (79.3%), ‘MIP Lada’ (85.0%), ‘MIP Dniprianka’ (81.7%) and breeding lines ‘Lutescens 55198’ (80.7%) and ‘Lutescens 60049’ (81.3%). According to the content of raw gluten, the variety ‘Hratsiia Myronivska’ (26.2%) was selected. For all studied breeding lines, the value of the crude gluten content indicator varied from 26.0% to 29.9%. During the second sowing period, a higher percentage of raw gluten content was noted in the varieties ‘Hratsiia Myronivska’ (29.9%) and ‘MIP Dniprianka’ (27.4%) and selection lines – ‘Erythrospermum 55023’ (28.4%), ‘Lutescens 55198’ (27.4%), ‘Lutescens 37519’ (27.1%) and ‘Lutescens 60049’ (29.1%).
Conclusions. During the three years of observations, the weather conditions differed in the amount of precipitation and the sum of active temperatures both during the growing season and during the period of flowering and maturation, which significantly affected the results of the analysis of grain quality indicators of winter wheat varieties and promising lines. Having analyzed the obtained results, it is possible to single out the varieties ‘Hratsiia Myronivska’ and ‘MIP Dniprianka’, as well as the breeding lines: ‘Erythrospermum 55023’, ‘Lutescens 55198’, ‘Lutescens 37519’ and ‘Lutescens 60049’, which exceeded the standard variety ‘Podolianka’ and the average experimental values for such basic indicators as protein content, gluten content, vitreousness and 1000-seed weight.
