Abstract

The current paper has presented the analysis of the structure of sown areas under winter bread wheat in the Voronezh region in 2016–2018, and there has been established a recent increase the share of the varieties lutescens L. In order to substantiate the present tendency, there have been also used the study results of the varietal set of the Eryshevsky State Varietal Plot of the Voronezh region. The field trials on the Plot to study winter bread wheat productivity were carried out according to the Method of the State Variety Testing for Agricultural Crops (1989), grain quality was estimated by the methods described in the reference book “Grain quality estimation” (1987), and according to the recommendations for the corresponding devices. The data on varietal sowings of winter wheat was provided by the Department of Agricultural Policy of the Voronezh Region. According to the study results, there have been shown the main originators on the market of varieties in the winter bread wheat sowings, as well as in the State Variety Testing.

In the State Variety Testing there has been noted a significant increase in wheat varieties from foreign farms and varieties of lutescens. According to the study results, when averaging the obtained productivity data and grain quality indicators at the the Eryshevsky State Varietal Plot, there hasn’t been found any significant difference between winter bread wheat varieties of the lutescens and erythrospermum varieties. There has been given average data on productivity and grain quality of varieties obtained from various originators.
