Features of the winter bread wheat varieties of unified type developed by the Agricultural Research Center “Donskoy”

Abstract

The current paper has presented the characteristics of the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy”. Winter wheat is the most valuable grain food crop grown in vast areas. Breeding plays an important role in increasing production volume and improving grain quality as the basis of the country’s food fund. Expanding grain crops area, among which wheat predominates, there is a problem of crop rotation. Therefore, the development of unified varieties capable of producing stable high grain yields after various forecrops is one of the most urgent areas of breeding work for winter bread wheat. The purpose of the current study was to characterize the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy” according to the main economically valuable traits. Due to the intensive breeding work over the past decade, on the basis of some of the best zoned varieties ‘Ermak’, ‘Stanichnaya’, ‘Donskoy syurpriz’ there was developed a number of new promising genotypes, which are already being used in production sowings of winter wheat in the Rostov region and other regions of our country. The new winter bread wheat varieties of unified type ‘Lydia’, ‘Kapitan’, ‘Lilit’, ‘Krasa Dona’, ‘Volnitsa’, ‘Volny Don’, ‘Zhavoronok’ and ‘Polina’ are more productive than their parental forms. In combination with grain of high quality, resistance to bio and abiotic environmental factors, they are very valuable, beneficial for cultivation and improvement of the production of commercial wheat grain of high quality.
