Comparative estimation of winter bread wheat varieties in an inter-station trials due to their quality indicators
Abstract
There has been conducted a comparative estimation of winter bread wheat varieties in an inter-station trials due to quality indicators of kernels and flour. Modern breeding is the process of developing new genotypes that combine the maximum number of breeding traits. The necessity to obtain such varieties predetermines the wide introduction of genetically diverse well-studied samples into the process of hybridization. The success of breeding for these traits is determined by the availability of valuable initial material, timely and effective estimation of quality indicators at all stages of the breeding process. The purpose of the study is to identify genetic sources of high quality grain and flour of winter bread wheat. The trials were carried out in the FSBSI “Agricultural Research Center “Donskoy” in 2015-2017. The objects for the study were 80 winter bread wheat varieties of domestic and foreign development. The study of the varieties on a set of quality indicators of kernels and flour (protein and gluten percentage, SDS-sedimentation, flour strength, volume output bread, general baking estimation) has identified 14 winter bread wheat varieties “Nakhodka”, “Aksiniya”, “Volnitsa”, “Tanais”, “Asket”, “Zhavoronok”, “Donskaya yubileynaya”, “Donskaya bezostaya”, “Lidiya”, “Rostovchanka 7” (FSBSI “ARC “Donskoy”), “Proza”, “Poema” (FSBSI Verkhnevolzhsky FARC), “Antonina”, “Irishka” (FSBSI RCG named after P. P. Lukyanenko).Breeding plays an important role in solving the problem of improving the winter bread wheat quality. Therefore, to create new high-quality genotypes of a given crop, there has been proposed to use the varieties identified during these studies as genetic sources.
