STARTING MATERIAL FOR THE CREATION OF EARLY RIPENING SOYBEAN VARIETIES
2018
Nekrasov, A. Yu.
Due to protein deficiency in human and animal diets, soy can serve as a solution to this problem. In the conditions of continuing economic sanctions for restoration of their own elite seed production, it is necessary to pay great attention to the development of their own selection. One of the factors that can be the creation of new highly productive varieties of soy. With the aim of speeding up the selection process, it is proposed to use the already identified sources and donors of the main economically valuable features. On the basis of VIR and its stations, a study of soybean samples on important economically useful traits was carried out. The study was conducted according to the VIR method. Recently, breeders have shown great interest in a group of early maturing specimens. Therefore, the emphasis of this article is put on early maturity and the results of studies of this group of ripeness from the world soya collection are presented. When examining samples according to the main feature of selection for yield, specimens with catalog numbers-1259; 11309; 11,246; 11,245; 11313; 11412; 11262; 11311; 11038; 11,254; with introductory numbers - 0143326; 6,128,223; 0144137. On the basis of productivity from a single plant, it should be noted samples with catalog numbers: 11363; 11295; 11302; 11313; 11,254; 11,245; 11261; with the introductory number of 618010. On the basis of the size of the seeds, the following samples showing the maximum mass of 1000 seeds for this ripening group can be cited: 11400; 11414; 11,396; 11,395; 11,397; 11294; 11485; with introductory numbers-621986; 619,760; 618010. On the height of the attachment of the lower bean, it is necessary to note the samples showing the maximum height of this feature: 11412; 11411; 11254.
