The results of studies of economically valuable traits of various varieties and new lines of winter wheat are presented. The studies were carried out on the experimental field of the Saratov State Agrarian University, located in the Lower Volga region with a sharply continental climate on dark chestnut soil. A study of the collection of varieties and lines of winter soft wheat made it possible to identify samples that are most suitable for economically valuable traits in the arid conditions of the Lower Volga Region and are highly adaptable. The largest grain yield was formed by the line  SP-108 (4.54 t / ha) and such varieties as Levoberezhnaya 3  (4.28 t / ha), Stanichnaya (4.19 t / ha), Gubernya (4.11 t / ha), Agra (4.04 t / ha), and Novoershovskaya (4.03 t / ha). Most of these varieties and lines were created by scientists from local breeding centers (Research Institute of Agriculture for  the South-East Region,  the Ershov Experimental Station and the Saratov State Agrarian University). The high content of raw gluten in the grain was revealed in the varieties: Levoberezhnaya 3 (35.3%), Aelita (34.7%), Patriarch (34.6%), Dzhangal (34.3%), Lutescens 72 (34.3% ), Zernogradka 9 (34.2%), Yunona (33.8%), Yesaul (33.7%); lines SP-137 (33.7%) and SP-110 (34.9%). The best indicators of IDK were found in such varieties as Levoberezhnaya 3 (67.8 units), Dzhangal (69.4 units), Aelita (73.7 units), lines SP-137 (69.0 units) and SP-110 (71.2 units). The noted varieties and lines of winter wheat are recommended for further breeding in the direction of increasing drought tolerance, adaptability and productivity of the crop in the arid zone of the Lower Volga Region. The SP-108 line (SGAU 11/2019) allocated for high productivity potential was transferred to the state variety test under the name Elegya (Stepnaya 19).

The article presents the results of three years of field research on studying of influence of ways of the basic processing of soil and systems of applied fertilizers on productivity of grain crops. The experiment considered winter wheat, cultivated on black steam, and is itself a precursor to the Sudanese grass. Three variants of the main tillage and four variants of the use of mineral fertilizers in the cultivation of winter wheat varieties of local selection of reed 3 were studied. Field experiments were conducted at the STC of Volgograd state University "Gornaya Polyana" on light chestnut soils from 2016 to 2019. As a result of studying the productivity of winter wheat in rainfed conditions on light chestnut soils of the Lower Volga region, it was found that the maximum values of biometric indicators, elements of the structure of the crop, biological and economic productivity were obtained during its cultivation by deep chisel processing by the working bodies of the "Ranch" with the use of ammophos and potassium chloride during sowing and early spring feeding with ammonium nitrate. The minimum values of biometric indicators, elements of the structure of the crop, biological and economic productivity are obtained by cultivating it on a small disk processing without the use of fertilizers.

In a competitive variety trial, promising selection lines of sugar sorghum were studied in the Lower Volga region. Based on a set of signs, the best lines were identified, which are recommended for transfer to the State Variety Testing. Breeding lines, which are distinguished by high values of commercially valuable traits, can be used in planned crosses to create highly productive varieties and hybrids of sugar sorghum.
