Evaluation of variety samples of carriable caustic by economically valuable signs and properties in forest steppe of Samara Volga region

The article presents the results of a study of collection samples of boneless rind according to the most important quantitative characteristics (plant height, foliage, plant productivity by green mass, seed productivity, qualitative indicators of vegetative mass). The object of study was breeding material created in local conditions, obtained from other research institutions, as well as isolated wild-growing forms. It was established that the yield of green mass during the years of study was characterized by significant variability (V = 24.6-23.06%) and ranged from 14.3 to 30.3 t / ha. On average for 2018-2019. the largest increase to the standard was provided by selection from the wild-growing population of Selection 1 and the variety Vegur, 11.4% and 13.9%, respectively. Erkeeni samples (16.39%) and Selection 2 (15.88%) differed in the high protein content, exceeding the standard 2.3-2.8%. Over the years of study, the maximum seed yield was provided by selections from the local wild-growing populations of Selection 2, Selection 1 and SibNIIISHKhoz 189, the excess over the standard was 19.0 - 33.3%. The selected samples have a set of economically valuable traits and can be used as starting material for the creation of new varieties of boneless rump in the forest-steppe of the Samara Trans-Volga region.
