Elements of productivity and economically valuable traits of spring barley in light chestnut soils of the North-Western Caspian region

Abstract

The article presents collectible varieties of spring barley of different ecological and geographical origin, their productivity elements are studied and optimal economically valuable signs are determined in the conditions of light chestnut soils of the Lower Volga region.

Introduction. Scientific research and data analysis were conducted at the Caspian Agricultural Research Center of the Astrakhan region. In order to identify valuable introduced varieties of spring barley with optimal indicators of economically valuable characteristics and high adaptive capabilities to the conditions of the arid climate of the Northwestern Caspian region.

Materials and methods of research. The experience was based on the methodology of B. A. Dospekhov. The breeding work in the experiment was carried out according to the "Methodological guidelines for the study and preservation of the world collection of barley and oats". The predecessor is an early steam.

Results and conclusions. As a result of the study of introduced varieties of spring barley, the most productive samples with high economically valuable characteristics were identified. By the number of productive stems – Pervotselinnik, Gutter, Vladimir; by the length of the ear – T-12, Yuzhny, Dneprovsky 103; by the number of grains – Dneprovsky 103, Etiquette, Pervotselinnik, Gutter, Yuzhny and Nutans 108; by the weight of grain from the ear – Pervotselinnik, Gift of Siberia, Wanderer; by the weight of 1000 seeds and yields – Pervotselinnik, Gift of Siberia, Vladimir, Ataman, Maritime, Sloop sa, Gutter, Wanderer, Mamluk, Magutny.
