Yield and fat content in oil flax seeds under the conditions of the Northern Trans-Urals

Abstract

Oil flax is a valuable agricultural crop that is widely used in industry. Technical oil and cheap vegetable protein for livestock production are obtained from it, which makes it a valuable feed crop for the production of oilcake and presscake. The purpose of the work was to study collection samples of oil fl ax in the forest-steppe zone of the Northern Trans-Urals, to identify the best in terms of yield and fat content. It was revealed as a result of the research that some samples of oilseed fl ax from the world collection of All-Russian Institute of Plant Growing have high adaptability to the conditions of the forest-steppe zone of the Northern Trans-Urals. These samples are characterized by high yield, as well as a high amount of oil in the seeds. Thus, the use of these samples in breeding work will make it possible to create new varieties of oil fl ax that meet modern production requirements. As a result of the research, Russian varieties were identifi ed that were distinguished by high productivity such as Voronezhsky 1308/138, VIR 1650, Sibirsky 397, and August. Some varieties of imported selection such as Micael (France), Omega amd Prairie Blue (Canada), Chibik (Chibis, Ukraine) and BaYaNo 7 (China), their yield varied at the level of 210–247 g/m2. The highest fat content in seeds was in the following varieties: BaYaNo 12 and BaYaNo 7 (China) – 50,7 and 47,5 %, August (Russia) – 47,5 %, Bakhmalsky 1056 (Uzbekistan) – 47,6 %. The selected varieties are recommended for use in practical selection and production on the soils of the Northern Trans-Urals region.
