The productivity of collection samples of oil flax in northern forest-steppe of Tyumen region

The research presents the results of the study of oil flax samples from the collection of the Federal Research Center “All-Russia Institute of Plant Genetic Resources named after V.I. Vavilov " in the conditions of northern forest-steppe of Tyumen Region on experimental field of the FSBEI HE" State Agrarian University of the Northern Trans-Urals". The soil of experimental field was leached chernozem, the predecessor was annual grasses. The number of studied samples was 31. The collection was sown on the plots with an area of 1 m2 using an SSFK-10 seeder, harvesting was done manually. The observations and calculations in the experiment were carried out according to the recommendations of the Federal Research Center “All-Russia Institute of Plant Genetic Resources named after N.I. Vavilov ". The protein content in seeds was determined by Kyeldal method (State standard specification 10846-91), the fat content was determined with the help AMB-1006M NMR analyzer. The highest seed yield (240-270 g/m2) was formed by the samples: Voronezh 1308/138 (k-5579) from Russia, Micael (k-8218) from France, Omega (k-8606) and Prairie Blue (k-8609) from Canada, Chibik (k-8710) from the Ukraine. It should also be noted that a number of domestic specimens, which exceeded the average value of the collection by 8-12 %: VIR 1650 (k-5831), Isilkulsky (k-7481), Istok (k-8677) and August (k-8799). According to the oil content of seeds, the following samples were distinguished: Ba Ya No. 12 (k-8729) and Baya No. 7 (k-8815) from China, Trickle (k-964) from Russia, Bakhmal 1056 (k-6056) from Uzbekistan. The oil content of seeds in these samples made 46.9-50.9 %. The samples were characterized by high protein content in seeds (24.6-25.0%): Rucheek (k-7964) from Russia, Micael (k-8218) and Oliver (k-8220) from France, Eureka (k-8711) from the Ukraine. For practical selection, the most promising could be the samples with increased productivity and high quality of seeds: Voronezhsky 1308/138 (k-5579) and Rucheek (k-7964) from Russia, Ba Ya No. 12 (k-8729) from China, Micael (k-8218) and Oliver (k-8220) from France, Omega (k-8606) and Prairie Blue (k-8609) from Canada.
