To use flax oil in food, it is necessary to decrease the content of linolenic acid. We developed the oil flax variety Amber by individual selection from the hybrid population of the 3rd generation from crossing of the low-linolenic variety Linol and the breeding line 34725. The variety is mid-ripening, the duration of its growth season is 90-98 days, it is well adapted to the soil and climatic conditions of Siberia. It differs from the standard variety by its low content of linolenic acid in oil – 4.8-6.3 %. According to the results of competitive variety testing in 2016-2018, the variety Amber exceeded the standard variety Severny in terms of seed productivity by 0.29 t/ha. The variety ripens in uniformity, it is resistant to Fusarium blight, lodging and shedding, it is suitable for mechanized harvesting, it is developed to obtain edible oil of high quality. The potential cultivation areas of the oil flax variety are Volgo-Vyatsky region, Ural and West Siberia.

In 2016-2018 in the competitive variety testing there was conducted the study of peas on the fields of research crop rotation of the laboratory of legumes breeding and seed-growing of the FSBSI “ARC “Donskoy” located in the zone of unstable humidity of the Rostov region (Zernograd district). The analysis of the obtained seeds was carried out in the laboratory of biochemical estimation of breeding material and grain quality of the FSBSI “ARC “Donskoy”. The objects of research were new pea lines of breeding of the FSBSI “ARC “Donskoy”, which differed in their morphological, biological and economically valuable traits and properties. During the years of research, the meteorological conditions of the vegetation period of peas were contrasting, which made it possible to objectively estimate the lines in the climatic conditions. In the competitive variety testing for the period of 2016-2018, the evaluation of new promising pea lines due to their productivity and protein percentage resulted in identification the leafless pea lines “G-1002” and “G-1003” which exceeded the standard variety “Aksaisky Usaty 5” in productivity (0.30 and 0.39 t/ha) and protein yield (0.08 and 0.10 t/ha, respectively). There is a high correlation between seed productivity and protein content (0.95). There is a low correlation between protein percentage in seeds and protein yield (0.35). There is no correlation between productivity and protein percentage in seeds (0.03). The analysis of correlations shows that pea breeding on productivity directly affects on protein yield, i. e. the larger seed productivity, the larger protein percentage. The most productive pea lines are going to be used in further breeding work.

The main parameter of the breeding work with alfalfa in the ARC “Donskoy” is the improvement of fodder and seed productivity. Through the years the breeding work was carried out with 500–860 collection samples of alfalfa, alfalfa hybrids and alfalfa lines of the local origin. The main method of the breeding work was poly-crossing. It’s characterized with a multiple repetition of selections of the best plants from the populations, their self-pollination and crossing by free pollination in the plots of poly-crossing. It resulted in accumulation and concentration of favourable traits in the population. The selection promoted systematic improvement of synthetic populations according to economic-valuable traits, especially fodder and seed productivity. During the research, productivity of green mass of the standard variety ‘Rostovskaya 90’ was 28.2 t/ha in the first cutting and 19.0 t/ha in the second one on average. The varieties ‘Lyutsiya’ and ‘Selaynka’ produced 30.6 t/ha, 19.8 t/ha and 32.1 t/ha, 20.4 t/ha respectively. The sum of the harvested green mass of the standard variety was 47.2 t/ha, while ‘Lyutsiya’ produced 50.5 t/ha and ‘Selaynka’ 53.1 t/ha, that is on 7.0% and 12.5% larger than the standard. The similar result was obtained in productivity of dry matter. The total quantity of dry matter produced by the standard variety was 11.6 t/ha (two cuttings), the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 12.6 t/ha and 12.8 t/ha that is on 8.6% and 10.3% more than the standard. The estimation of the breeding work with alfalfa in the preliminary and competitive variety testing allowed to identify the new alfalfa variety ‘Golubka’ and to send it to the State Variety Testing. In the competitive variety testing (2012–2016) the variety produced larger yields that the standard variety (productivity of all five 1-st cutting). With its average productivity of green mass (31.9 t/ha) it exceeded the standard on 13.1%. In the 2-d cutting its green mass productivity was 20.9 t/ha that is on 10.9% more that the standard.  With the average productivity of green mass the variety ‘Golubka’ produced 8.0 t/ha in the 1-st cutting and 4.9 t/ha in the 2-d, that is on 12.7% and 8.9% lager that that of the standard.  The variety ‘Golubka’ produced 52.8 t/ha green mass for two cuttings and 12.8 t/ha dry matter that is on 11.9% and 10.3% larger than the standard variety ‘Rostovskaya 90’. Seed productivity of the standard variety was 0.23 t/ha on average, the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 0.25 t/ha, the new variety ‘Golubka’ produced 0.29 t/ha, that is on 8.7 and on 26.1% more than the standard.

AbstractIt may be desirable to increase the level of conjugated linoleic acid (CLA) in milk as a health benefit in human nutrition. The purpose of this work was to separate the effects of linoleic and linolenic acids on CLA production in dairy cows and to determine to what extent endogenous synthesis contributes to cis-9, trans-11 CLA concentration in milk fat. Eight lactating cows and four non-lactating duodenal fistulated cows were used in a 4 ✕ 4 Latin-square design. All cows received a basal diet of grass silage that was supplemented with one of four concentrates, which were designed to differ in their linoleic and linolenic acid contents. The oil components of the concentrates were produced from mixtures of olive, linseed, rape, soya and sunflower oils to produce the four treatments: low linoleic/ low linolenic acid (LL), low linoleic/high linolenic acid (LH), high linoleic/low linolenic acid (HL) and high linoleic/ high linolenic acid (HH). Milk cis-9, trans-11 CLA contents were 0·8, 0·9, 0·9 and 1·1 g/100 g fatty acid methyl esters (P < 0·05) and yields were 5, 7, 7 and 8 g/day (P < 0·05) for the LL, LH, HL and HH treatments, respectively. The yields of trans-C18:1 fatty acids in milk were 19, 22, 21 and 23 g/day (P < 0·05), respectively. Taking the data for the cis-9, trans-11 CLA content and flow of duodenal fluid from the fistulated cows and representing this in terms of dietary intake by the lactating animals, the amounts of cis-9, trans-11 CLA produced in the rumen were calculated to be 0·8, 0·9, 1·2 and 1·1 g/day (P < 0·05) and for trans-C18:1 fatty acids 58, 58, 66 and 69 g/day (P < 0·05). Increasing linoleic and/or linolenic acids in the diet can increase the cis-9, trans-11 CLA content of cows’ milk. Only diets high in linoleic acid increased cis-9, trans-11 CLA production in the rumen. On all four diets, more than 80% of cis-9, trans-11 CLA in milk was produced endogenously by Δ9-desaturase from trans-11 C18:1 in the mammary gland. Cows on the same diet have different milk fat cis-9, trans-11 CLA concentrations that may be partially explained by differences in Δ9-desaturase activity between cows. Increasing the activity of Δ9-desaturase in the mammary gland may offer greater potential for enhancing the cis-9, trans-11 CLA content of milk fat than increasing cis-9, trans-11 CLA production in the rumen.

The narrow-leafed lupin (Lupinus angustifolius L.) is a valuable legumes crop used as forage and green manure which is adapted to wide spectrum of soil-and climatic conditions; the crop has short domestication history. The protein content in its seeds and in dry matter of green mass varies from 30.0 to 37.0% and from 16.0 to 22.0 % respectively and depends on ecotype and soil-and-climatic conditions. This lupin specie can accumulate to 300 kg/ha symbiotic nitrogen in biomass and assimilates phosphorus and potassium of heavy available soil layers. It is very technological suitable for common used machinery systems. The State List of breeding achievements of Russia recommends the following regions for lupin cultivation: the North, the North-West, the Central, the Volga-Vyatka, the Middle-Volga, the Central Chernozem, the Ural, the West Siberia and the East Siberia. The tests were carried out in 2017-2020 in the All-Russian Lupin Scientific Research Institute which is located in the South-West of the Central region. Ten varieties and breeding lines bred in the Institute are tested. The samples differ by early ripeness and anthracnose tolerance. The average experimental variety grain yield was 2.38 t/ha. The vars. Uzkolistny 53-02, USN 53-236, Bryanskiy kormovoy and SBS 56-15 have the highest yield and adaptivity (103-113 %). The index of year conditions was revealed; 2017 with the index 0.56 was the most favorable for implementation of grain productivity of the tested narrow-leafed lupin varieties. In the ecological varieties testing the soil-and-climatic conditions of Shatilovskaya experimental station (Orel region) were the most favorable for implementation of variety grain productivity (4.0-4.5 t/ha). Grain yield was 3.0-4.0 t/ha in ecological locations which differ in soil-and-climatic conditions: there are Kaliningrad region, Mordovia Republic, Krasnoyarsk region etc.
