In this study, oat bran and blackberry were used separately and together in the production of probiotic yogurt (Lactobacillus acidophilus). It was aimed to determine the effect of oat bran and/or blackberry on probiotic viability, total phenolic content and antioxidant activity levels (DPPH, ABTS, CUPRAC methods) of yoghurts during both cold storage times and in vitro gastrointestinal digestion stages. At the end of the 21 day of storage period, it was determined that the highest and lowest L. acidophilus viability was found in yoghurt containing blackberry (B) (107 cfu/g) and oat bran (Y) (105 cfu/g), respectively. Oat bran and blackberry containing yogurt YB and control yogurt had the highest and lowest total phenolic content at the beginning and end of the storage period, respectively. According to the antioxidant activity results determined by the DPPH method, B yogurt had the highest antioxidant activity, while according to the ABTS and CUPRAC methods, YB yogurt had the highest antioxidant activity. As a result, it has been revealed that the functional properties of probiotic yogurt can be further improved with the addition of oat bran and blackberry, and blackberry can have a prebiotic effect on L. acidophilus.

Oat is an important cereal used as human food, animal feed and medicinal plant. This study was conducted to determined yield and some physical quality characteristics of 22 oat genotypes in Turkey in rainfall and supplemented irrigation conditions during 2016-2017 growing season at Yozgat/Yerköy, Turkey. Experiments were carried out in randomized complete block design with three replications. In the trials, plant height, panicle length, grain yield, biological yield, thousand grain weight, hectoliter weight and groat percentage were investigated. İn non-irrigated conditions, plant height, panicle length, grain yield, biological yield, thousand grain weight, hectolitre weight and groat percentage were between 54.2-86.2 cm, 14.1-23.3 cm, 116.9-288.1 kg da-1, 593.1-938.9 kg da-1, 24.1- 38.5 g, 40.4-48.4 kg and 63.5-73.6% whereas in supplemented irrigation conditions, plant height, panicle length, grain yield, biological yield, thousand grain weight, hectolitre weight and groat percentage were 65.0-98.7 cm, 15.3-25.7 cm, 226.1-439.6 kg da-1, 979.2-1381.9 kg da-1, 24.2-39.3 g, 43.5-51.0 kg and 62.5-73.0%, respectively. Supplemented irrigation application increased both grain yield and biological yield approximately 1.5 times compared to application based on rainfall. Genotypes G9, G10, G12, G13, G14, G17, G18, G21 and G22 had the highest grain yield in experiments irrigated with both rainfall and supplemented irrigation.

This study was carried out in 2015-2016 cropping year in Kırklareli ve Edirne locations with 60 oat lines and 4 varieties of commercials (Kırklar, Kahraman, Yeniçeri and Sebat). The experiment was arranged in an alpha lattice experiment design (8 x 8= 64) with three replications. In the research, it was aimed to determine genotypes suitable for the region by examining yield and some quality parameter performances of oat genotypes.The traits such as grain yield (GY), thousand kernel weight (TKW), test weight (TW), plumpness (P, sieved 2.2 mm slotted), husk rate (HR), full grain oat protein (FGOP), starch (S), β-glucan (β-G) and L value (L) content of genotypes were investigated. The variation among oat lines for grain yield was significant and differences for TKW, TW, P, HR, FGOP, S, β-G, and LBV were also determined. The GY, TKW, TW, P, HR, FGOP, S, β-G and LBV of oat lines ranged between 588.3-860.8 (735.0) kg/da, 21.1-44.0 (31.9) g, 49.3-58.9 (54.7) kg/hl, 13.5-93.5 (69.9) %, 12.1-31.1 (23.9) %, 14.9-20.9 (18.1) %, 51.3-60.5 (56.2) %, 3.2-4.7 (4.0) % and 83.6-89.3 (87.1) in Kırklareli and 472.8-90.35 (681.3) kg/da, 23.0-41.3 (32.4) g, 42.9-55.3 (549.2) kg/hl, 22.4-95.8 (74.7) %, 18.3-30.8 (25.0) %, 14.9-20.3 (18.1) %, 53.1-62.8 (57.5) %, 2.9-5.0 (3.9) % and 84.2-89.9 (87.7) in Edirne respectively.The oat lines 14, 16, 19, 43, 3, 48 and Kırklar and Kahraman varieties were hopeful in Kırklareli and the oat lines 16,18,19, 21, 22, 44, 2, 51, 52 and Kahraman variety were hopeful in Edirne location for grain yield and investigated quality parameters. The oat lines 14, 16, 19, 21 and Kahraman variety were suitable in terms of investigated traits in Trakya-Marmara region.

This study was conducted to collect, preserve and identify local oat genotypes grown in the Central and Western Black Sea region. Within the scope of the research, 251 local oat genotypes were collected from the places where they were cultivated in Düzce, Bolu, Zonguldak, Karabük, Kastamonu, Ordu, Sinop, Samsun, Amasya and Tokat provinces. The collected genotypes together with 4 standard oat varieties were taken into field trial in Ondokuz Mayıs University Faculty of Agriculture Research and Application field according to Augmented trial design in 2008 and 2009 growing seasons. As a result of the study, it was found that there were significant variations in terms of the parameters examined. Among the genotypes, the growth pattern of the 229 genotypes was perpendicular, The cluster genotypes of 163 genotypes were scattered, 132 genotypes were yellow in color, 157 genotypes were strongly stringy and 154 genotypes had callus hairiness. When the Matrix table was examined, it was found that the local genotypes with semi-horizontal growth pattern were not found in Amasya, Karabük, Kastamonu, Samsun and Tokat locations. In particular, parameters such as growth type, cluster type, color of husk, awn condition and callus hairiness. it provides ease of identification, since it does not affect the environmental conditions. In the light of this information, it is thought that the genetic variation is high in terms of ecology in which local genotypes are collected and will be beneficial for the protection of our genetic resources and for the future of national agriculture.

In this study 384 Turkish originated oat genotypes obtained from different gene banks, were characterized and evaluated for agronomical traits with four commercial cultivars (Checota, Sebat, Faikbey and Seydişehir) under augmented experiment design for 2012-2013 and 2013-2014 cropping years. Oat landraces were evaluated for stem diameter (SD), plant height (PH), panicle length (PL), vegetative period (VP), grain filling period (GFP), days to maturity (DM), grain number per panicle (GNP), grain weight per panicle (GWP), thousand kernel weight (TKW), lodging (LOD), barley yellow dwarf virus (BYDV) and single row yield (SRY) under Kahramanmaraş conditions. According to the results of field trail for two years, differences of genotypes were significant for SD, PH, PL, VP, DM, TKW and SRY. However, the components such as SD, PL, VP, GFP, DM, GNP, GWP, TKW and SRY were significantly changed for the years and year x genotype interactions were also significant for PL, VP, DM, TKW and SRY. The landraces performed better than the commercial ones for the most of the evaluated traits. The SRW ranged between 4.65 g (TL444) to 202.1 g (TL614). Moreover, the other genotypes with the higher SRY were TL708, TL714, TL734 and TL703 genotypes with 167.85, 160.25, 153.90 and 149.7 g SRY, respectively.

Nowadays usage of dietary fibers in foods has been increasing duo to revealing of health benefits. Beta-glucans found especially in oats and barley, are polysaccharide and source of water-soluble dietary fiber. Positive effects of beta-glucans like healing coronary-heart disease, lowering blood cholesterol level, balancing blood sugar level and preventing obesity, made beta-glucans widespread functional food components for producing various foods. In addition to beneficial physiological effects of beta-glucans, they texturize, gelatinize, emulsify and stabilize the foods. They increase viscosity, replace fat and enhance rheological properties in cereal, meat and dairy products. They are also used to produce packing material depending on their mechanical properties and molecular weights. In this review, effects of addition of cereal based beta-glucans on technological and functional properties of various foods are revealed based on previous studies.
