Grain Yield and Some Quality Traits of Different Oat (Avena sativa L.) Genotypes
— Oat cultivars should have both high yield potential and some quality criteria in accordance with using targets. Hence, grain yield and some quality traits of 25 oat genotypes grown in two consecutive years were studied. This study was carried out during the 2012–2013 and 2013–2014 growing seasons in Yozgat, Turkey. Grain yield, plant height, hectolitre weight, thousand grain weight, great percentage and grain composition (protein, fat, ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), β-glucan and starch) were evaluated. Analysis of the combined data for two years showed significant genotypic differences for all traits. According to the average of two years, among the genotypes, grain yield varied from 2432.3 (2 numbered genotype) to 5650.2 (19 numbered genotype) kg ha-1 , plant height from 76.3 to 128.3 cm, hectoliter weight from 41.5 to 52.3 kg, thousand grain weight from 24.5 to 41.3 g, groat percentage from 70.4 to 76.6 %, protein content from 11.1to 14.3 %, fat content from 5.86 to 8.47 %, ash ratio from 2.52 to 3.43 %, ADF content from 11.0 to 16.4 %, NDF content from 29.5 to 37.3 %, β-glucan content from 1.33 to 2.58 % and starch content ranged from 34.9 to 47.7 %. Grain yield was significantly and positively correlated with thousand grain weight (r = 0.253**) and neutral detergent fibre (r = 0.160**). However, correlations between grain yield with crude protein (r =-0.216**) and hectolitre weight (r = 0.246) were significantly and negative.

The objectives of the study were to investigate the variability of oat (Avena sativa L.) grain physical traits and chemical composition and to determine relationships between traits. Field experiments including five hulled oat genotypes were carried out at the State Stende Cereal Breeding Institute for two seasons during 2010-2011. Variation of traits was mainly determined by genotype (w 2 = 53 -88%), with the min/max values for 1000 kernel weight 32.4/36.5 g, test weight 470.0/507.9 g·L -1 , hull content 215.4/265.6 g·kg -1 , crude protein 110.0/124.9 g·kg -1 , starch 456.9/483.0 g·kg -1 , b-glucans 28.1/36.6 g·kg -1 and crude fat 46.2/60.0 g·kg -1 . Oat variety 'Arta' had the highest test weight (507 g·L -1 ) and contents of crude protein (124.9 g·kg -1 ), b-glucans (36.5 g·kg -1 ), a-tocopherol (7.8 mg·kg -1 ), average crude fat (55.5 g·kg -1 ) and total phenolics (113.9 mg gallic acid equivalents/GAE 100 g -1 DM) in the grain. Expression of traits significantly depended on meteorological conditions in the specific year. In both years of investigation there were significant (p < 0.05) positive correlations between contents of b-glucans and crude fat, and negative correlation of b-glucans with starch content, total phenolics and antiradical scavenging activity.
Beta-glucan and Grain protein studies of oats (Avena sativa L.) under temperate conditions
Electronic Journal of Plant Breeding, 2015
The experimental material comprised of ten oats (Avena sativa L.) genotypes and their 45 F1 crosses evaluated for grain protein content, beta glucan % and grain yield (kg ha-1) . The highest grain protein content (10.75%) and beta glucan (8.56 %) were recorded for SKO-208, followed by SKO-209 and SKO-207. The highest grain yield (394 kg/ha) was recorded in SKO-208 followed by SKO-207 and SKO-209. The cross combination SKO-208 x SKO-213 recorded for the highest grain protein content (11.89 %). The cross combination SKO-208 x SKO-209 recorded the highest beta glucan (10.23 %) content while highest grain yield (43.22 kg ha-1) was observed in cross combination SKO-208 x SKO-209. The cross combinations SKO-204 x SKO-208, SKO-205 x SKO-209, SABZAAR x SKO-209, SKO-207 x SKO-208 and SKO-208 x SKO-213were observed desirable with respect to all parameters studied. Beta-glucan content was observed to have significant and positive genotypic correlation with grain protein and grain yield.
Multi-Environment Analysis of Grain Yield and Quality Traits in Oat (Avena sativa L
Tarım Bilimleri Dergisi, 2022
Oat is used for food, in animal feeding and non-food products. Twentyfive oat genotypes were evaluated at six different environments to determine high-yielding, good-quality and stable genotypes. Experiments were conducted in randomized blocks design with 4 replications. Grain yield, plant height, test weight, thousand-grain weight, screening percentage, groat percentage, protein, β-glucan and starch contents were evaluated for 25 oat genotypes. Genotype, environment and genotype × environment interaction had extremely important effects on yield and quality of oat grains. The additive main effects and multiplicative interactions analysis disclosed important genotype and environmental effects in addition to genotype by environmental interaction according to grain yield. Using AMMI analysis, three promising oat genotypes (G1, G3 and G7) were defined in comparison to the cultivars and these genotypes had 4.03, 3.77 and 3.70 t ha-1 , respectively. AMMI-2 biplot revealed that E6 was the most discriminating environment for grain yield of oat genotypes. Genotypeby-trait (GT) biplot explained 54.9% of total variation. Grain yield were positive associated with all traits except plant height. G1, G3 and G7 genotypes, which showed the best performance and higher stability, also had good quality traits.
Some chemical, yield and quality properties of domestic oat cultivars
2014
Oat (Avena sativa L.) is one of the cereal crops cultivated in climate temperate zones. It is well known as a healthy food in the world, because of its unique biochemical structure. Nowadays the quality of grain for consumers has become important especially in terms of lipids and β -glucan content. The aim of this study was to characterize the yield, volume weight, 1000 kernel weight, husk content and kernel size distribution for two naked and three husked oat cultivars. Some quality analyses were determined, such as protein, starch, lipid and β -glucan contents. Investigations were carried out at the State Stende Cereal Breeding Institute in 2012 and 2013. The obtained results showed significant differences among naked and husked oat cultivars in all tested parameters for example lipid content for husked oat cultivars varied from 58.1–66.8 g kg -1 , but for naked oat 92.3–108.8 g kg -1 . β-glucan content among husked oat cultivars varied from 3.81–3.85 g 100 g -1 , but naked oat br...
The objectives of this research were to assess genotype environment interaction and determine stable oat (Avena sativa L.) cultivars for grain yield in Central Anatolian Region of Turkey. Stability analysis were to performed on results for grain yield of 5 oat cultivars (Chekota, Yesilkoy-1779, Yesilkoy-330, Faikbey-2004, Seydisehir-2004 from 24 trials (6 irrigated, 18 rain fed ) was conducted over 6 years in the Central Anatolian Region, Turkey. There was considerable variation in grain yield within and across environments. Year by location and location variability were dominant sources of interactions. The cultivar, "Seydisehir-2004" with respective regression coefficient value of 1.03, the smallest deviations from regressions (S 2 di ) value and the highest grain yield could be considered the most widely adapted cultivar. The other test cultivars were sensitive to production-limiting factors, their wider adaptability, stability and general performance to the fluctuating growing conditions within and across environments being lowered.
Agronomic and Quality Characterization of Oats Genotypes Selected for Winter Tolerance
2009
Although oats have recently become more and more important as human food due to its high nutritive value, oat production has not increased, even decreased in Turkey because oats are much less winter hardy than other fall-sown cereals. Therefore, improving winter tolerant oats genotypes is necessary to increase oats production. This study was undertaken to evaluate the agronomic and quality traits of twenty-three oat lines selected from a Quaker Nursery for cold tolerance in comparison to a local check. The material was grown on-farm in Kizilkaya in 2003 and in Urkutlu in 2004 in the Burdur Province of the West Mediterranean Region of Turkey using a Randomized Complete Blocks Design with three replicates. Grain yield, biomass, harvest index, 1000-grain weight, days to heading, plant height, test weight and protein contents were studied. Results showed that there were statistically significant differences among genotypes for most of the traits studied. The genotype, 95Ab1222, was supe...

The study aimed at assessing stability the grains number from panicle to autumn oats, under the influence of climatic conditions. The study was conducted over a period of three years. The biological material consisted of 73 genotypes. The experimental data was obtained by performing biometric measurements. The experimental data was processed by various linear regression analysis modelesses: Finlay-Wilkinson, Hardwick-Wood, Muir, Wrike but also the concordance between the ranks of different models of appreciation. The values of grains number in panicle fluctuate according to the climatic conditions of the year, both as an average value and as intrapopulational variability. The Jeferson, Carie, Florina varieties, and the 4458, PA 725-4743, PA 822-818 lines exhibits a high dynamic stability associated with values above the average of the experience for the number of grains in panicle. In the case of this character, 53.10% of the genotype x environment interaction is due to heterogeneit...
Field Crops Research, 2007
One hundred and twenty oat (Avena sativa L.) genotypes of worldwide origin were evaluated for agronomic and grain quality characters in three replicated field experiments in Austria and one in Germany. Panicle emergence, plant height and lodging severity were evaluated under field conditions, and grain yield, thousand kernel weight, hectolitre weight, screenings percentage > 2 mm, and groat percentage were measured after harvesting. Substantial genetic variation and high heritability were observed for all traits. The highest yielding entries were improved cultivars from European breeding programs. Groat yield and grain yield were highly correlated. For agronomic traits such as earliness and plant height, and quality traits such as groat percentage, several of the overseas genotypes, mostly from the USA and Canada, showed better performance than the European cultivars. Selected lines from the North American breeding programs appear to be valuable resources for European oat breeding programs, especially for the improvement of physical grain quality traits. #
Stability of grain number per panicle in a collection of autumn oat (Avena sativa L.) genotypes
Journal on Processing and Energy in Agriculture, 2019
The purpose of this study is to examine the stability of grain number per panicle in a collection of autumn oat genotypes under different climatic conditions. The biological material analysed consisted of 73 oat genotypes studied over a period of three years. The experimental data were obtained by biometric measurements and subsequently processed using the following linear regression models: Finlay-Wilkinson, Hardwick-Wood, Muir and Wrike. The grain number per panicle obtained varied according to the annual climatic conditions both as means and the intrapopulational variability. The Jefferson, Carrie and Florina cultivars, as well as the 4458, PA 725-4743 and PA 822-818 lines, exhibited a high dynamic stability associated with the above-average values of the grain number per panicle. Relative to this character, a total 53.10 % of the genotype x environment interaction is due to the heterogeneity of variances.
