In this study, 196 Turkish oat landraces and three standard cultivars (Checota, Faikbey and Seydişehir) were evaluated for grain yield, yield components and some quality traits for two years. Based on two years experiment data, all investigated traits were significantly different for years, except panicle length and protein ratio. Genotypes varied for grain number per panicle, grain weight per panicle, panicle length, 1000-grain weight, grain yield, groat percentage and protein ratio. However, year x genotype interaction was only important for grain yield, groat percentage and protein ratio. According to the investigated traits, grain yield, grain weight per panicle and 1000-grain weight traits were more promising than grain number per panicle, panicle length, groat percentage, protein ratio, tiller number per plant and panicle number per m2. These results indicate that, E35, E39, E21, E34, E13, A16, E17, E37, E26, A27, A9, A10, E20, A79, E19, E56 A59, K13, K43, A19, E47, K7, K4, K3 and A7 were some of the genotypes with higher grain yield, 1000-grain weight and grain weight per panicle.

Ripe persimmon fruit (Diospyros kaki L) cv. " Hachiya" were diced, then treated with 10-20% w/v diluted honey solution or water as the control, followed by cold storage at 4C until loss of acceptable quality. The persimmon cubes were subject to assessments during the storage of organoleptic and visual quality, softness and exuding juice, soluble solids content (SSC), and absorbance at 436, 440, 675 and 760 nm,respectively. Honey treatments prevented off-aroma development and delayed jelling. Softness and exuding juice of the fresh-cut persimmon cubes increased with time, with the increase in both parameters being significantly suppressed by honey solution dips. Changes in SSC, pH and the absorbance at 436, 440, 675 and 760 nm, respectively, during storage were minor and there was little effect of the honey treatments on these parameters. Overall, the shelf life of fresh-cut persimmon cubes was extended by honey solution dips, which delayed off-aroma development, firmness loss and jelling. © 2010 The Author(s).

This research was carried out to determine the advantages of mixed cropping of bread wheat (BW) and triticale (T) compared to pure cropping, during three cropping years, under the East Mediterranean Region of Turkey. Bread wheat and triticale mixtures were arranged in a ratio as 100:0, 80:20, 60:40, 40:60, 20:80 and 0:100. Sowing rates were 550 seed m-2 for all plots. According to the results, grain weight per head (GW H-1), grain number per head (GN H-1), ratio of grains in mixed cropping (RGMC) of BW, protein ration (PR) and dry gluten (DG) amount of products were significantly decreased by increasing of T plants in the mixed cropping plots, compared to pure cropping of BW. Triticale was the highest yielding (9250 kg ha-1) component of mixed cropping. Contributions of triticale plants were also significant for grain yield of mixtures. In addition, relative yield total (RYT) and indices of inter-specific competition (Rbwt and Rtbw) indicated that, mixed cropping of BW and T did not have any advantages for GY over the pure cropping of triticale. The year x mixed cropping interaction was only significant for GN H-1. Source

In a two-year study, 196 Turkish oat landraces and 3 standard cultivars ('Checota', 'Faikbey' and 'Seydişehir') were evaluated for morphological traits: germination rate, stem diameter, upper inter-node length, plant height, flag leaf width, flag leaf length, single plant biomass, lodging severity and barley yellow dwarf virus, and for phenological traits: vegetative period, grain filling period and, days to maturity. According to two years' data, all traits differed for years except germination rate. Genotypes varied for upper inter-node length, stem diameter, plant height, flag leaf width, vegetative period, grain filling period and days to maturity. In addition, year × genotype interaction was significant for stem diameter, flag leaf width, vegetative period, grain filling period and days to maturity. Traits such as flag leaf length, flag leaf width, days to maturity, vegetative period, single plant biomass and germination rate were more promising ones as selection criteria. However, lodging severity, plant height, barley yellow dwarf virus, upper inter-node length and grain filling period were more important for negative selection. Results indicate that, E1, A56, E7, E55, A17, E38, A40, A63, A25, A69, A26, A83, A1, A2, K11, K9, K3, K53, K30, K1, K2, K7, K5, K8, K48 and K4 were some of the genotypes in the right quadrants of the biplot with vegetative period, days to maturity, flag leaf width, flag leaf length, germination rate, single plant biomass and stem diameter traits.

The aim of this research was i) to evaluate the oat genotypes for grain yield and physiological traits, ii) to investigate the oat genotypes having the highest grain yield in the conditions of research region and the relationships between grain yield and traits, iii) to investigate the genetic improvements of registered oat cultivars for grain yield and traits by the year of release. This research was carried out using 8 oat landraces and 9 registered oat cultivars, sown in a randomized complete block design with four replications, between 2006 and 2008 in Kahramanmaras city conditions. In the research, leaf area index (LAI), chlorophyll content (CC), canopy temperature (CT), leaf area duration (LAD), stomatal conductance (g s), net photosynthetic rate (A), 1000-grain weight (1000-GW), biomass at maturity (BM), grain yield (GY) and harvest index (HI) were investigated. According to the average of two years, genotypes were significantly different for all investigated traits except for CT, g s, A, 1000-GW. The highest grain yield 4246.5 kg ha -1 in the conditions of the region was produced by the 'Checota' cultivar. In this research, we found significant and positive relationships between GY and LAI, CC, LAD, HI by the Pearson correlation coefficients. The result of linear regression analysis according to GY and the year of release of registered cultivars showed significant improvements (51.1 kg -1 ha -1 year) in the oat grain yield by the year 1986. There was not any improvement for GY of the cultivars registered after 1986. Source
