    Agronomic and quality evaluation of rainfed barley (Hordeum vulgare L.) in eastern Mediterranean condition
    (Parlar Scientific Publications, 2018) Ay, Hasan; Aykanat, Sait; Anay, Ayse; Akkaya, M. Reis; Zeybek, Ahmet
    Using agronomic and quality characteristics, genotypic and phenotypic performance of barley lines were investigated in East Mediterranean condition in Turkey in three consecutive years from 2012 to 2014 based on randomized complete block design. Growing seasons had dramatically different climatic conditions therefore, years were considered as different environments. 2014 was the best selection environment for drought tolerance. Agronomic traits such as heading date (HDD), maturity date (MTR), plant height (PHT), lodging rate (LRT), lodging angle (LAN), grain yield (YLD,) thousand kernel weight (TKW), hectoliter weight (HKW), barley leaf spot (SCALT) tolerance scoring, as well as quality traits such as fat, fiber, protein (PR) and starch (STR) contents of barley genotypes were measured in the three different environments. Results showed that YLD was mostly correlated with PHT, MTR and FBR. All traits except PHT, HWT and PRT were significantly affected by genotype x environment interaction. Yield component traits such as TKW and HWT was moderately high in terms of heritability values while quality traits of FAT and PRT was contained highest heritability values. 13 lines and one cultivar of tested 25 genotypes were stable at yield over three environments. The highest yielding genotype was G16 in 2012. While G10 was the highest yielding genotype in drought conditions of 2014. All lines competed well with cultivars over three environments. In the present study, some barley lines appear to carry useful alleles for stable yield and quality traits. The results of this study will be helpful for barley breeders and farmers to improve and make use of barley cultivars adaptable for Mediterranean environments. © by PSP.

    Physical and chemical properties of some pistachio varieties (Pistacia vera L.) and oils grown under irrigated and non-irrigated conditions in Turkey
    (Wageningen Academic Publishers, 2018) Kola, O.; Hayoglu, I.; Turkoglu, H.; Parildi, E.; Ak, B. Erol; Akkaya, M. Reis
    The purpose of this study was to compare physicochemical characteristics and fatty acid profiles of two varieties (Kirmizi and Siirt) of pistachio nut (Pistacia vera L.) and to determine the effects of irrigation on some chemical characteristics and fatty acid composition. It was observed that while the irrigation caused an increase in Pistachio nut yield, crude fibre, ash and oil content of the nuts and decrease in protein content, it had no effect on kernel and nut sizes and dry matter contents. Variety affected primary fatty acids markedly, but irrigation did not. Total lipid levels in two varieties of pistachio were between 53.09 and 56.11%. The results showed that the most abundant fatty acid in pistachio oils was oleic acid, composing between 70.47 and 75.82% of the total fatty acids. The oil of Kirmizi pistachio variety had the highest linoleic acid content (17.72%) under irrigated conditions. Total saturated fatty acids of pistachio nuts were less than 12.02%, monounsaturated and polyunsaturated fatty acids totalled up to 77.07 and 17.99%, respectively.
