Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes
(2017) Aktaş, Hüsnü; Baloch, Faheem Shehzad
The present study was conducted to evaluate the genotype × environment interaction of the yield and quality traits for five bread wheat varieties commonly grown in the Southeastern Anatolia Region of Turkey and 20 advanced lines developed within the framework of the International Winter Wheat Improvement Project. We also determined the allelic pattern of the Glu-1 and Glu-3 loci of these genotypes and examined whether these loci had an effect on the quality traits. There was a significant variation among the genotypes and environments in terms of grain yield, protein content, sedimentation volume (SV), and the extensograph dough energy value (EDEV). The results of the study indicated that genotypic effect was more influential on SV and EDEV than environmental effect; thus, both traits could be used in breeding programs to develop elite cultivars with better quality. Twelve different high-molecularweight (HMW) glutenin alleles were identified at the Glu-A1, Glu-B1, and Glu-D1 loci, resulting in 14 allelic combinations, and 17 different alleles were observed in 19 combinations for low-molecular-weight (LMW) subunits. Furthermore, among all the genotypes, 13 + 16 and 13 + 19 alleles at Glu-B1 and 5 + 12 at Glu-D1 were observed to have the lowest frequency. Our study indicated that the combinations of HMW glutenin alleles with 2* at Glu-A1, 17 + 18 and 13 + 16 at Glu-B1, and 5 + 10 at Glu-D1, as well as the combinations of LMW alleles with subunits c and d at Glu-A3; subunits d, b, c, and g at Glu-B3; and subunits a and b at Glu-D3 had positive effects on the quality traits.
Stripe Rust Partial Resistance Increases Spring Bread Wheat Yield in South-eastern Anatolia, Turkey
(WILEY-BLACKWELL, 2016) Aktaş, Hüsnü; Zencirci, Nusret
Stripe rust caused by Puccinia striiformis f.sp. tritici is the most serious disease of wheat globally including south-eastern Anatolia of Turkey, where wheat originated. In this study, 12 spring wheat genotypes were artificially inoculated and preserved in two locations, Diyarbakr and Adyaman, during the 2011-2012 season to investigate loss in yield and yield components. Genotypes were evaluated at the adult plant stage using two partial resistance parameters: final disease severity and area under the disease progress curve (AUDPC). AUDPC ranged from 14.8 to 860 in Diyarbakr, and 74 to 760 in Adyaman. Yield loss ranged from 0.6 to 68.5% in Diyarbakr and 9.8 to 56.8% in Adyaman. Genotypes G1, G5, G7 and G8 were found to lose less yield, while higher yield loss was observed in G3, G4 (Nurkent), G5 and G9 (Karacada-98). The highest loss in thousand kernel weight was observed in a susceptible cultivar Karacada-98 in Diyarbakr followed by 43.4 and 24.4% in Adyaman. Test weight loss reached 8.89% in Diyarbakr and 20.8% in Adyaman. Yield loss and AUDPC had a positive significant relationship. Based on the values of AUDPC, final disease severity and yield loss, three major clusters were formed for 12 wheat genotypes. Partially resistant genotypes were found to lose less grain yield and seemed to be stronger against severe stripe rust pressure.
Traditional uses of wild plants in Mardin central district and attached villages (Turkey)
(INDIAN JOURNAL OF TRADITIONAL KNOWLEDGE, 2021) Kılıç, Murat; Yıldız, Kemal; Mungan Kılıç, Fatma
This research reveals traditional uses of wild plants found in Artuklu district in Mardin Province in the Southeastern Anatolia Region of Turkey. This study, conducted between 2017 and 2019, gathered information on the medicinal and other uses of plant species traditionally used in Artuklu and the local names of these plants. Face to face surveys were conducted with 183 people in 91 neighbourhoods. The ethnobotanical uses of 125 plants belonging to 35 families, which are traditionally underutilized by the local people, have been recorded. Our results showed that the highest Relative Frequency of Citation (RFC) was recorded for the species Lathyrus pseudocicera Pamp. (0.32). 1 taxon is from Stereocaulaceae of Fungi, 2 taxa are from Pteridophyta and the others 122 taxa are from Magnoliophyta. In the region, plants mostly belonging to the families Fabaceae (21 taxa), Lamiaceae (11 taxa), Asteraceae (10 taxa) and Brassicaceae (10 taxa) were determined. The recorded ethnobotanical uses are for: food (64), medicinal (40), fodder (12), children's toys (5) and various other purposes (4). Due to the fact that Turkish, Kurdish, Arabic and Assyrian people have lived together in the Artuklu district, this ethnic diversity increased the use of wild plants and added richness. Preserving the coexistence of different cultural and religious groups in the research zone is essential for the maintenance of the rich wild plant local heritage.
Variation in essential oil composition of coriander (Coriandrum sativum L.) varieties cultivated in two different ecologies
(TAYLOR & FRANCIS INC, 2017) Izgi, Mehmet Necat; Telci, Isa; Elmastas, Mahfuz
Coriander, Coriandrum sativum L, is an important medicinal plant belonging to Apiaceae family, which is grown in many parts of Turkey. In this study, essential oil and composition of 6 Turkish coriander cultivars (Gamze, Arslan, Erbaa, Pelmus, Kudret, Gurbuz) were examined in two different (Mardin and Tokat) ecologies. Essential oils were isolated with distillation method in maturated fruits and component composition was determined with gas chromatography-mass spectrometry (GC-MS). Main component was linalool in all cultivar, and it was higher in the conditions of Mardin having a warmer climate in all the cultivars than that of Tokat with temperate climate. Contrary to linalool, -pinene and neryl acetate contents of all cultivar were higher in Tokat.
