TAILIEUCHUNG - Some quality characteristics of selected durum wheat (Triticum durum) landraces
Durum wheat (Triticum durum) is primarily used for the production of high-quality pasta products because of its certain superior characteristics. Wheat landraces are locally adapted diverse populations evolved through natural selection and are invaluable genetic resources for breeding programs. | Research Article Turk J Agric For 36 (2012) 749-756 © TÜBİTAK doi: Some quality characteristics of selected durum wheat (Triticum durum) landraces Abdulvahit SAYASLAN1,*, Mehmet KOYUNCU1, Ahmet YILDIRIM2, Tuğba ESERKAYA GÜLEÇ2, 2 3 Özlem ATEŞ SÖNMEZOĞLU , Nejdet KANDEMİR 1 Department of Food Engineering, Faculty of Engineering, Karamanoğlu Mehmetbey University, Karaman - TURKEY 2 Department of Biology, Kamil Özdağ Faculty of Science, Karamanoğlu Mehmetbey University, Karaman - TURKEY 3 Department of Field Crops, Faculty of Agriculture, Gaziosmanpaşa University, Tokat - TURKEY Received: ● Accepted: Abstract: Durum wheat (Triticum durum) is primarily used for the production of high-quality pasta products because of its certain superior characteristics. Wheat landraces are locally adapted diverse populations evolved through natural selection and are invaluable genetic resources for breeding programs. The search for new genetic resources all around the world has been underway to develop high-quality durum wheats. The purpose of this study was therefore to determine the pasta quality-associated characteristics of 12 durum wheat landraces (Bağacak, Beyaziye, İskenderiye, Sorgül, Karakılçık, Beyaz Buğday, Ağ Buğdayı, Bintepe, Havrani, Çalıbasan, Hacı Halil, and Akçakale) compared to 2 wellestablished high-quality durum wheat cultivars, Kyle and Zenit. Protein content and quality, pigment content, activities of oxidative enzymes (lipoxygenase, polyphenol oxidase, and peroxidase), kernel size, and endosperm vitreousness were measured as the major quality parameters. The landraces had significant differences (P 10,000 rpm for 10 min) to obtain a clear supernatant. Upon appropriate pretreatments, the extracts were loaded onto a precast A-PAGE system, run at 15 °C for 3-4 h at 500 V, stained with Coomassie Brilliant Blue R-250 dye preparation, and then evaluated as described by Bushuk and Zillman (1978) and Khan et al. .
