Assessment of Genetic Variation on Some Cultivated Turkish Coriander (Coriandrum Sativum L.) Varieties Based on Issr and Srap Markers
(Centenary University, 2017) Furan, M.A.; Geboloğlu, M.D.
Coriandrum sativum L. is the spices plant that used as medicinal plant including essential oil, belonging to the family Umbelliferae/Apiaceae. Its various chemical components in different parts are useful as antibacterial, antifungal and antioxidative. Therefore plays a major role in preserving the shelf life of foods by preventing their spoilage. Leaves and seeds of coriander mostly used in folk medicine and its essential oil used for pharmaceutical products and as an ingredient in perfumes cause of non-toxic to humans. Coriander is not much defined as molecularly. Coriander breeding studies will probably result in more or less genetically identical varieties of Coriandrum sativum L. The acceptability of the genotypes is determined by the amount of genetic variability in the germplasm and the utilizable information is limited in coriander. Studying to determine the genetic diversity of identified characters and emphasis of importance to use convenient genotype in a breeding program is needed in order to enlarge the genetic base in coriander. In this study; Genetic variations among some Turkish coriander varieties were investigated at the DNA level using two different marker techniques (ISSR and SRAP) and the aim was to determine the genetic relationship between these traded varieties. Both primers gave totally 473 scorable bands and all results from each marker have shown the phylogenetic relationships between genotypes. © 2017, Centenary University. All rights reserved.
Determination of Genetic Diversity Among Some Turkish Spring Bread Wheat Varieties Using Ssr Markers
(Centenary University, 2017) Geboloğlu, M.D.; Furan, M.A.
Wheat in grain, is a food source with high strategic importance and it was cultured since ancient times. Since the increase of population in the world, it was necessary in order to increase the yield per unit area. Increasing yield per unit area of wheat, can be achievable by various breeding methods. Knowing the genetic similarities - differences of plant genetic resources are very important for breeding. In recent years, molecular marker methods are often preferred in wheats. This study was aimed to molecular characterization of 23 bread wheat varieties which collected from different regions of Turkey using capillary electrophoretic method for 32 SSR primers. As a result of molecular marker analysis the genetic similarities and differences between the varieties are revealed at the molecular level. In addition, this study emphasizes once again the importance and necessity of using molecular markers for breeding studies. © 2017, Centenary University. All rights reserved.
Evaluation of Yr-26 Yellow Rust Disease Resistance of Endemic Tir Wheat (Triticum Aestivum L. Ssp. Vulgare Vill.v. Leucospermum Körn) Genotypes Using Resistant R55 (6al / 6vs) Translocation Line and Locus Specific Ssr Markers
(Centenary University, 2017) Furan, M.A.; Geboloğlu, M.D.; Arpali, D.
Wheat is the most important food product in the world and has been cultivated as an essential product since human settlement. Endemic wheat genotypes may have different source genes in terms of resistance to diseases. However, many farmers cultivate modern varieties resulting from national and international breeding program. Previous studies have demonstrated that some of these varieties are not resistant to one or more diseases. Therefore, a rich variety program is an attempt to make an assessment the potential donor of local and exotic varieties of wheat. In this study, yellow rust resistance of Tir wheat has been studied at the molecular level which is a local genotype frequently cultivated in Van Lake Basin in Turkey. As a simple and practical approach, R55 (6AL / 6VS) translocation line that contains yellow rust resistance gene Yr-26 and Near Isogenic Lines which having known the disease resistance genes Yr-1, Yr-7, Yr-3 and Yr-4 were examined using the SSR markers identified by Gatersleben Wheat Microsatellite (Xgwm) and Beltsville Agricultural Research (Xbarc) which is known to be associated with YR resistance genes and closely related to the respective gene regions on the chromosome. Observed rust, surveying was determined as medium sensitive “MS” according to the Cobb scale value. Totally 212 polymorphic bands obtained from the using SSR primers and the mean number of the polymorphic band found as 5.2 for each primer and the polymorphic information content of the evaluated primers varied between 0.37 and 0.41. The local Tir genotypes have found to be closely related to genotypes known having the yr-2 and yr-3b, 4b resistance genes. © 2017, Centenary University. All rights reserved.
