Öğe A Research on The Vegetation Structures of The Rangelands of District Tufanbeyli, Adana(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2019) Cinar, Selahattin; Hatipoglu, Rustu; Avci, Mustafa; Yucel, Celal; Inal, IlkerThis research was conducted to determine vegetation structures of the upland rangelands in the five villages of Tufanbeyli district, Adana, in 2010. Vegetations of the rangelands were studied by the loop method. In the study, plant cover percentages, botanical compositions based on the cover percentage in the plant covered area, range quality values and range conditions of the rangelands studied were determined. Average percentages of grasses, legumes and other family plants in the total plant cover were determined as 36.9 %, 22.0 % and 41.1 %, respectively. It was determined that the averaged percentages of decreasing, increasing and invasive species were 20.9, 11.2 % and 67.2 %, respectively. The calculated quality values of rangelands ranged from 2.40 to 3.92, indicating that the range conditions of all rangelands studied were poor. Results indicated that grazing on the rangelands studied or on those having the same ecological conditions with the studied rangelands must be controlled, and improved by one of the range improvement methods such as over sowing, sowing or natural regeneration, alone or with the combinations of the other rangeland improvement methods. Nevertheless, new research must be conducted to determine the most proper methods of range improvement for the mentioned rangelands.Öğe DNA based iPBS-retrotransposon markers for investigating the population structure of pea (Pisum Sativum) germplasm from Turkey(Pergamon-Elsevier Science Ltd, 2015) Baloch, Faheem Shehzad; Alsaleh, Ahmad; Saenz de Miera, Luis E.; Hatipoglu, Rustu; Ciftci, Vandettin; Karakoy, Tolga; Yildiz, MehtapRetrotransposons have been highly studied in monocots; however retrotransposon diversity in dicot crops has not been well documented. Our objective was to assess the diversity harbored by field pea landraces using retrotranposon markers. In this research, molecular characterization of 104 landraces and 34 field pea breeding lines was assessed using newly developed iPBS-retrotransposon markers. The 12 iPBS-retrotransposon primers generated a total 106 scorable bands, and 81 of these were found to be polymorphic (76.4%), with an average of 6.75 polymorphic fragments per primer. Polymorphism information content (PIC) ranged from 0.33 to 0.84 with an average of 0.61. It was evident that field pea landraces from the same geographical region were often placed in different groups in the neighbor joining analysis, indicating that grouping based on genetic parameters was not closely related to the geographical origin. The population structure was determined by using STRUCTURE software, and three populations at K = 3 and five populations at K = 5 were identified among landraces. The plentiful diversity present in Turkish field pea landraces could be used as genetic resource in designing breeding program, and may also contribute to worldwide pea breeding programs. Our data also suggested a role of iPBS-retrotransposons as 'a universal marker' for molecular characterization of pea germplasm. (C) 2015 Elsevier Ltd.

In the study cultivar Nimet was used and it was evaluated for number of pods per raceme, number of seeds per pod, biomass yield, harvest index, thousand seed weight and seed yield. The results of the study indicated that row spacing and sowing rate significantly affected biomass yield and harvest index but no significant differences were found in pod number and thousand seed weight. Seed yield was significantly affected by sowing rate. The highest and the lowest seed yield were recorded in the first and third years of the experiment, respectively. The highest seed yield averaged over three years was obtained from 25 cm row spacing with 4 kg ha-1 seed rate while the lowest one was obtained from 75 cm row spacing with combining 4 kg ha-1 seed rate. Results of this study suggest that among the various row spacing and seeding rates, narrower row spacings (25 cm or 50 cm) with the lowest seeding rate (4 kg ha-1) were found to be better treatments for alfalfa seed production under Cukurova ecological conditions. © 2017, Society of Field Crops Science.

Berseem clover (BC) cv. Derya and triticale (T) cv. Tacettinbey were used as plant materials. The seed mixture ratios were sole crops BC and T, BC (80%) + T (20%), BC (60%) + T (% 40), BC (40%) + T (%60) and BC (20%) + T (80%). Forage harvest stages were beginning of flowering (HI), 50% flowering (H2) and full flowering (H3) stages of berseem clover. The experiment was established in a split plot design with four replications under lowland conditions. The mixture-ratios and harvest-stages were allocated as main plots and sub-plots, respectively. In addition to dry matter yield (DMY) and botanical composition, silage samples were evaluated for crude protein (CP), pH, acid detergent fiber (ADF), neutral detergent fiber (NDF) concentrations and digestible dry matter (DDM), relative feed value (RFV) and dry matter intake (DMI). The results of the study showed that the seed mixture of 60 % berseem clover + 40 % triticale and harvest at the 100% flowering stage of berseem clover were superior in terms of yield and selected quality parameters.Öğe Insect-resistant transgenic crops: retrospect and challenges(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2015) Bakhsh, Allah; Khabbazi, Saber Delpasand; Baloch, Faheem Shahzad; Demirel, Ufuk; Caliskan, Mehmet Emin; Hatipoglu, Rustu; Ozkan, HakanThe advent of genetic engineering has revolutionized agriculture remarkably with the development of superior insect-resistant crop varieties harboring resistance against insect pests. Bacillus thuringiensis (Bt) has been used as a main source for insect-resistant genes. In addition to Bt endotoxins, various plant lectins and other non-Bt genes from different sources have also been introduced in crop plants of economic importance. The insect-resistant crops have made a huge economic impact worldwide since their commercial release. The cultivation of insect-resistant cultivars has resulted both in increased crop productivity and in decreased environmental pollution. Although insect-resistant crops have been allowed to be commercialized following proper biosafety guidelines and procedures, still these crops face many challenges in order to be fully adopted and accepted. The degradation kinetics of Bt proteins, horizontal and vertical gene flow, effects on nontarget insects or organisms, antibiotic resistance, and some other unintended effects have been noted and discussed. Although no concrete evidence regarding any significant hazard of genetically engineered crops has been presented so far, the debate still remains intense. Impartial and professionally competent regulatory mechanisms for the evaluation of insect-resistant and other transgenic crops must be fully functionalized. The first part of this review focuses the development of different insect-resistant crops and various strategies adapted to delay resistance development in insect pests, while the second part addresses the challenges and future prospects of insect-resistant crops.Öğe Use of Genetic Engineering: Benefits and Health Concerns(CRC PRESS-TAYLOR & FRANCIS GROUP, 2016) Bakhsh, Allah; Baloch, Faheem Shehzad; Hatipoglu, Rustu; Ozkan, Hakan; Hui, YH; Evranuz, EO[Abstract Not Available]Öğe Variation of some seed mineral contents in open pollinated faba bean (Vicia faba L.) landraces from Turkey(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2014) Baloch, Faheem Shehzad; Karakoy, Tolga; Demirbas, Ahmet; Toklu, Faruk; Ozkan, Hakan; Hatipoglu, RustuThe first step towards the biofortification of edible portions of crop species with improved nutritional value is to understand the genetic diversity available to breeders in germplasm collections. A faba bean germplasm (129 landraces and 4 cultivars) from diverse geographic regions of Turkey was assessed for micro- and macro element contents of seeds. The results showed high diversity in open-pollinated faba bean germplasm for contents of N (27.5-93.3 g kg(-1)), P (1.24-4.89 g kg(-1)), K (4.5-19.3 g kg(-1)), Fe (29.7-96.3 mg kg(-1)), Mn (15.5-29.2 mg kg(-1)), Cu (10.3-33.0 mg kg(-1)), and Zn (10.4-49.3 mg kg(-1)). Meanwhile, the ranges of mineral elements in the landraces were significantly higher than those in the commercial cultivars. Concentrations of these mineral elements were significantly and positively correlated with each other. Principal component analysis clearly split the faba bean landraces into 2 groups and the first 2 principal components accounted around 70.91% of the total variations. These findings indicate a wide range of variations for the investigated minerals in the Turkish gene pool that can provide a good source of diversity to use in faba bean biofortification for increased levels of available mineral elements and better yield.Öğe Yield and quality of silage from soybean-maize intercropping(Parlar Scientific Publications, 2020) Yucel, Celal; Avci, Mustafa; Kizilsimsek, Mustafa; Hatipoglu, RustuProduction of good quality fodder is of a great importance for the economical ruminant production. The present experiment was carried out to study the effects of different sowing patterns and harvest times on digestibile dry matter yield, crude protein yield and feed quality of silages from intercropped soybean (Glycine max L.) and maize (Zea mays L.) systems. A split-plot experiment (8 sowing patterns x 2 harvest times) in randomized block design was established at the Experimental Area of Eastern Mediterranean Agricultural Research Institute in Adana, Turkey, during the growing seasons of 2010 and 2011. The sowing patterns were (1) 1 row maize to 1 row soybean (1M-1S), 2) 1 row maize to 2 rows soybean (1M-2S) 3) 2 rows maize to 1 row soybean (2M-1S) 4) 50 % maize+% 50 soybean in the same row 5) 33.3 % M+66.6 % S in the same row 6) 66.6 M+33.3S in the same row 7) sole soybeans 8) sole maize. The forage was harvested at the milk and dough stages of the maize dents. Results of the study showed that the mixture of 66.6 % maize + 33.3 soybean in the same row when harvested at dough stage could be suggested for higher digestible dry-matter yield with improved silage quality. © 2020 Parlar Scientific Publications.
