Characterization of Durum Wheat (triticum durum L.) Landraces Regarding To Some Agronomic Traits
(Univ Namik Kemal, 2023) Aktaş, Hüsnü; Aktas, Husnu; Department of Seed Production / Tohumculuk Teknolojisi Bölümü
This research was conducted in 2019-20 wheat growing season under rainfall condition of Mardin - Artuklu province. 80 durum wheat landraces originated from Southeast Anatolia and 10 registered durum wheat cultivars were evaluated according to Augmented Trail Design. 20 landraces and 10 cultivars were used for each bloc. We determined large variations in durum wheat landraces for observed traits. Results indicated that mean of observed traits of landraces and varieties were ranged between 229 kg/da - 371 kg/da for grain yield; 1313 kg/kg - 1218 kg/kg for biomass, 18.02 % - 14.94 % for grain protein content. Mean thousand kernel weight of landraces and standard varieties changed between 42.9 g and 40.15 g; heading days ranged from 117.8 to 111 days respectively. According to observed data, landraces had longer heading days and grain stage and also higher grain protein content and biomass compare to standard varieties. Results of this study showed that landraces has high potential to increase biomass and grain protein content and they can be used as a genitor in wheat breeding programs to improving desirable durum wheat genotypes. Observation according to GGE biplot methodology (which-wonwhere) indicated that ST8 (Check) and G80 (landrace) have high values for grain yield, number of seed pers spike, seed weight per spike while G8 (landrace) showed high values for thousand grain weight, length of peduncle, plant height, grain protein content, biomass and heading days. Obtained results from this study indicated that landraces should be preserved for sustainable agriculture activities specially for marginal areas, also they have high diversity and useful traits for national and international wheat breeding programs.

Growth and Physiological Traits of Five Bread Wheat (Triticum Aestivum L.) Genotypes Are Influenced by Different Levels of Salinity and Drought Stress
(Parlar Scientific Publications (p S P), 2020) Kizilgeci, Ferhat; Kızılgeçi, Ferhat; Mokhtari, Negar Ebrahim Pour; Hossain, Akbar; Department of Seed Production / Tohumculuk Teknolojisi Bölümü
Turgor maintenance through osmotic adjustment can play a vital role in plant tolerance to drought and salinity. As per the evidence of the previous study, chemical polyethylene glycol (PEG) can create physiological drought under both salinity and water deficit conditions. Therefore, PEG is used for forcefully create osmotic stress to find out drought and salinity resistant crop cultivars at the early stage. Considering the essential role of PEG, the current observation was undertaken for understanding the effects of drought and salinity stress on several bread wheat genotypes at early developmental stage particularly during the seedling stage. Five bread wheat genotypes including four varieties such as 'Tekirdag', 'Ceyhan 99', 'Dine', 'Empire Plus' and a line 'DZ17-1' were used as seed material. To find out the genotypes which are tolerant to drought and salinity, all wheat genotypes were evaluated in four different concentration of NaCI for salinity stress (i.e., 0, 4, 8 and 12 dS/m) and four different concentration of PEG 6000 (i.e., 0, -0.2, -0.4, -0.6 MPa) for drought stress. All treatments were organised in a completely randomized design (CRD) and repeated three times. After observation, it is revealed that bread wheat cultivars 'Dine' and 'Ceyhan 99' were found tolerant of both drought and salinity stress at the seedling stage. The study also noticed that understanding of seedlings growth such as mean germination time (MGT), coleoptile length, seedling height, root length and relative water content (RWC) allow the selection of genotypes tolerance to drought and salinity. The information from the study will be helpful for examination of wheat genotypes which are suitable to cultivate under osmotic stress of both drought and salinity stress condition.

Investigation of yield stability of wheat varieties in different locations by AMMI and GGE-biplot analysis
(Springernature, 2024) Aktaş, Hüsnü; Aktas, Husnu; Akcali, Cem Tufan; Sahin, Cenk Burak; Department of Seed Production / Tohumculuk Teknolojisi Bölümü
The aim of the study was to determine the structure of GEI in the investigated parameters and to investigate the performance stability of durum wheat varieties using the GGE biplot and AMMI analysis method. The study was carried out in four different locations (Diyarbak & imath;r-1, Diyarbak & imath;r-2, Hatay, and & Scedil;anl & imath;urfa) using 31 durum wheat genotypes under rainfed conditions. Field experiments were conducted in a randomized complete block design with three replications. As a result of the study, it was determined that there was a significant difference between locations in terms of grain yield. The highest grain yield was obtained from Diyarbak & imath;r-1 (6797 kg ha-1) location, followed by Hatay (4584 kg ha-1), Diyarbak & imath;r-2 (2512 kg ha-1) and & Scedil;anl & imath;urfa (2026 kg ha-1), respectively. Significant variations in grain yield were detected among the examined genotypes, and Artuklu and Z & uuml;hre had the highest grain yields (4774 and 4501 kg ha-1). Again, Artuklu and Z & uuml;hre were the most stable varieties in terms of their performance in different locations. Diyarbak & imath;r-1 has come to the fore as the location where the variation between genotypes can be best detected. As a result, more data should be provided to plant breeders in the selection studies by considering the irrigated conditions as a factor in the studies to be carried out and determining the stable cultivars in terms of grain yield in both precipitation-based and irrigated conditions.
