Analysis of Promising Barley (Hordeum Vulgare L.) Lines Performance by AMMI and GGE Biplot in Multiple Traits and Environment
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Tekdal, S.; Dogan, S.; Kendal, E.; Karaman, M.
The development of stable and adaptable new cultivars are based only on positive results obtained from the interaction between the genotype and the environment. Therefore, the study aimed to test the stability and general adaptability of promising barley lines in terms of grain yield and traits in multi -environments. For this purpose, twelve barley genotypes were used in the study. The trials were carried out with four replications in a random design at seven environments in years 2012-13 and 2013-14. The superior and stable genotypes were identified with GGE biplot and AMMI (Additive main effects and multiplicative interaction) models. The AMMI analysis showed that the major treatment sum of squares was affected by environments (80.6%), GE (14.0%) and genotypes (5.4%), respectively. On the other hand, the first two principal component axes (PCA 1 and PCA 2) contributed to the complete interaction with 88.1%, whereas, PCA 3 and PCA 4 axes only with 12.0%. The GGE biplot indicated that G4 is adaptable for all environments, while Altikat, G2 and G3 showed specific adaptation to El, E3 and E5, G6, G7 and G8 to E6, respectively. According to both techniques, G2, G3, G6, G7, G8 and Altikat were the best genotypes with high yield, whereas G4 was the best with high yield, and stable and general adaptation. The results of biplot indicated that G4 (ARUPO /K8755//MORA/3/CERISE/SHYRIHALEL I/4/CANELA/5/HART-BAR) was recommended for release and it was released as HEVSEL in 2017. On the other hand; G7 and G6 were protected as genetic material to use as parent in breeding programs for yield stability and quality respectively.

Clonostachys rosea Strain ST1140: An Endophytic Plant-Growth-Promoting Fungus, and Its Potential Use in Seedbeds with Wheat-Grain Substrate
(SpringerLink, 2023) Türkölmez, Şahimerdan; Özer, Göksel; Derviş, Sibel
In this study, Clonostachys rosea strain ST1140, a naturally occurring endophyte in healthy roots of a pistachio tree, was identifed morphologically and molecularly through DNA sequencing, and its endophytic ability and growth efect in/on three solanaceous plant species were tested. Three diferent organic substrates (bread wheat-grain, sawdust, and leonardite) were also investigated for their utility in cultivating and multiplying the strain. In-tray and pot experiments, the rates of seed germination and vegetative development of pepper, tomato, and eggplant inoculated with C. rosea at planting were compared to those of non-inoculated controls. In pot experiments, inoculating seedbeds with increasing doses of C. rosea strain ST1140 with wheat-grain substrate resulted in higher plant height values for all plant species, and the strain endophytically colonized the roots of all plant species. In-tray experiments revealed that ST1140 inoculation resulted in 2–4 days earlier and 10% higher germination rates for all plant species, as well as more vigorous and accelerated seedling growth (10–13 days earlier for seedlings at the 4–5 true leaf stage) on all inoculated plant species. Among three diferent organic substrates, wheat-grain was found to be the most efective for long-term cultivation and multiplication of the fungus, which could be of interest for its development as a commercial product. These results promised the strain ST1140’s use as a biofertilizer in seedbeds with a wheat-grain substrate.

(Yüzüncü Yıl Üniversitesi Tarım Bilimleri Dergisi, 2022) Yılmaz, Melikşah; Kızılgecı, Ferhat; Tazebay Asan, Nihan; Asan, Ufuk; Iqbal, Asif; Iqbal, Muhammad Aamir
Under changing climate, abiotic stresses especially salinity have posed serious threats to modern crop production systems of staple crops and chemo-priming with salicylic acid offers a promising remedy. The present study aimed at ameliorating the adverse effects of salt stress through optimization of salicylic acid (SA) for two bread wheat genotypes (DZ17-1 and Empire Plus). The trial was comprised of chemo-priming with different SA levels including 0, 0.5, and 1 mM applied to the seeds of bread wheat genotypes exposed to different salinity levels (0, 50, 100, 150, 200 mM NaCl). The response variables included germination indices, roots length, and weight along with seedling traits. The results revealed that increasing the level of salinity had a negative effect on both genotypes of wheat and all traits studied. The DZ17-7 genotype was found to be more tolerant to salt stress. Among SA concentrations, 1 mM imparted a significant influence on germination, root traits, and seedling parameters. Although SA showed positive effects in salt stress conditions in the study, further studies are needed to clarify the role of SA in providing stress tolerance of plants.

(Aloki Applied Ecological Research and Forensic Inst Ltd, 2019) Dogan, Y.; Togay, N.; Togay, Y.
The aim of this study was to determine the most suitable irrigation schedules and sources of manure for maize under Mardin ecological conditions. For this purpose, four sources of fertilizer and three irrigation schedules were applied in hybrid maize cultivar to find out their effects on the yield and yield factors in the years of 2014 and 2015. The study used a randomized complete block with split block design with 3 replications. In the study, significant differences were determined on traits at the level of 1% and 5%. The plant height, first cob height, cob length, number of seeds per cob, cob yield, 1000 seed weight, seed yield per unit, hectoliter, protein and oil ratio in seed, Mg, K, Fe, Ni, Cu, Zn, Mn, Na, Ca content of seeds were significantly influenced by irrigation schedules and sources of fertilizer for two years. The highest values were obtained from chicken manure with 9646 kg ha(-1) in the first year and 11019 kg ha(-1 )in the second year, whereas the lowest values were obtained from control with 6363 and 6662 kg ha(-1) for the first year and the second, respectively. But the difference between 180-80 kg N-P(2)0(5) ha(-1) and chicken manure was not statistically significant in the second year. According to the irrigation schedules, the grain yield ranged between 6386-10678 kg/ha in the first year and 7575-12133 kg ha(-1) in the second year. The lowest grain yield per area was from the four-irrigation application, whereas the highest values were obtained from the six-irrigation application. The results of the study showed that grain yield and nutrient level of corn seeds increased, depending on irrigation time and number.

(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2016) Aktaş , Hüsnü
The present study was performed to determine performance of selected four synthetic derived bread wheat genotypes, four bread wheat landraces and four modern wheat genotypes under rain-fed and supplemented irrigation experiments based on randomized complete block design with four replications at GAP International Agricultural Research and Training Center, Diyarbakır, Turkey in 2013-2014 and 2014-2015 growing seasons. According to results of pairwise correlation and biplot analysis, significant and positive correlation was observed between grain yield in stress condition (Ys) and stress tolerant index (STI), geometric mean productivity (GMP), mean productivity (MP), harmonic productivity (HM), yield stability index (YSI), yield index (YI), drought resistance index (DI) and stress non-stress production index (SNPI) indicating these indices can be used as parameters for evaluating drought tolerant genotypes. Negative correlation between grain yield in stress (Ys) with SSI and no correlation with TOL indicated that these indices should be used in severe drought conditions for screening genotypes. Number seed in spike (NSS), plant height (PH) and thousand kernel weight (TKW) correlated with grain yield in stress conditions (Ys) according to biplot analysis, also genotypes with lower reduction relating to these traits had higher yield in stress conditions. According to results SEN-DER genotypes G7, G10, landrace group genotype G11 (Sorık) were determined as the most tolerant genotypes to be used to improve drought tolerant varieties, while modern wheat genotypes G4 (Ceyhan-99) and G2 (Tekin) were high productive in irrigation conditions and low productive in rain-fed conditions.

Effect of Different Harvest Dates to Essential Oil Components of Oil-Bearing Rose (Rosa damascena Mill.) in Mardin
(Taylor & Francis Online, 2022) İzgi, Mehmet Necat
Rosa damascena Mill. is the most prominent rose source for the manufacturing of rose oil, rose water, concrete, and absolute from flower petals. The purpose of this study was to see how different harvest dates affected the essential oil components and rates obtained from flowers in oil rose planted for the first time in Turkey's Mardin Province. Blossoms were taken five times with three replications, at around one-week intervals, from a garden in the Yaylabaşı district at 6:00 a.m. (4, 11, 18, 24, and 31 May). Animal manure and leonardite were used instead of chemical fertilizers for plants. No chemical pesticides have been applied. Essential oil components of the oils obtained by a water distillation system (Clevenger apparatus) were determined by GC/MS. The citronellol ratio, which is the most important component for the quality of the essential oil in the plant, was found to be highest (35.90%) in the first harvest period and lowest in the last harvest period (17.57%). Geraniol levels decreased in the first three harvests, with the greatest level (27.16%) coming in the last harvest. The percentages of citronellol/geraniol varied between 1.51 and 0.65 depending on the different harvest dates. Nerol rates peaked at 15.44% on the first harvest, progressively declined until the fourth harvest (7.92%), then slightly increased on the fifth harvest. Nonadecane continuously increased from the first to the last harvest (4.10%-11.66%). No methyl eugenol was detected. Mardin is a promising location for oil-bearing rose cultivation, given the essential oil components and their ratios.

(Aloki Applied Ecological Research and Forensic Inst Ltd, 2020) Izgi, M. N.
In a two-year study, under the environmental conditions of the plains of Mardin province in Turkey, the effects of different doses of phosphorus (0, 30, 60, 90, 120 kg ha(-1)) on the yield and quality characteristics of the coriander (Coriandrum sativum L.) were examined. Plant characteristics such as plant height, number of branches, number of umbels, thousand seed weight and seed yield were examined, besides quality characteristics such as essential oil rate and composition. The essential oil was isolated with a Clevenger apparatus from mature fruits. Essential oil components were determined with Gas chromatography-mass spectrometry (GC-MS). The results revealed that phosphorus doses affect the plant characteristics of coriander including plant height, number of branches, number of umbels and thousand fruit weight with positive significance. Fruit yield was not affected significantly. Phosphorus doses had a significant positive effect on essential oil rate. Increasing phosphorus doses affected rates of alpha-pinene, geranyl acetate and camphor positively. However, Linalool and gamma-terpinene were not affected by phosphorus doses significantly. The application of 120 kg phosphorus per hectare, which had the highest essential oil rate in both years, can be recommended in coriander farming.

Coriander (Coriandrum sativum L.) is a spice plant belonging to the Apiaceae family. In this study, the aim was to specify the effects of different nitrogen doses on the yield and quality properties of coriander. In this research; plant height, number of branches, number of umbels, thousand seed weight, seed yield, oil content, fatty acid composition, essential oil rate and essential oil composition were examined. The essential oil contents in coriander fruits was determined by Clevenger apparatus. Fatty oil was isolated by cold press. Essential oil and fatty oil compositions were determined by Gas chromatography-mass spectrometry (GC/MS-QP2020) device. While nitrogen doses did not positively affect fruit yield, they had a significantly positive effect on the herbal characteristics of coriander (plant height, number of umbels and thousand fruit weight). It was revealed that nitrogen doses had positive significant effect essential oil rate. Increasing nitrogen doses affected rate of linalool. Nitrogen doses had a significant effect only on butyric acid, and for fatty oil rate and other major fatty acids their effect was not significant. It has been determined that high fruit yields are obtained at 60 and 80 kg ha(-1) nitrogen applications and that the rate of essential oil and linalool is the highest at 100 kg ha(-1) nitrogen doses especially in the second year.

(Soc Field Crop Sci, 2020) Ahmed, Asgar; Hossain, Akbar; Amiruzzaman, Md; Alam, Md Ashraful; Farooq, Muhammad; El Sabagh, Ayman; Kizilgeci, Ferhat
In Bangladesh, maize stands second place after rice; since it faces diverse natural calamities during its highest growing season (rabi/winter), particularly strong storm during the reproductive stage. Sometimes in some regions, this crop is completely damaged by natural disasters. Considering the burning issue, thirteen hybrids, including 10 previously selected short stature hybrids were evaluated against three local and standard checks: 'BHM-9', '981' and 'Sunshine' in two consecutive years in seven locations of Bangladesh. Combined analysis over locations and seasons instigated that genotypes 'Sunshine', '981' and 'G10' were the top-high yielders, while genotypes 'G1', 'G2', 'BHM-9' and 'Sunshine' were found the most stable. On the other hand, five genotypes such as 'G3', 'G4', 'G6', 'G8' and 'G9' had the below-average mean yield and the genotypes 'G6' and 'G9' were the most unstable. Among the seven environments, Jamalpur, Joydebpur and Dinajpur were most discriminating and Ishwardi was the least discriminating; whereas Joydebpur was more representative and Borishal was the least representative of other test environments. In the case of plant and ear height, most of the genotypes showed a lower value than all the checks, which was desirable. But among the top three high yielders, local cross-genotype, the 'G10' had the lowest and more stable value for both plant height and ear height. Therefore, considering the plant and ear height, grain yield, and yield stability, the genotype 'G10' has been recommended for release as commercial variety and has been released as new maize variety in Bangladesh with the local name of 'BARI Hybrid Maize-16' (BHM-16).

(SpringerLink, 2022) Kızılgeçi, Ferhat; Bayhan, Bora; Türkoğlu, Aras; Haliloğlu, Kamil; Yıldırım, Mehmet
Background: Turkey is not only a center of origin for wheat, but also contains wild forms of various cereals. Turkey, located in the Fertile Crescent, has conserved its genetic richness to the present day. The aim of the study was to investigate the genetic diversity of 70 wild wheat species, to evaluate the structure of diversity in germplasm and to generate useful data for further breeding programs. Methods and results: Genetic diversity and population structure of 70 wild wheat species (Ae. cylindrica, Ae. geniculata, Ae. triuncialis, T. dicocoides, Ae. columnaris) collected from Eastern and Southeastern Anatolia regions of Turkey were investigated in this study with the use of inter-primer binding site (iPBS) markers. Of 35 iPBS primers used, 11 yielded a total of 61 alleles. Number of alleles per marker varied between 2 (iPBS-2085) and 9 (iPBS-2394) with an average value of 5.55. Polymorphic information content (PIC) values varied between 0.22 and 0.47, with an average value of 0.35. Average number of effective alleles (Ne) was identified as 1.9488, Nei's genetic diversity (H) as 0,4861 and Shannon's information index (I) as 0.6791. Cluster analysis through unweighted pair-group mean average (UPGMA) method revealed that 70 wild wheats were divided into three main clusters. Genetic similarity between the genotypes, calculated with the use of NTSYS-pc software, varied between 19% (YB2 and YB70) and 98% (YB66 and YB67). Principal coordinate analysis (PCoA) revealed that three principal coordinates explained 62.33% of total variation. Moreover, population structure analysis showed that all genotypes formed three sub-populations. Expected heterozygosity values varied between 0.2666 (the first sub-population) and 0.2330 (third sub-population), with an average value of 0.2500. Average population differentiation measurement (Fst) was identified as 0.3716 for the first sub-population, 0.3930 for the second subpopulation and 0.4804 for the third sub-population. Conclusions: Based on present findings population structure of 70 wild wheat genotypes collected from Eastern and Southeastern Anatolia regions of Turkey were successfully characterized with the use of iPBS markers. Present findings suggested that iPBS-retrotransposon markers could reliably be used to elucidate genetic diversity of Aegilops genotypes.

Molecular phylogeny of plant pathogenic fungi based on start codon targeted (SCoT) polymorphism
(Springer, 2023) Palacıoğlu, Gülsüm; Alkan, Mehtap; Derviş, Sibel; Bayraktar, Harun; Özer, Göksel
Background: A number of molecular marker systems have been developed to assess genetic diversity, carry out phylogenetic analysis, and diagnose and discriminate plant pathogenic fungi. The start codon targeted (SCoT) markers system is a novel approach used here to investigate intra and interspecific polymorphisms of phytopathogenic fungi. Materials and methods: This study assessed genetic variability between and within 96 isolates of ten fungal species associated with a variety of plant species using 36 SCoT primers. Results: The six primers generated 331 distinct and reproducible banding patterns, of which 322 were polymorphic (97.28%), resulting in 53.67 polymorphic bands per primer. All primers produced informative amplification profiles that distinguished all fungal species. With a resolving power of 10.65, SCoT primer 12 showed the highest polymorphism among species, followed by primer 33 and primer 29. Polymorphic loci (PPL), Nei's diversity index (h), and Shannon index (I) percentages were 6.25, 0.018, and 0.028, respectively. UPGMA analysis separated all isolates based on morphological classification and revealed significant genetic variation among fungal isolates at the intraspecific level. PCoA analysis strongly supported fungal species discrimination and genetic variation. The other parameters of evaluation proved that SCoT markers are at least as effective as other DNA markers. Conclusions: SCoT markers were effective in identifying plant pathogenic fungi and were a powerful tool for estimating genetic variation and population structure of different fungi species.

The nutlet (mericarp) morphology of nine species of Salvia sect. Salvia (Salvia bracteata Banks & Sol., Salvia macrochlamys Boiss. & Kotschy, Salvia suffruticosa Montbret & Aucher ex Benth., Salvia trichoclada Benth.), Hymenosphace (Salvia multicaulis Vahl), Aethiopis (Salvia montbretii Benth., Salvia palaestina Benth., Salvia syriaca L.) and Hemisphace (Salvia russellii Benth.) (Lamiaceae) has been studied by scanning electron microscopy (SEM), and a detailed description of the nutlet morphological features of all examined taxa is provided. The basic shape of nutlets in most species is subprolate or prolate and the size ranged between 3.02 and 6.47 mm in length and between 1.78 and 5.10 mm in width. Three basic types of sculpturing can be distinguished: colliculate, reticulate and verrucate. The colliculate type is the most common among the studied species. The colliculate type is characteristic for sect. Salvia. Subsection Salvia with colliculate/slightly furrowed sculpturing is easily distinguished from the other subsections.
