Publication Comparison of the effects of different crop rotation systems on winter wheat and sunflower under rain-fed conditions(Academic Journals, 2008-11-19) Doğan, Ramazan; DOGAN, RAMAZAN; Yağdı, Köksal; YAĞDI, KÖKSAL; Göksoy, Abdurrahim Tanju; Turan, M. Z.; GÖKSOY, ABDURRAHİM TANJU; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; 0000-0001-6415-5755; AAH-1555-2021; AAH-1546-2021The study was made to detect the most suitable crop rotation system(s) under rain-fed conditions of Southern Marmara Region, Turkey. In this study (1995-2001), two different crop rotation systems were carried out: winter wheat and sunflower as main crops experiments. Results were evaluated in terms of crop yielding ability, soil fertility and economic aspects. The sunflower-rapeseed-wheat, rapeseed-fodder pea + sunflower-wheat and rapeseed-common vetch + sunflower-wheat were found the most suitable rotation systems because of their various advantages in the first experiment in which wheat was used as main the crop. The highest sunflower seed yields were obtained from a fodder pea + sunflower-wheat-fodder pea + sunflower crop rotation system both in the first and second three year periods in which sunflower was used as main crop under rain-fed conditions. Economic analysis based on the second three-year results of the research showed that the highest mean net returns were obtained from the rapeseed-common vetch + sunflower-wheat and a fodder pea + sunflower-wheat-fodder pea + sunflower crop rotation systems under rain-fed conditions. These crop rotation systems were found the best crop rotation systems under rain-fed conditions of Southern Marmara region of Turkey. As a result, the rotation systems including common vetch and fodder peas as forage plants under rain-fed conditions gave economically the highest net profit.Publication Identification of a leaf rust resistance gene Lr24 in the bread wheat (Triticum Aestivum L.) genotypes(Parlar Scientific Publications (P S P), 2019-01-01) Polat, Pakize Özlem Kurt; Çifci, Esra Aydoğan; Yağdı, Köksal; KURT POLAT, PAKİZE ÖZLEM; AYDOĞAN ÇİFCİ, ESRA; YAĞDI, KÖKSAL; Bursa Uludağ Üniversitesi/Teknik Bilimler Meslek Yüksekokulu/Park ve Bahçe Bitkileri Bölümü.; 0000-0002-1818-7243; AAH-1528-2021; JCE-8619-2023; AAH-1546-2021; AAH-1589-2021One of the most important pathogens of wheat is leaf rust caused by Puccinia triticina (syn. Puccinia recondita Rob. ex Desm. f.sp. tritici). It causes important yield decreases in bread wheat, mainly in the years with a high infection pressure of the pathogen. DNA marker-assisted selection (MAS) have been used for the identification of leaf rust (Lr) resistance genes into adapted commercial winter wheat cultivars and bred lines. 2 F1 hybrids, 2 Thatcher line and 14 cultivar which are used commonly in Turkey and have never been idenitify for resistance against leaf rust by SSR marker linked to the Lr24 gene. The SSR marker linked to resistance gene Lr24 was robust and highly specific for these gene and will be useful in marker-assisted selection in wheat. Markers for resistance gene, Lr24 was identified in laboratory as amplification products of 310 bp, respectively. Serial PCR experiments were carried out for determination of optimal PCR conditions for Lr24 gene in our labrotary. PCR conditions were as follows: 5 min at 94 degrees C, followed by 40 cycles of 1 min at 94 degrees C, 1 min 62 degrees C depending on the primer combination, and 1 min at 72 degrees C. The last step was incubation for 10 min at 72 degrees C. The primers used in the PCR runs were as follows: After analyzed 18 genotypes, Lr24 gene was not detected except Thatcher Lr24 (positive control line).Publication The effects of treated seed pesticides on germination value of seed in some sunflower and corn cultivars(Namık Kemal Üniversitesi, 2021-01-01) Kuca, Dilara; Yağdı, Köksal; Yağdı, Köksal; YAĞDI, KÖKSAL; Kuca, Dilara; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.This research was conducted to determine the effect of different doses, which are the most common use as seed chemicals on the germination values of the seed in sunflower and corn cultivars. The research were carried out accordance with the 3-factor randomized plots experimental design in Limagrain Group / Bursa seed laboratories. Aprin XL 350 ES fungicide for sunflower in the study; 0, 200, 250, 300, 350, 400 ml and Cosmos 500 FS insecticidal; 0, 300, 400, 500, 600, 700 ml and the Maxim XL 035FS fungicide; 0,50,75,100,125,150 ml and Gaucho FS 600 insecticidal; 0,400,500,600,700 and 800 ml for corn was applied in doses. Sprayed seeds were stored for 10 days and 180 days and germination trials were conducted. According to the variance analysis results; at the end of the 10-day storage period for sunflower, the pesticide x dose interaction was statistically significant at the level of 5%, and at the end of the 180-day storage period, it was statistically significant at the level of 5% in for doses. According to variance analysis in Corn, after 10 days of storage period, cultivar and dose applications were statistically significant at 1% level, while cultivar x pesticide interaction was significant at 5%. After 180 days of storage, 1% significance was detected in all applications. As a result of the study, it has been determined that the germination values of Aprin XL 350 ES over 300 ml dose routinely applied in sunflower are negatively affected, and that this is not the case in Cosmos 500 FS application. The best dose was found to be 300 ml for Aprin XL 350 ES and 600 ml for Cosmos 500 FS. In corn, the most suitable pesticide dose varies according to cultivars and it is determined that both pesticides applied to the seed decrease the germination rate of corn in increasing doses.Publication Determination of relationships between grain yield and some yield components in bread wheat (Triticum aestivum L.)(Ankara Üniversitesi, 2015-01-01) Özlem Kurt Polat, Pakize; Aydoğan Çifci, Esra; Yağdı, Köksal; KURT POLAT, PAKİZE ÖZLEM; AYDOĞAN ÇİFCİ, ESRA; YAĞDI, KÖKSAL; Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; AAH-1546-2021; AAH-1528-2021; DMN-4308-2022This study was carried out to determine the direct and indirect effects of some yield components, such as plant height (PH), spike lenght (SL), spikelet number per spike (SNS), grain number per spike (GNS), grain weight per spike (GWS) and 1000 grains weight (1000GW), to grain yield using randomized complete block design with 3 replications in 22 advanced bread wheat line and 3 wheat varities (Flamura, Gonen, Pehlivan) at Application and Research Center, Uludag University Faculty of Agriculture, in years of 2009/10, 2010/11, 2011/12 and evaluated the relationship between agricultural traits by path analysis and correlation coefficient; was conluded that GNS and GWS can be used successfully for selection for grain yield at breeding wheat studies for Bursa conditions.Publication Effect of zinc compound (teprosyn F-2498) on wheat (Triticum aestivum L.)(Asian Journal of Chemistry, 2008-03-01) Doğan, Ramazan; Çakmak, Fevzi; Yağdı, Köksal; Kazan, Tennur; DOGAN, RAMAZAN; Çakmak, Fevzi; YAĞDI, KÖKSAL; Kazan, Tennur; Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; 0000-0001-6415-5755; AAH-1555-2021; LMC-7370-2024; AAH-1546-2021; CXW-1892-2022This research was carried out to determine the effect of zinc compound on grain yield and yield components of soft wheat cultivars.
