Öğe ADAPTATION ABILITIES AND QUALITY PARAMETERS OF SELECTED SOYBEAN LINES UNDER DOUBLE CROPPING IN THE MEDITERRANEAN REGION(Soc Field Crop Sci, 2018) Ilker, Emre; Kocaturk, Mehmet; Kadiroglu, Abdullah; Yildirim, Aliye; Ozturk, Gulsum; Yildiz, Hakan; Koken, IbrahimThe objective of this study was to determine the adaptation abilities and quality parameters of selected advanced soybean breeding lines at the double cropped growing conditions. 20 advanced Soybean [Glycine max (L.) Merr] breeding lines (F-7) and four soybean varieties having maturity group HI and IV (ARISOY, ATAEM-7, BRAVO and NOVA) were used. The differences between the lines and varieties were significant for the grain yield. The mean grain yield of breeding lines and varieties ranged from 2460 to 3488 kg ha(-1) and from 2933 to 3440 kg ha(-1), respectively. Also KA-07-05-13 advanced soybean line had the highest grain yield in terms of two years' average. The highest plant height was obtained from KA-07-08-15 (82.2 cm) and the lowest pod height from KA-07-08-15 (12.2 cm) and BDNA-19 (12.1 cm) lines. Significant differences were determined for pod number per plant among the 24 soybean genotypes. The pod number per plant was the higher in BDNA-12 and BDNA-13 lines than the varieties. In this research, the number of day for flowering varied between 33.0-42.1 days and the number of days for maturating ranged from 102.4 to 113.6 days. The earliest flowering time was detected from KA-07-08-14 line and the earliest maturating time was observed from BDNE-14 line. In a two-year average, 100-seed weight ranged between 14.2-20.8 g in breeding lines. The highest 100-seed weight was obtained from KA-07-03-5 (20.8 g) and KA-07-03-9 lines (20.1 g). While the highest oil percentage was obtained from ARISOY, the highest and statistically same oil percentage was recorded from KA-07-05-9 (21,6%), KA-07-08-12 (21,2%) and KA-07-05-5 (21,2%). The average protein content of soybean lines and cultivars varied from 41.6% to 49.3%. The higher protein percentage value was obtained from the BDAF-4 (49.3%) breeding line.Öğe COMPARISON OF OLD AND NEW CLONES OF POTATO NUCLEAR SEED STOCKS FOR TUBER UNIFORMITY IN THE GREENHOUSE(Soc Field Crop Sci, 2014) Ozturk, Gulsum; Yildirim, ZihinThe plantlets of old and new clones micropropagated from nuclear seed stocks were grown in the greenhouse to compare their tuber uniformity. The old and new clones nested in cultivars Agria, Hermes and Granola, were grown in Completely Randomized Plots design in the fall, 2012 and in the winter, 2013. The tuber characteristics were measured and the standard analyses of variance technique were applied and the regression coefficients of the means of new clones on the means of the old clones were estimated for tuber number, single tuber weight (g), single plant yield (g), plot yield (g), tuber width and tuber length. The F values for the clone type and clone were non significant indicating the uniformity of the means of the old and new clones. In addition, the b values of the regression of the means of the new clones on the means of the old clones were found to be equal to 1 supporting the hypothesis of the uniformity of the old clones and new clones for tuber characteristics.Öğe DETERMINATION OF SWEETPOTATO [Ipomoea batatas (L.)

Yapılan karşılaştırma ve değerlendirmeler sonucu elde edilen bulgulara göre; iki popülasyon arasında yumru sayısı, tek yumru ağırlığı ve bitki verimi için korelasyon değerlerinin seleksiyonuı olumlu etkileyeceği kabul edilebilir. 2. uygulanan seleksiyon sonucu, yumru sayısı için p=0,05 oranında en yüksek seleksiyon diferansiyeli başlangıç popülasyonu ve kontrol popülasyonu ortalaması ile kazanç sırasıyla 4,8; 8,9 ve 4,1 olarak elde edilmiştir. 3. tek yumru ağırlığı için en yüksek seleksiyon diferansiyeli, fidelik popülasyonu ortalaması ve kazanç sırasıyla düşük düzeydeki p=0,20’de 1,4 g; 10,9 g ve 9,5 ve p=0,25 oranında sırasıyla 1,2 g; 12,1 g ve 10,9 olmuştur. 4. bitki verimi için en yüksek seleksiyon diferansiyeli, fidelik popülasyonu ortalaması ve kazanç, p=0,10 oranında seleksiyonda sırasıyla 6,7 g; 94,9 g ve 8,2 ve p=0,15 oranında ise sırasıyla 5,9 g; 125,4 g ve 119,5 olmuştur. Sonuç olarak yumru sayısı ve bitki verimi için yüksek ve orta şiddette p=0,05; p=0,10 ve p=0,15 seviyelerinde uygulanacak seleksiyonun başarılı olduğu ortaya çıkmıştır. Tek yumru ağırlığı için düşük düzeyde uygulanan örneğin p=0,20 ve p=0,25 seviyelerde uygulanan seleksiyon başarılı görülmüştür. Patates ıslahında tek bitki verimi için uygulanan seleksiyonda orta düzeyde (p=0,15) seleksiyon ile yüksek verim elde edilmektedir.Öğe NEW POTATO BREEDING CLONES FOR REGIONAL TESTING IN WESTERN TURKEY(Soc Field Crop Sci, 2020) Ozturk, Gulsum; Yildirim, ZihinCrosses were made between 4 potato genotypes and the registered variety Nif in 2015. The F-1 seeds obtained from these crosses were grown in pots in the greenhouse to obtain potato clones. The clones selected were grown in seedbeds in 2016 and clones with high yield and tuber number were selected. Selected clones were grown in the field and selection was applied for high yield and yield components. The results obtained could be summarized as followings: There were significant variation among the clones and some of them had higher yield than that of the control genotypes. The following 20 clones were selected for the regional yield trials: 3, 21, 184, 185, 194, 195, 196, 202, 204 (Agria x Nif); 89, 90 (6/7 Clone x Nif); 205 (Juwel x Nif) and 153, 159, 160, 163, 164, 174, 176, 177 (Bettina x Nif).Öğe A RESEARCH ON IMPROVING SEED QUALITY (PELLETING) IN TRUE POTATO OF 101 (NIF) GENOTYPE(Parlar Scientific Publications (P S P), 2021) Dumanoglu, Zeynep; Ozturk, GulsumTrue potato is one of the most preferred crops in human diet. Mechanization is widely used in the production of potato which is reproduced vegetatively using its tubers. Generative reproduction, on the other hand, is done using potato seeds which are referred to as real potato seeds (RPS). This study aims at identifying the general features of the 101 (Nif) real potato seeds and the seed quality with pelleting which is known as a technique for increasing seed quality. Organic and inorganic materials were used as pelleting materials. Several physical (form, size, area, sphericity, thousand-grain-weight), physiological (seedling emergence and time), and mechanical (natural accumulation angle) quality parameters were examined. It was found that the pelleting technique increased the seed size by 1-1.5 times and the seed weight by 1.5 times in true potato seeds. Moreover, the pelleted seeds germinated (81.33%) more than the control group.Öğe STABILITY ANALYSES FOR DOUBLE CROPPING IN SOYBEAN [(Glycine max L.) Merrill](Soc Field Crop Sci, 2018) Ilker, Emre; Kocaturk, Mehmet; Kadiroglu, Abdullah; Altinbas, Metin; Yildirim, Aliye; Ozturk, Gulsum; Yildiz, HakanDouble crop agriculture is a great advantage for the coastal Mediterranean climate. Although a number of soybean varieties have been recommended for cultivation, the information on the stability for double cropping is lacking for the agro-climatic conditions of Mediterranean coastal zone. Ten high-yielding advanced soybean [Glycine max (L) Merr] lines and four registered soybean varieties having maturity group III and IV (ARISOY, ATAEM7, BRAVO and NOVA) were evaluated for double cropping in different regions and years (2014, 2015 and 2016 in Izmir-Bornova, 2015 and 2016 in Antalya-Aksu). The F test was first applied to check differences of the deviation variances from the zero. In addition, statistics of ecovalance (W-i(2)) and stability variance (sigma(2)(i)), estimating the contribution of a genotype to total Genotype x Environmental interaction (GxE), were estimated. As a result of this research, two different conclusions were determined. If sufficient water is provide (500-700 mm) BATEM 306 and BATEM 317 lines can be grown, otherwise, the other two (BATEM 207 and BATEM 223) can be suitable to grow in the regional conditions.Öğe TUBER CHARACTERISTICS OF DISEASE FREE MERISTEM CLONES OF SOME POTATO GENOTYPES(Soc Field Crop Sci, 2020) Ozturk, Gulsum; Yildirim, ZihinPotato seedlings of various potato genotypes free from the following viruses PVS (potato viruses S), PVX (potato viruses X), PVY (potato viruses Y), PLRV (potato leafroll virus), PVA (potato viruses A) and PMTV (potato mop-top viruses) were obtained via meristem culture and they were increased in vitro. Seedlings were grown in the greenhouse and mini tubers obtained were tested in the seed bed and in the field trials. When the results of greenhouse experiment were evaluated: clone Nif-1 was found to be high for single tuber number (3.0). Clone 6/7-1 had high means as compared to the remaining for single tuber weight (5.2 g) and single plant yield (14.5 g). The highest mini tuber number was obtained from Clone 6/7 in seedbed experiment. Also Hermes-1 had higher means for single tuber weight and Clone 122-1 had the higher means for plant yield and plot yield than that of other clones. Clones Atlantic-2; 3 and 1 (5.8 cm) had high tuber width and clone Hermes-1 and 2 (6.6 cm) had the highest means for tuber length in the seedbed trial. Based on the results of field experiment the highest minituber numbers were obtained from Clone 6/7-2 (10.7) and Clone 6/7-2 (10.3). Atlantic-1 (136.5 g) had high mean for tuber weight as compared to other clones. Nif-1 had the highest mean for plant yield as 920.2 g. Clone 122-1 was found to be higher than the other clones for plot yield (5.3 kg). Clones of Atlantic-1; 2 and 3 (5.9 cm) had high tuber width and clones of Juwel-1; 2 and Hermes-2 (6.8 cm) had the highest means for tuber length.Öğe UNIFORMITY OF POTATO MINITUBERS DERIVED FROM MERISTEM CULTURES OF NUCLEAR SEED STOCKS(Soc Field Crop Sci, 2011) Ozturk, Gulsum; Yildirim, ZihinThe uniformity of minitubers of meristem plantlets obtained from the meristems of nuclear seed stocks in the laboratory were studied in the greenhouse during 2008 and 2009. Tuber number per plant (TNP), tuber yield per plant (TVP) and single tuber weight (STW) were recorded on the 10 randomly selected plants in two consecutive years. Based on the statistical analysis there was significant variation for genotype in terms of TNP and TYP. Year and genotype x year components of variation were not significant as expected. STW did not have any significant variation for genotype, year and their interaction. Granola had higher means such as 3.3 in 2008 and 3.7 in 2009 than Hermes for TNP (2008: 2.6 and 2009: 3.0). Within Granola and Hermes the means of TNP, TYP and STW of 2008 and 2009 were not different from each other. In conclusion, the uniformity of minitubers within cultivars during the propagation of 2 years indicated that nuclear seed stocks could be used in minituber production in the greenhouse for more than one year.Öğe YIELD PERFORMANCES OF PELLETED TRUE POTATO (TPS) SEEDS IN OUTDOOR SEEDBED GROWING(Soc Field Crop Sci, 2021) Ozturk, Gulsum; Dumanoglu, ZeynepYield performances of pelleted true potato seeds were tested in the outdoor seedbed growing at Bornova-Izmir, Turkey in 2017 and 2018. Micro yield trial was arranged in a Completely Randomized Design (CRD) with following treatments: seedling from pelleted seed (SPS), seedling from non-pelleted seed (SNPS), pelleted single seed (PSS), pelleted two (double) seed (PDS), pelleted three (triple) seed (PTS), non-pelleted seed (NS) and minituber (MT). The following results were obtained the PTS had the highest tuber number (9.1); the PDS had the highest single tuber weight similar to the control MT; the PTS had the highest plant yield (182.3 g); the PTS had the highest plot yield (1.0 kg) with the MT (Control); the PDS had the highest tuber width (3.4 cm) similar to the MT (control) and the PDS had the highest tuber length (4.2 cm) similar to the MT (4.1 cm) and PSS (4.0 cm) he high mean for the agronomical traits indicated that pelleted potato seeds could be successfully used in the outdoor seedbed growing.
