    F2 populasyonundaki bezelye hatlarının soğuğa dayanıklılıklarının belirlenmesi
    (Selçuk Üniversitesi Fen Bilimleri Enstitüsü, 2018-01-10) Tekin, Nur Banu; Ceyhan, Ercan
    Araştırma "Tesadüf Parsellerinde iki Faktörlü Faktöriyel Deneme" desenine göre üç tekerrürlü olarak kurulmuş ve Selçuk Üniversitesi, Ziraat Fakültesi, Tarla Bitkileri Bölümü tam kontrollü araştırma serası ve laboratuvarlarında 2015 yılında yürütülmüştür. Bu araştırma ile soğuk stresine dayanıklı uygun bezelye genotipleri belirlenmiştir. Ayrıca soğuk stresine karşı bitkiler tarafından oluşturulan biyokimyasal, fiziksel özellikler veya fiziksel savunma mekanizmaları ortaya konulmaya çalışılmıştır. Araştırma sonuçlarına göre; soğuk zararı bakımından Melrose, Şahin, Granger, 4053 x Melrose, 4053 x Hadim, Şahin x Hadim ve 3057 x Melrose, peroksidaz içeriği bakımından 3057 x Melrose, 4053 x Melrose, 3029 x Melrose, 3029 x Granger ve 4053 x Hadim, süperoksit dismutaz içeriği bakımından 3053 x Melrose, Şahin x Hadim, 4053 x Melrose, Şahin x Melrose ve 3029 x Melrose ve prolin içeriği bakımından 3031 x Granger, 3055 x Melrose, Ultrillo, 3057 x Hadim ve Şahin x Hadim genotipleri ilk sıralarda yer almıştır. Sonuç olarak, soğuk stresinin bezelye genotiplerinin yapraklarındaki enzim aktiviteleri üzerine etkileri ele alındığında; genotipler içerisinde en dayanıklı olarak 3031 x Granger ve 3055 x Melrose genotipleri ön plana çıkan bu genotipler daha sonra yapılacak olan soğuğa dayanıklılık ıslah çalışmalarında kullanılabilirler.

    Genetic Variability Studies in F2 Generations of Determinate High Yield Dry Bean Lines for Seed Yield and Yield Components
    (Selçuk Üniversitesi, 2022) Tekin, Nur Banu; Ceyhan, Ercan
    Dry bean is the third most important pulse crop which is widely adapted and can improve soil fertility in Türkiye. The genetic variability and association studies help in selection which would increase the yield potential of dry bean. The F2 generation and parents (Kınalı, Alberto, Great, Göynük, Özmen) obtained by diallel hybrid method (5 x 5 and 20 combinations were obtained) were sown in the experimental field of Selçuk University Faculty of Agriculture in 2021.In the research, measurement, counting, weighing and analysis of plant height, pod height, number of seeds per plant, number of seeds per pod, seed yield per plant, hundred-seed weight, protein ratio, protein yield in the plant were made. In the F2 generation, the seed yield values in plant of the hybrids are between 23.63 g/plant (Kınalı x Özmen) and 97.45 g/plant (Alberto x Kinalı). Heterosis values of seed yield in plant range from -50.72% (Kınalı x Özmen) to 93.01% (Kınalı x Göynük), heterobeltiosis values varies from -58.92% (Kınalı x Özmen) to 77.26% (Göynuk x Özmen). The protein ratio of the crosses in the F2 generation ranged from 23.05% (Alberto x G Northern 59) to 29.12% (Özmen x Alberto). Heterosis values of protein ratio are between -18.33% (Alberto x G Northern 59) and 7.23% (Özmen x Alberto), heterobeltiosis values are between - 22.27% (Alberto x G Northern 59) and 5.82% (Özmen x Alberto). As a result of this research, a sufficient level of genetic variation was determined in the population, considering the agronomic characteristics examined. Determination of suitable parents and hybrids for green bean breeding in terms of sustainability of calcareous soils, agronomic characteristics and inheritance of these parents and hybrids were determined.

    Kireçli Topraklara Uygun Kuru Fasulye (Phaseolus Vulgaris L.) Genotiplerinin Bazı Tarımsal Özelliklerinin Kalıtımlarının Diallel Analiz Metoduyla Belirlenmesi
    (Selçuk Üniversitesi Fen Bilimleri Enstitüsü, 2022) Tekin, Nur Banu; Ceyhan, Ercan
    The research was conducted between 2019-2021. In 2019, five dry bean varieties (Kınalı, Alberto, Great, Göynük, Özmen) were planted in the Fully Controlled Plant Breeding Greenhouse of the Faculty of Agriculture of Selçuk University. Diallel hybridization method was applied (5 x 5 with was obtained 20 combinations). The obtained hybrids were planted in the Selcuk University Faculty of Agriculture experimental field in 2020. Obtained F1 seeds were sown again in the second year (2021) in the experiment field of Selçuk University Faculty of Agriculture. In the research, measurement, counting, weighing and analysis of plant height, pod height, pod width, number of pods, number of seeds per plant, number of seeds per pod, grain yield per plant, hundred-seed weight, protein ratio, protein yield in the plant were made. Grain yield values per plant of hybrids in F1 generation 13.72 g/plant G Northern 59 x Göynük with 32.38 g/plant Alberto x Kinali, in F2 generation 23.63 g/plant Henna x Özmen with 97.45 g/plant Alberto x Henna is among them. Additive gene effects were observed for the pod width trait in the F2 generation, for the pod length trait in the F1 generation, and for the plant height trait in the F2 generation, in both generations for the grain number trait in the plant. Non-additive gene effects were detected in other traits. The values of the protein ratio of the crosses in the F1 generation were 22.55% (Alberto x G Northern 59) and 29.35% (Özmen x Alberto), in the F2 generation 23.05% (Alberto x G Northern 59) and 29.12% (Özmen x G Northern 59). The majority of the crosses showed positive heterosis and heterobeltiosis values for grain yield in the F1 and F2 generation, the high mean of heterosis indicates that the additive genes are insignificant. The negative results of heterosis and heterobeltiosis mean for protein ratio in F1 and F2 generations indicate non-additive gene effect.
