Öğe Evaluation of advanced lentil lines for diversity in seed mineral concentration, grain yield and yield components(Ankara University, 2017) Toklu, Faruk; Özkan, Hakan; Karaköy, Tolga; Coyne, Clarice J.Lentil is one of the most important grain legumes, which plays a significant role in human nutrition and animal feed through the world. In developing countries, the prohibitively high cost of meat has rendered, lentil, with its high seed protein and essential amino acid content, important source of dietary protein. In this research, 181 lentil advanced lines (F7 generation) of Karacadağ x Silvan and Karacadağ x Çağıl 2004 crosses were evaluated for grain yield, yield components and seed mineral concentrations in two diverse environments in Turkey. Considerable diversity was observed with regard to yield components and seed mineral concentrations in the advanced lentil lines. The greatest phenotypic diversity was observed in the biological yield, number of pods and weight of pods per plant, the number of seeds and weight of seeds per plant, and seed Ca, Zn and Fe concentrations. Grain yield per plant was significantly positively correlated with the biological yield per plant, number of pods per plant, weight of pods per plant, and number of seeds per plant. Plant grain yield and yield components were strongly positively correlated with seed potassium (K), calcium (Ca), magnesium (Mg) and zinc (Zn) concentrations but was negatively correlated with Fe concentration. In conclusion, promising lentil advanced lines for the grain yield, yield components and mineral concentrations could be evaluated for developing new lentil varieties and spesific breeding purposes. © Ankara Üniversitesi Ziraat Fakültesi.Öğe Evaluation of Advanced Lentil Lines for Diversity in Seed Mineral Concentration, Grain Yield and Yield Components(ANKARA UNIV, FAC AGR, 2017) Toklu, Faruk; Ozkan, Hakan; Karakoy, Tolga; Coyne, Clarice J.Lentil is one of the most important grain legumes, which plays a significant role in human nutrition and animal feed through the world.

COLLECTION FOR AGROMORPHOLOGICAL AND SEED MINERAL CONCENTRATIONS(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2016) Toklu, Faruk; Coyne, Clarice J.; Asikli, Safiye; Aydin, Oguzhan; Karakoy, Tolga; Ozkan, HakanA collection of common bean comprising totally 223 accessions of which 176 genotypes from the USDA, 37 common bean landraces and 10 commercial cultivars from Turkey, evaluated for several agromorphological plant characters and mineral concentrations in seeds. There were wide range of variations for the investigated agromorphological characters and mineral concentrations. The majority of the common bean genotypes had indeterminate climber growth habit (35% and 69% for collection and cultivars respectively), with white flower color (46% for collection 100% for cultivars). The majority of the USDA collection and Turkish landraces had very small seed size (52%) while common bean cultivars had medium and average seed size (38% respectively). The results showed that several genotypes such as Pinck, Feijao Pico de Oro, Estrada Rosado (Colombian genotypes), 08KMY0F25, 12KMYOF8 and 12KMYOF17 (Turkish landraces) found to be promising genotypes for grain yield and yield components. The genotypes G878, G16837, Frijol canario, P8474-A-D (from USDA collection), 12KMYOF25 landrace and Goynuk cultivar (from Turkey) were found to contain high Fe and Oaxana 5-1, Queretaro 7-5, Frijol canario and Negro for high Zn seed concentrations. The first two principal components (PC1 and PC2) which are the most important components accounteds for 29.78% and 18.70% of total variation respectively. PC1 is positively correlated to yield components such as number of pods per plant, weight of pods per plant, number of seeds per plant, weight of seeds per plant and grain yield per plot while PC2 is positively correlated to the seed Zn, Fe, Cu and Mn concentrations.
