Interpretive Summary: A collection of common bean comprising totally 223 genotypes 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, with white flower color. The majority of the USDA collection and Turkish landraces had very small seed size while common bean cultivars had medium and normal seed size. The results showed that several genotypes such as Pinck, Feijao Pico de Oro, Estrada Rosado (Colombian genotypes), 12KMYOF8 and 12KMYOF17 (Turkish landraces) found to be promising genotypes for grain yield and yield components. The genotypes G878, Z#4, G16837, Frijol canario, P8474-A-D (from USDA collection), 12KMYOF25 landrace and Göynük cultivar (from Turkey) were found to contain high Fe and Oaxana 5-1, Queretaro 7-5 and Negro for high seed Zn seed concentrations. Useful variation for bean improvement was found for 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 in addtion to useful variation for important mineral nutrients seed Zn, Fe, Cu and Mn concentrations.

Technical Abstract: A collection of common bean comprising totally 223 genotypes 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 varieties respectively), with white flower color (46% for collection 100% for varieties). The majority of the USDA collection and Turkish landraces had very small seed size (52%) while common bean varieties had medium and normal seed size (38% respectively). The results showed that several genotypes such as Pinck, Feijao Pico de Oro, Estrada Rosado (Colombian genotypes), 12KMYOF8 and 12KMYOF17 (Turkish landraces) found to be promising genotypes for grain yield and yield components. The genotypes G878, Z#4, G16837, Frijol canario, P8474-A-D (from USDA collection), 12KMYOF25 landrace and Göynük cultivar (from Turkey) were found to contain high Fe and Oaxana 5-1, Queretaro 7-5 and Negro for high seed Zn seed concentrations. The first two principal components (PC1 and PC2) which are the most important components accounted for 29.82% and 20.68% 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.
