Özet:

In this study, yield components (ash, carbohydrates, crude fibre, energy, protein and sucrose), vitamins (retinol, thiamine, riboflavin, niacin, pyridoxine, folate and Ldehydroascorbic acid), macro-micro nutrients (phosphorus, potassium, magnesium, calcium, sodium, zinc and iron) and amino acids (alanine, proline, arginine, aspartic acid, methionine, glutamic acid and phenylalanine) of two bean genotypes (Phaseolus vulgaris L. cvs. Yenice and Pinarli) were investigated. Yenice and Pinarli bean genotypes (Phaseolus vulgaris L.) commonly grown in Çamoluk region in Central Black Sea Region of Turkey were used as the plant material of this study. Significant differences were observed in ash, crude fibre, lipids, moisture, protein, salt and sucrose content of bean genotypes. While sucrose (4.56 g 100 g-1), salt (0.12 g 100 g-1) carhydrates (38.41 g 100 g-1) and crude fiber (25.57 g 100 g-1) values were higher in Pinarli , lipids (1.69 g 100 g-1) and protein 21.72 g 100 g-1) contens were higher in Yenice genotype.  Similarly, vitamin levels were also significantly different. Thiamine (0.50 mg 100 g-1), niacin (3.82 mg 100 g-1),  retinol (4.15 µg 100 g-1), riboflavin (0.16 mg 100 g-1), pyridoxine (0.33 µg 100 g-1) and folate (234.50 µg 100 g-1) contents of Pinarli genotype were significantly higher than Yenice. Potassium content (16145.0 mg kg-1) of Yenice genotype and phosphorus content (8349.1 mg kg-1) of Pinarli genotype were also found statistically significantly. Except for tryptophan and phenylalanine, significant differences were also observed in amino acids of bean genotypes. Amino acid content of Pinarli genotype was also higher than Yenice genotype.Both genotypes were especially rich in aspartic acid, lysine and glutamic acid.
