Assessment of Micro and Macro Nutrients Contents in the Turkish Faba Bean Germplasm

Abstract

Abstract Faba bean (Vicia faba L.) is one of the most important legume crop and cultivated nearly all parts of the world. Present study was aimed to investigate the variation in the micro and macronutrients concentration in the Turkish faba bean germplasm. A total of 200 landraces and 3 commercial cultivars were collected from the different geographical regions of Turkey. Study was conducted at the research and experimental area of Department of Crop and Animal Production, Vocational School of Sivas, University of Cumhuriyet, Sivas, Turkey in 2016. Result of this study reflected higher level of diversity for studies nutrients; (N) (5.21-8.15 %), phosphorus (P) (0.1-0.98 %), potassium (K) (0.94-5.6 %), magnesium (mg) (0.32-0.42), calcium (Ca) (0.50-1.50), copper (Cu) (8.13-34.23 mg kg-1), zinc (Zn) (28.42-64.33 mg kg-1), iron (Fe) (44.86-128.53 mg kg-1), and manganese (Mn) (16.56-35.76 mg kg-1). Average concentrations of micro and macronutrients were found higher in the landraces as compared to the commercial cultivars. Principal component analysis grouped the studied germplasm into two groups on the basis of their Zn concentrations. Results from this study expressed the presence of high range of diversity in the Turkish faba bean germplasm for micro and macronutrient elements. Findings of this study will serves as starting point for the development of improved faba bean varieties through conventional and modern breeding technologies and these variations will be helpful for the identification of linked markers through the genome wide association studies and identifying diverse parents for quantitative trait locus (QTL) mapping.
