Field pea is very important pulse crop mainly cultivated in the temperate regions of the world. In the current study micro and macronutrients concentration was evaluated in the seeds of Turkish pea germplasm. Total 152 landraces and 5 commercial cultivars were collected from diverse geographic regions of Turkey. We found high diversity of nitrogen (N) (22.3-66.7 g kg(-1)), phosphorus (P) (1.48-8.47 g kg(-1)), potassium (K) (6.7-18.7 g kg(-1)), iron (Fe) (38.6-320.9 mg kg(-1)), zinc (Zn) (11.3-82.9 mg kg(-1)), copper (Cu) (10.5-50.8 mg kg(-1)) and manganese (Mn) (10.2-37.9 mg kg(-1)) in Turkish pea germplasm. Average concentrations of N, P and Zn were observed higher in landraces while K, Fe, Cu and Mn concentration were found higher in commercial cultivars. Correlation among different mineral nutrients was positive and significant. Principal component analysis grouped the studied germplasm into two groups and first two principal components accounted about 56.88% of the total observed variations. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) based clustering distinguished all germplasm according to their Mn concentration in pea seeds. Results from this study expressed a high range of diversity in the Turkish pea germplasm for micro and macronutrient elements. These findings will prove a valuable resource for the development of biofortified pea cultivars and varieties through conventional and modern breeding technologies and this intra variation could be used for identifying linked markers though genome wide association studies and identifying diverse parents for Quantitative trait locus (QTL) mapping.
