Diversity of seed mineral composition of Phaseolus vulgaris L. germplasm

Pinheiro, C., J. P. Baeta, A. M. Pereira, H. Domingues, and C. P. Ricardo. "Diversity of seed mineral composition of Phaseolus vulgaris L. germplasm." Journal of Food Composition and Analysis. 23 (2010): 319-325.


A collection of 155 accessions of ancient Portuguese common beans (Phaseolus vulgaris L) was evaluated in relation to the content of 8 minerals (Zn, Cu, Fe, Mn, Ca, Mg, P and K) important for human nutrition. A high degree of variability for P. Fe, Zn, Cu, Mn and Ca was observed in the collection. Total correlation matrix analysis revealed the existence of two important sets of strong positive correlations (P <= 0.0001), one involving P, Fe, Zn, Cu and protein, and the other Ca and Mn. The principal component analysis showed that Zn, Fe and Cu are highly correlated to the first component (27% of variability) and Mn and Ca to the second component (22% of the variability). The high mineral variability observed in the seeds of this common bean collection could be useful for the selection of cultivars with higher nutrition value and for the improvement of seed nutrition quality traits.
