Abstract(s)
A collection of 155 accessions of ancient Portuguese common beans (Phaseolus vulgaris L.) was evaluated
in relation to the content of 8minerals (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.
