Abstract Autochthonous germplasm collected in Spain (Ca´diz and Baleares provinces), Italian ecotypes and cultivated material supplied by a commercial firm were analysed by using a multivariate approach applied to a set of morphological traits. According to these analyses the cultivated material could clearly be separated from the autochthonous germplasm. Variation was observed among the traits studied; Principal Stem Diameter, Leaf Area at Flowering and Susceptibility to Oidium were the main traits in grouping and separating “sulla” (Hedysarum coronarium L.) entries. A new ecotype (“Tarifa”) could be used in plant breeding as being a source of resistance to Oidium. The multivariate approach appears to be a valid system for germplasm evaluation in “sulla” with a higher discriminant capacity than multiple single trait analysis.
