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