Abstract


Wild rocket (Diplotaxis tenuifolia) is a fourth generation vegetable with an increasing awareness of benefits in human alimentation. Such species should be conserved in seed banks in order to maintain their diversity. The phenotypic characterization of the accessions stored in such banks is mandatory but requires a high amount of resources. This study focusses on the assessment of the phenotypic variability in seedling stage in order to reduce the time and costs for the characterization of germplasm. Eight wild and cultivated accessions were used. The variability was average and high even in this early stage. All the parameters measured gave a wide picture of the differences between cultivars. The conclusion is that, unless seed is needed, it is less expensive and faster to assess the phenotypical differences between cultivars only in plantlet stage and good overview of the characters is obtained.
