FIELD COLLECTION AND CONSERVATION OF NON-CULTIVATED EDIBLE SPECIES IN THE GERMPLASM BANK OF ZARAGOZA (SPAIN)
There is a high number of non-cultivated edible plant species. Some of them are still appreciated and consumed, in other cases their consumption is only in the memory of the elderly people and the knowledge about these species is at risk of disappearing. Within the framework of the Spanish project The genetic resources of edible underutilized species: field collection, multiplication and conservation in the germplasm bank during 2009 various collecting expeditions across Aragón, a region of 47,720 km2 in the northeast of Spain, were performed with the following aims: 1) to compile information about wild species used for food, either nowadays or in the past, 2) to locate these species within their natural habitat, 3) to classify them taxonomically, and 4) to obtain some seeds and maintain them under long-term storage conditions. To compile the information a list of descriptors to capture the knowledge of edible wild plants as described by farmers and other people in farming communities has been developed. A total of 27 localities have been visited and 31 personal interviews have been carried out. Most of the informants were well over 66 years old. A total of 93 accessions were collected, belonging to 16 families and 28 species. All the seeds are held in the Germplasm Bank of Zaragoza at -18°C and 4% RH. These species include: Allium ampeloprasum L., Anchusa italic Retz., Asparagus acutifolius L., Borago officinalis L., Bryonia dioica Jacq, Chondrilla juncea L., Eruca sativa Mill., Foeniculum vulgare Mill., Lactuca serriola L., Picris echioides L., Rorippa nasturtium-aquaticum (L.) Hayek, Rumex acetosa L., Scolymus hispanicus L., Scorzonera laciniata L., Silene vulgaris (Moench) Garcke, Silybum marianum (L.) Gaertn. and Taraxacum officinale Weber.
