The common bean landraces from Basilicata (Southern Italy): an example of integrated approach applied to genetic resources management.

Ex situ conservation of genetic resources has contributed to the improvement of several food crops through utilisation of preserved germplasm, but it is not the only approach to safeguard genetic resources. Presently, in situ methods are being examined as effective complementary strategies to preserve diversity along with the dynamic environment. Examples of de facto on farm conservation, a form of in situ, have been described. However, their future is unpredictable without the relief of formal scientific projects or appropriate regulations. Recent European Community regulations have introduced the possibility to attribute marks of origin and quality to local typical products. These marks can be an important support to on farm maintenance of élite landraces of principal crops. In the frame of a collaboration between the Italian gene bank and a farm (of the agricultural research service of Basilicata region), an integrated approach, involving ex situ and on farm conservation, was adopted to safeguard common bean landraces from Basilicata. The main result of this project was the attribution of IGP (indication of geographic provenance), an European Community mark, to some tested landraces.
