Bean is an important legume for human consumption in Europe, where the sold between exports/imports is minus 360000 t in 1998 (both Phaseolus and Vigna beans are included). So an improved sustainable and more economic common bean production, leading to high quality products would, on the one hand, contribute to the diversification of agricultural systems and the development of more environmental-friendly agricultural practices. On the other hand it would allow for an increased independence from the world market characterised by cost fluctuation and unpredictable supply.The Concerted Action is carried out with financial support from the Commission of the European Communities. FAIR programme, number FAIR5-PL97-3463, title "Improvement of sustainable Phaseolus production in Europe for human consumption - PHASELIEU".Peer reviewed
