A multi-partners strategy is engaged at level of Burgundy-France territory, to evaluate potentials and identify levers for the development of a chain from production to uses of grain legumes. The analysis of genotype x environment interaction and climatic factors is supported by a second year of field trials of grain legumes varieties (pea and faba bean of spring or winter sowing types. The statistical analysis of climatic data over the 1961-2009 period, has allowed to build Burgundy maps of freezing risk and late spring heat stress risk and we are able to suggest pea or faba bean genotypes, better adapted to the region. The sustainability of cropping systems involving or not grain legumes was evaluated according several criteria (agronomy, energy and other input, work organisation). It has confirmed the positive effect of inserting grain legumes, on the reduction (i) of N fertiliser, energy and pesticide uses, (ii) for easier weed control (iii) on the economic bilan assessed over whole cropping system. On 2 sites, « in situ » most measurement of N2Oemissions by soils containing grain legume crop residues were higher than those containing cereal residues. Offering to farmers varieties with good level of stress resistance and good productivity will be a key point for the development of grain legume crops. The economic analysis has identified the potential value of developing contracts between produces and collectors which will secure prices and market. The technical development of a high quality “chain” and its promotion may be valuable provided efforts on traceabilty and on labelling.
