Transient waterlogging reduces the yield of cool-season grain legumes in several parts of the world. The tolerance of grain legumes to waterlogging may vary between and within species. This study investigated the effects of 7 days of waterlogging and subsequent recovery ( 10 days) on plant growth to evaluate the variation in tolerance among 7 cool- season grain legume species, in sand culture in glasshouse experiments. Additionally waterlogging tolerance of 6 faba bean genotypeswas also evaluated. Tolerance towaterlogging as indicated by root and shoot growth ( as% of drained controls) was ranked as follows: faba bean> yellow lupin> grass pea> narrow- leafed lupin> chickpea> lentil> field pea. Faba bean produced adventitious roots and aerenchyma leading to increased root porosity ( 9% gas volume per unit root volume). Among the 6 faba bean genotypes screened, accession 794 showed the best waterlogging tolerance, but it was also the slowest growing accession, which might have contributed to apparent tolerance ( i. e. growth as % drained control). It is concluded that waterlogging tolerance in grain legumes varied between and within species, with faba bean being the most tolerant. The variation in tolerance identified within the limited set of faba bean genotypes evaluated suggests scope for further genetic improvement of tolerance in this species.
