Abstract
By challenging a heterogenous population of plants (rapid-cycling Brassica rapa L.) with waterlogging stress, we selected plants which differed in their response to root zone hypoxia. These individuals were placed into «tolerant» and «sensitive» populations based on foliage colour after waterlogging and were then mass-pollinated and re-selected over seven generations to produce the stable populations described. To assess responses to root zone hypoxia in the selected populations, plants were grown for 1 week after germination under normal watering conditions and then subjected to waterlogging stress for up to 8 d. Under control conditions, no differences were found between the tolerant and sensitive populations in any of the parameters studied
