Description
The experiment was conducted in greenhouse conditions at Vietnam National University of Agricultureto investigate genotypic variation in morphological and physiological responses of five soybeancultivars to waterlogging at the flowering stage. Seeds of each cultivar were sown in pots containing 6kg dry soil. At early flowering stage, treatment pots were subjected to waterlogging by maintaining thewater level of 3 cm above the soil surface for ten days. The results showed that the nodule number,nodule dry weight, chlorophyll content, carbon exchange rate, dry matter accumulation and nitrogencontent were significantly reduced in waterlogging conditions. Among soybean cultivars, D140 andD912 showed better root length, nitrogen accumulation and total biomass under waterloggingconditions. Breeding for higher root growth, maintaining high nitrogen accumulation and total biomasscould be an important strategy to improve soybean cultivar for waterlogging tolerance.
