Waterlogging or submergence or flooding is one of the important environmental constraints that reduces both growth and survival of sugarcane, which cause 15–45 % reduction in cane yield and sugar recovery. Extent of injury/damage due to waterlogging depends upon the genotypes, environmental conditions, stage of development and the duration of stress. The response of sugarcane for agro-morphological, physiological, biochemical and anatomical traits decide its tolerance under waterlogging conditions. The development of root and stalk aerenchyma, adventitious roots stimulated by ethylene and auxin help the plant to cope anoxia and hypoxia like conditions. Involvement of related species of Saccharum genera carrying stress tolerance genes can be utilized in on-going sugarcane breeding programmes. Moreover the genomic approaches in sugarcane has opened new avenues for the use biotechnology i.e. in identification of genes/quantitative trait loci, to create transgenic related to the abiotic stress and to develop molecular markers for integrating marker assisted selection (MAS) in sugarcane improvement. This article provides an insight of recent advances in strategies for sugarcane response to waterlogging stress.
Key words: Sugarcane, Agro-morphological traits, Abiotic stress, Waterlogging, Quantitative traits.
