In this era of continuous industrialization and deforestation, where climate change is inevitable, adequate cereal crop production to meet global hunger is extremely difficult. Drought is one of the most alarming constraints to rice production. The purpose of this study was to assess the drought tolerance ability of six rice landraces grown in the western lateritic area of West Bengal along with an already established drought-tolerant variety. Drought stress was induced on the seeds during germination using Poly-Ethylene-Glycol (PEG) at three different concentrations (5, 10, and 20%). Morphological and biochemical parameters like germination percentage, root length, root-shoot ratio, proline accumulation, survivability was estimated after 10 days of treatment. Under stress, land races accumulated more amount of proline indicating better tolerance. The stress induction at the germination stage reduced the yield of 3 landraces by 8-10% whereas production of the check variety was reduced by 20%.These landraces were collected from rural areas where farmers do not cultivate them commercially but maintain them each year traditionally. These landraces if involved in breeding programs can be modified to develop high-yielding, true-drought-tolerant, climate-resilient variety that can ultimately benefit the farmers in coming days.
