An experiment was conducted in Orissa, India, during 2005-06 with 20 Indica rice (Oryza sativa) cultivars to study the feasibility of employing chlorophyll fluorescence as a selection tool for submergence tolerance in rice. Fourteen-days-old seedlings were completely submerged for 2, 4, 6, 8 and 10 days. Chlorophyll a fluorescence was recorded at a regular interval of 2 days up to the day 8 in fully dark-adapted detached leaves after subjecting the plants to 1 hr of re-emergence.
