The present investigation was carried out to screen the set of 2000 rice genotypes including germplasm, released varieties, INGER nurseries and elite lines for anaerobic germination trait. Based on initial screening of  2000 genotypes, five hundred lines were selected for further to study the trait based on parameters namely germination percentage, seedling length and vigour index. Frequency distribution was calculated for the three observations under study. Out of five hundred genotypes under study, 16 genotypes were not germinated, while 100 % germination was recorded by 17 genotypes. The seedling length of the germinated seeds was in the range of 1 cm (E 199 and E 282) to 62 cm (E 480), While vigour index was ranged from 20 (E199, E282 and E532) to 4880 (E1777). After repeated screening, 13 entries namely E775, E1810, E596, E1786, E 753, E773, E1846, E1195, E1049, E1772, E1723, E1701 and E1777 were recorded 100% anaerobic germination with high seed vigour index, was identified as tolerant genotypes for the anaerobic germination. These genotypes could be used as parents to introduce anaerobic germination tolerance into improved cultivars to utilize under direct seeded conditions.
