摘要：
In the present study, 243 lowland rice genotypes were screened for anaerobic germination (AG) under 10 cm of flooding in plastic trays. Forty three genotypes showed anaerobic germination. Pre-sowing seed treatments of the genotypes by soaking, priming with water, 1% KCl and 5% PEG each for 24 h revealed enhanced AG and other seed germination parameters under flooding compared to control. Priming could induce AG in the genotypes that failed to germinate under submerged condition. Hydro-priming and 1% KCl priming found to be the best treatments showing the usefulness of pre-sowing seed treatments. Jala-shree, Jalkuwari and Ranjit Sub1-C-376, having sub-mergence tolerance, were identified as potential genotypes for AG and hence can be used in breeding programmes.
