Growth and yield of three indigenous varieties (Lalmota, Moulata and Sadamota) of aman rice was compared with that of two high yielding varieties (BRRI dhan 41 and BRRI dhan 44) in tidal floodplain ecosystem for two growing seasons. 45 d old seedlings transplanted in seedbed experienced repeated cycles of tidal submergence. Depth and duration of tidal flood differed between two growing seasons. Compared with high yielding varieties (HYVs), indigenous varieties developed longer seedlings and accumulated more dry mass prior to transplanting that helped survive repeated submergence. Planting density of indigenous varieties was about the half that of HYVs but developed more tillers per unit areas than HYVs. Seedlings of HYVs that survived had moderate tillering. HYVs ceased to develop tillers prior to flowering stage but the indigenous varieties continued growing tillers till maturity. In 2011-2012 season, HYVs produced higher yield than indigenous varieties but the trend reversed in the subsequent growing season. Number of panicles per unit area, number of spikelets per panicle, and 1000-grain weight largely contributed to higher yield. In absence of submergence tolerant HYVs, growing of indigenous rice varieties in the south central coastal region of Bangladesh could be the farmers’ better choice.
