Newly released rice varieties BRRI dhan93, BRRI dhan94 and BRRI dhan95, are suitable for rainfed lowland ecosystem of Bangladesh as an improvement over existing rice varieties. These varieties have satisfactorily been passed in the proposed varietal trial conducted at the farmers’ field. As a result, National Seed Board (NSB) approved these for commercial cultivation in the wet season in September 2019. BRRI dhan93, BRRI dhan94 and BRRI dhan95 have modern plant type with 117, 118 and 120 cm plant height and matures in 134 days, 134 days and 125 days with production of 5.8, 5.9 and 5.7 t/ha yield respectively. BRRI dhan93 has deep green leaf, erect flag leaf, late leaf senescence, 1000 grain weight is 18.95 g having reddish colored medium bold grain. BRRI dhan94 has deep green leaf, semi-erect flag leaf, 1000 grain weight of 18.60 g having reddish colored medium bold grain. BRRI dhan95 has deep green leaf, erect flag leaf, 1000 grain weight is 21.50 g and medium bold type deep red coloured attractive grain. BRRI dhan93, BRRI dhan94 and BRRI dhan95 are highly promising rice varieties for cultivation in the rainfed lowland area which help farmers to obtain high economic output and contribute to sustaining food security.
