The morphological characterization of plant is the basic criteria in order to provide fundamental information for plant breeding programme. The present study was conducted to characterize the geographical indication (GI) rice cultivars grown in Bangladesh on the basis of morphological characteristics at Bangladesh Rice Research Institute, Gazipur. The data were recorded on 53 different agro-morphological traits (37 qualitative and 16 quantitative). The rice germplasm exhibited sufficient genetic variation for most of the qualitative and quantitative traits. Variation was observed for all the qualitative traits except ligule color, leaf blade pubescence and panicle threashability. Rice cultivar Begunbichi took minimum days to 50% flowering; Pashusail and Digha showed superiority for panicle length; Horkoch showed the maximum value for 1000-grain weight and Pashusail showed the highest yield potential. The genetic potential of cultivars Pashusail, Biruin, Balam, Digha, Horkoch, Binni and Begunbichi on account of excellent performance for various traits can be used in future rice breeding programmes.
