Abstract: An experiment was conducted at two locations of Sylhet district of Bangladesh with seven hybrid rice genotypes of Bioseed India Ltd (Bio-404, Bio-453, Bio-543, Bio-460, Bio-648, Bio-649 and Bio-650) to evaluate their yield potentials. The experiment was laid out in a randomized complete block design with three replications. Results indicated, Bio-649 produced the highest yield with short duration and less disease infection. The maximum grain yields of Bio-649 were 9.1 and 10.46 t ha^-1, respectively at Sylhet Agricultural University (SAU) farm and farmer’s field, Khadimnagar. These yields were higher than the two check varieties at both locations. The lowest grain yields of the hybrid rice genotype Bio-648 were 4.23 and 7.16 t ha^-1, respectively at SAU and farmer’s fields. The results revealed, Bio-649 is suitable for Aman season and can be considered to proceed with further research at several locations of Bangladesh.
