  Background and Objective: The hybrid rice varieties are recommended for commercial cultivation in their individual countries but in the present study, researchers were tried to find out the genotypic ability of some exotic varieties in Bangladesh climatic condition. An experiment was carried out to investigate the genotypic ability of 17 exotic hybrid rice varieties by assessing morpho-physiological and yield attributing traits grown in Mymensingh, Bangladesh. Materials and Methods: The Randomized Complete Block Design (RCBD) was followed in the experiment with 3 replications of each treatment. Data were collected randomly from 5 selected plants per plot and the following parameters were recorded during the course of the experiment such as plant height, number of effective tiller, panicle length, days to maturity, unfilled grain, filled grain, grain length, grain width, date of 50% flowering, 1000 seed weight and yield per hectare. Then, one way analysis of variance (ANOVA) were done with the help of computer software package MSTAT-C program. Results: The divergence among the genotypes for all traits studied was found highly significant at 5%. level. The mean values for plant height ranged from 89.6-109.5 cm, number of effective tillers per plant from 6.12-11.32, panicle length from 17.43-25.18 cm, 1000-seed weight from 19.89-34.62 g and grain yield from 6.67-10.85 t ha–1. Higher grain yield (10.85 t ha–1) was harvested from cultivar HS-916 closely followed by the genotype HSD-651 (10.06 t ha–1) and HS-100 (9.83 t ha–1).Grain yield was significantly (at 5% level) and positively correlated with days to flowering, days to maturity, panicle length, filled grains per panicle and 1000 grain weight. The results further revealed that genotypes with medium plant height and maturity produced the highest number of tillers and ultimately gave maximum yield. Conclusion: After assessing all the characters, the hybrid variety HS-916 produced the highest grain yield along with HSD-651 and HS-100, those may be recommended for cultivation in Bangladesh climatic condition for higher yield.
