A pot experiment was carried out at the pot yard of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during kharif-1 season to evaluate the performance of five summer tomato genotypes (CLN 2418, CLN 2443, CLN 2366, CLN 2413 and J-5) on the basis of some important morphological and yield components. The experiment was conducted in Completely Randomized Design with three replications. The collected data were analyzed statistically and means were adjudged by DMRT at 5% level of probability. Results revealed that there were significant genotypic differences in respect of all parameters studied. It was further revealed that in general, high yielding genotypes showed superior performance in respect of yield contributing characters compared to low yielding ones. The genotypes, CLN 2418 and CLN 2443 produced higher fruit yield (1.49-1.54 kg plant-1) with the highest being in CLN 2418 (1.54 kg plant-1) due to its superiority in respect of all yield contributing characters. In contrast, CLN 2366 produced the lowest fruit yield (1.25 kg plant-1) due to poor performance in yield contributing characters. Further, harvesting duration was the highest in CLN 2418 (36 days) and the lowest was in CLN 2443         (30 days). But the keeping duration was the highest in CLN 2443 (9 days). CLN 2418 also showed 7 days shelf life when stored in room temperatures without deteriorating the quality in summer season.
